A 'Blue Marble' photograph of the Earth taken from the VIIRS instrument aboard NASA's Earth-gazing satellite - Suomi NPP – on Jan. four, 2012.
Planet Earth doesn't prize a climb certificate to record its formation, which aptitude scientists spent hundreds of years struggling to assess the age of the planet. through dating the rocks in Earth's ever-changing crust, as well because the rocks in Earth's neighbors, such because the moon and touring meteorites, scientists prize calculated that Earth is four.54 billion years historic, with an mistake achieve of fifty million years.
How historical are your rocks?
Scientists prize made several attempts to date the planet during the last four hundred years. They've tried to predict the age in accordance with changing sea stages, the time it took for Earth or the solar to chill to latest temperatures, and the salinity of the ocean. as the courting expertise progressed, these methods proved unreliable; for example, the upward propel and drop of the ocean became shown to breathe an ever-altering procedure as opposed to a progressively declining one.
And in an extra exertion to calculate the age of the planet, scientists became to the rocks that cowl its surface. youngsters, as a result of plate tectonics normally adjustments and revamps the crust, the first rocks prize lengthy on the grounds that been recycled, melted down and reformed into recent outcrops.
Scientists additionally prize to battle an issue called the terrific Unconformity, which is the position sedimentary layers of rock seem dote lacking (on the grand Canyon, as an example, there may breathe 1.2 billion years of rock that can not breathe found). There are distinctive explanations for this uncomformity; in early 2019, one anatomize suggested that a worldwide ice age caused glaciers to grind into the rock, inflicting it to crumble. Plate tectonics then threw the crushed rock back into the indoors of the Earth, getting rid of the historical proof and turning it into recent rock.
in the early twentieth century, scientists subtle the procedure of radiometric dating. earlier analysis had proven that isotopes of some radioactive elements decompose into other features at a predictable cost. by using examining the current aspects, scientists can calculate the initial amount of a radioactive factor, and thus how lengthy it took for the facets to decay, allowing them to verify the age of the rock.
The oldest rocks in the world discovered up to now are the Acasta Gneiss in northwestern Canada near the first-rate Slave Lake, which might breathe 4.03 billion years historical. but rocks older than three.5 billion years can moreover breathe organize on everyone continents. Greenland boasts the Isua supracrustal rocks (three.7 to 3.8 billion years historical), whereas rocks in Swaziland are 3.4 billion to 3.5 billion years. Samples in Western Australia elope 3.four billion to three.6 billion years historical.
research corporations in Australia organize the oldest mineral grains in the world. These tiny zirconium silicate crystals have a while that attain 4.three billion years, making them the oldest substances organize in the world to this point. Their source rocks haven't yet been found.
The rocks and zircons set a reduce restrict on the age of Earth of four.3 billion years, since the planet itself prize to breathe older than the ease that lies on its surface.
When lifestyles arose is silent below debate, mainly as a result of some early fossils can emerge as herbal rock types. one of the most earliest sorts of being prize been present in Western Australia, as announced in a 2018 study; the researchers discovered tiny filaments in 3.four-billion-year-old rocks that could breathe fossils. different experiences imply that being originated even past. Hematite tubes in volcanic rock in Quebec could prize covered microbes between three.77 and four.29 billion years ago. Researchers taking a peep at rocks in southwestern Greenland additionally saw cone-like structures that could prize surrounded microbial colonies some three.7 billion years in the past.

with the intention to further refine the age of Earth, scientists everyone started to seem outward. The cloth that shaped the solar equipment became a cloud of filth and gasoline that surrounded the younger solar. Gravitational interactions coalesced this cloth into the planets and moons at about the equal time. through getting to know other bodies within the photo voltaic equipment, scientists are capable of finding out more about the early historical past of the planet.
the closest constitution to Earth, the moon, would not event the resurfacing methods that happen across Earth's panorama. As such, rocks from early lunar historical past silent sit down on the surface of the moon. Samples back from the Apollo and Luna missions revealed a while between 4.4 billion and 4.5 billion years, helping to constrain the age of Earth. How the moon fashioned is a bethink of debate; whereas the paramount thought suggests a Mars-size expostulate crashed into Earth and the fragments at last coalesced into the moon, other theories imply that the moon fashioned earlier than Earth.
apart from the colossal bodies of the photo voltaic device, scientists prize studied smaller rocky company which prize fallen to Earth. Meteorites spring from lots of sources. Some are forged off from other planets after violent collisions, whereas others are leftover chunks from the early photo voltaic outfit that on no account grew giant satisfactory to kindly a cohesive physique.
despite the fact no rocks had been intentionally returned from Mars, samples exist within the kind of meteorites that fell to Earth long in the past, enabling scientists to construct approximations concerning the age of rocks on the pink Planet. Some of those samples were dated to four.5 billion years historical, supporting different calculations of the date of early planetary formation.
A four.four billion year historical zircon crystal from Australia is the oldest piece of Earth yet discovered. The source rocks for the minuscule shards prize not yet been identified.

more than 70 meteorites which prize fallen to Earth prize had their ages calculated via radiometric relationship. The oldest of these are between 4.four billion and 4.5 billion years historic.
Fifty thousand years ago, a rock hurled down from region to kind Meteor Crater in Arizona. Shards of that asteroid had been gathered from the crater rim and named for the regional Canyon Diablo. The Canyon Diablo meteorite is crucial because it represents a class of meteorites with components that permit for extra exact courting.
In 1953, Clair Cameron Patterson, a prominent geochemist at the California Institute of expertise, measured ratios of lead isotopes in samples of the meteorite that put tight constraints in the world's age. Samples of the meteorite pomp an expansion from 4.53 billion to four.fifty eight billion years. Scientists interpret this achieve as the time it took for the solar gadget to conform, a gradual adventure that took vicinity over approximately 50 million years.
by using no longer only the rocks in the world however additionally suggestions gathered in regards to the system that surrounds it, scientists had been capable of position Earth's age at about 4.54 billion years. For comparison, the Milky manner galaxy that incorporates the solar system is approximately 13.2 billion years ancient, while the universe itself has been dated to 13.8 billion years.

Discussions about Java EE‘s future persist. After JAXenter launched its interview succession with Java EE Guardians, people started a conversation on Reddit, so they decided to stir it here and invite everyone to participate.
Java Champion Lukas Eder
We asked Java Champion Lukas Eder to remark on the current state of Java EE, as well as on the climb of Java EE Guardians and MicroProfile.
JAXenter: Considering the current state of Java EE, attain you speculate they need an initiative to protect its legacy?
Lukas Eder: That’s a very exciting open-ended question. And they can peep at it from different angles (all subjective, of course). First off:
Do they need Java EE in the first place?
The Java EE “market” is big; a lot of companies (let’s muster them companies) want to build “standard” software and a lot of infrastructure software vendors (let’s muster them vendors) want to earn a piece of the cake by selling “standard” software platforms (and/or services related to the “standard” platforms) to these companies.
These companies want to prize as cramped cognitive friction as feasible when going from one project to the next, but it is a venomous thing to prize too many choices in terms of technology. They pay the vendors to guarantee this lack of friction. Many companies earn a free ride because many vendors present the platform software for free as Open Source.
There is no Java EE standard.
Java EE evangelists used to dote to paint a standards-biased picture where the UI framework market (often their favorite example) was shared mostly between Java EE’s JSF and Spring’s MVC. Of course, as the epigram goes: “The only statistics you can confidence are those you falsified yourself”. If you peep at “the market” from a different angle, there’s moreover Angular JS which dominates it, probably much more than JSF and MVC combined.
We’ve had Struts, before that JSP (still the best Java web UI tech if you question me) and before Java EE (and before J2EE), there were other technologies, and surely, in the future, there will breathe other technologies. And that’s just talking about UI frameworks. So, you can remark that even within the “standards” scope there are a lot of choices — which is not surprising, given XKCD 927.
So, in my opinion, there is no Java EE standard. Java EE is only a recommended set of libraries that are guaranteed by Java EE certification to work together.
Therefore, the reply to the question attain we need Java EE in the first position is “Yes.” However, this is the case only if said certification is your highest priority as an API consumer. Spring is an alternative to the Java EE “standards” where innovation and recent features are added without too much of a formal process by a solitary vendor: Pivotal. They silent add exactly the selfsame value as Java EE to most customers, though. That value is: “It just works”. The dissimilarity is the following: there’s no certification, but confidence in the vendor after many years of excellent delivery. And, there’s no competition in the implementation process because many APIs are proprietary Open Source.
Spring is an alternative to the Java EE “standards”.
Of course, if you build decent integration tests yourself, there’s a third alternative to Java EE and Spring. You don’t need either. You can pick any whimsical set of third party libraries as long as you confidence each individual vendor to “do the prerogative thing” (which is often the case anyway, no matter if you’re using Java EE or Spring). For instance, if you’re using jOOQ (or Hibernate), you can exhaust that library in a “standalone application”, in a Spring application, or in a Java EE application just the same.
Now back to the actual question:
Do they need a group dote the Java EE Guardians?
If Java EE was a truly open benchmark (like HTML, or SQL to some extent), they wouldn’t breathe in the situation that we’re in. Oracle would just breathe one more stakeholder in a large consortium and it would breathe their own selection whether they withdraw from the consortium or not, without affecting the consortium as a whole.
Still, because of the way the JCP is organized, Oracle pretty much dictates what happens in the “standard”. For instance, the TCK for most aspects of Java EE are not open, freely available or even available without the need to accept very restrictive terms.
Should Oracle “secretly” want Java EE’s death, then that’s exactly what’s going to happen.
Now, Oracle seems to prize lost interest in Java EE (although they attain not know that for sure) and frankly they didn’t attain an excellent PR job explaining their strategy. There is a lot of skepticism in the industry with respect to the future of Java EE. Given Oracle’s taut grip on the legal aspects of Java EE, there can breathe no fork or truly open benchmark without Oracle’s consent. So, should Oracle “secretly” want Java EE’s death, then that’s exactly what’s going to happen.
I personally don’t speculate the Java EE Guardians can attain a lot in this case. It’s worth trying, sure. The Guardians everyone prize a gargantuan personal stake given the fact that their professional careers depend on Java EE. But as I explained above, there are non-certified alternatives dote Spring, or random third party library collections that attain the job just the same, so, perhaps, the best way to stir forward is to create a recent “Spring” from scratch that is governed by a legal open benchmark consortium, free from any legal ties to Java EE, and with or without Oracle. Let’s muster it … “Summer” (Note that the community just published “MicroProfile”, which seems to breathe an initiative which does precisely that.)
JAXenter: How could Java EE breathe brought forward? Should Oracle breathe convinced that they will earn a better recur from continuing to invest in Java EE? Should the focus remain on the community’s support?
Lukas Eder: There was an exciting discussion on Reddit’s /r/java just recently. /user/thesystemx, who frequently comments on the subject, said:
At last Devoxx I spoke to several spec leads and people from Oracle, and they told me (off the record) that the direct licensing income lonesome is enough to elope Java EE, and that excludes the tag on sales for related products.
And my first thought was…
The direct licensing income of a solitary Exadata installation is probably enough to elope Java EE as well, so perhaps this is an order of magnitude thing (i.e. a “what’s this boring, irrelevant stuff over there cease wasting my time thing”)
As you can see, as a community, they can only speculate about what’s going on prerogative now. I believe that the trade is not exciting enough for Oracle. Plus, neither is the community because it isn’t Oracle’s. It’s Red Hat’s, Pivotal’s, IBM’s, and everyone else’s community. Oracle inherited a rather difficult legacy from Sun. Jonathan Schwartz (the former Sun CEO) testified in court in the Oracle vs. Google case that Java was “free”. Quoting from the Ars Technica series:
The strategy was, they conform on these open APIs, then they compete on implementations.
This is what an open benchmark does, and it was certainly Sun’s intention to “sell” Java EE as an (almost) open standard. But perhaps, after everyone these years. After doing some proper math, it just showed that this particular (almost) open benchmark provides benefits to competitors much more than to Oracle. Again, as we’re lacking official PR from Oracle, they can only guess. The fact is, they as a community cannot bring forward Java EE without Oracle. Oracle CEO Safra Catz made this very lucid in the Oracle vs. Google lawsuit:
[…] And that Android was an unauthorized fork of Java.
This means that any unauthorized fork of Java EE will have the selfsame portion as Android. Besides, I sincerely doubt that they can convince Oracle to give us more free lunch, so the future of Java EE is, without an actual statement from Oracle’s side, on hold.
Mike Croft —Java Middleware consultant at Payara
We asked Payara’s Mike Croft to remark on the current state of Java EE, as well as on the climb of Java EE Guardians and MicroProfile.
JAXenter: Considering the current state of Java EE, attain you speculate they need an initiative to protect its legacy?
Mike Croft: work on Java EE has slowed, but it hasn’t stopped. The JCP involves more than just Oracle, though they are the biggest players at the moment. The Java EE Guardians’ focus is on getting some action from Oracle; their opinion is that this is crucial to the success of Java EE. I conform that movement from Oracle is significant for the future of Java EE, whether that is Oracle working on the JSRs they lead or in relinquishing them to the community. It is significant to bethink that Java EE isn’t only Oracle, however, and there are a huge number of people and corporations of varying size which prize a vested interest in its future. The Guardians group is just one exertion of many and everyone efforts are needed in this, just as in any community-led project.
Java EE isn’t only Oracle, however, and there are a huge number of people and corporations of varying size which prize a vested interest in its future.
JAXenter: How could Java EE breathe brought forward?
Mike Croft: Java EE already has a way to stir forward in the version 8 specifications. My personal view is that Oracle can silent stand to grow their trade by investing in Java EE. They prize not heard any official, public response from Oracle as to their plans, so they can’t breathe sure that the lack of activity is permanent or only temporary as they consequence more resource into the “other projects” that has been notable on mailing lists. We, as a community, can’t stand silent and wait for confirmation, though.
It’s this lack of information which has driven Red Hat, Payara, Tomitribe, IBM and the LJC, who each prize significant interests in Java EE, to promulgate microprofile.io as a way to bring about open collaboration. This is not an exertion designed to exclude Oracle, but to leverage the incredible power of the wider Java community to address the needs of modern Java EE users. The train is to iterate quickly and to collaborate openly on a standard. Standards are incredibly significant in technology to avoid fragmentation and, from here, the future looks bright.
Java Champion Lukas Eder
JAXenter: Mike Croft said that the JCP involves more than just Oracle. What’s your pick on that?
Lukas Eder: That’s exactly how it ought to be, but for historic reasons it’s not true, and probably never will be. The JCP *is* Oracle, mostly, from a legal and operative perspective.
But Payara and the others who joined forces to create this MicroProfile initiative can create their own committee (as I’ve mentioned in my previous responses on JAXenter), which is truly open, governed by a foundation, not a corporation. There will silent breathe politics, of course, but it would certainly attend stir this forward as the legal hurdles would probably breathe much reduced.
[MicroProfile’s strategy is to] tangle up with Spring whose Spring Boot totally dominates the microservices hype.
JAXenter: attain you speculate MicroProfile is hoping for a reaction from Oracle?
Lukas Eder: I speculate that MicroProfile backers attain not want to add more FUD to the debate. They thus openly invite Oracle to join. In my opinion, however, the strategy is to stir forward with innovation and not wait for Oracle, but most importantly: to tangle up with Spring whose Spring Boot totally dominates the microservices hype. If Oracle does determine to become fragment of MicroProfile, fine. But in my opinion, that would breathe rather surprising.
JAXenter: He moreover mentioned that “standards are incredibly significant in technology to avoid fragmentation”; you said there is no Java EE standard. Why are your viewpoints so different?
Lukas Eder: Of course he says that. He couldn’t elope Payara and not prize this opinion :).
And I don’t fully disagree with Mike. What I weigh in by Java EE is not a “standard” is this: There are good, “obvious” standards and less good, less “obvious” ones.
A apt standard is a benchmark that removes fragmentation where fragmentation creates friction, overhead, bureaucracy in the market without adding any value. apt examples for apt standards are:
Electric outlets (I silent hope there will eventually breathe a world-wide standard, instead of dozens, but at least the EU mostly uses just one)
Train track widths
DIN A4, A5 paper formats
All of these standards simplify trade for everyone by destroying the trade of those who try to sell deviating, proprietary interfaces. For example, DIN A4 means 297mm x 210mm. Vendors of printers, photocopying machines, document processing software, paper, envelopes, binders, briefcases, etc. etc. can everyone advocate “the standard” and consumers don’t prize to purchase a briefcase for JAXenter publications and a different briefcase for other documents.
A unpleasant benchmark is a “standard” that hinders innovation by adding complexity in a very opinionated environment.
JDBC is an exceptionally apt benchmark in software, as it removes the need for knowing about vendor-specific APIs and network protocols in order to access mostly RDBMS (although it works moreover with other data stores).
There are some apt Java EE standards, dote JMS, Servlets, JavaMail and others, mostly those that define (again) protocol abstractions, or things that are too handrum to breathe implemented a second time in a different way (JAXB, JavaMail).
A unpleasant standard is a “standard” that hinders innovation by adding complexity in a very opinionated environment, where differing opinions are apt for the market, as each opinion can vary greatly in how it adds value to a consumer. There are a lot of trade standards dote the ISO 9001 for character management or the ISO 29119 software testing standards, which are mostly certifications that companies dote to pomp off to impress customers. They don’t really weigh in anything concrete as it is much too knotty to derive from a simple yes/no flag what this really means in the context of a concrete corporation.
Java EE “shines” here with unpleasant “standards” dote EJB, MVC, JPA, JSF, CDI, Bean Validation, Batch, and much more. everyone of these things attain not belong in a benchmark because they are:
Often a unpleasant default choice
Often not the only choice, specifically not the de-facto selection (e.g. bean validation, batch)
Very opinionated in terms of architecture and design, which greatly restricts the solution space for consumers
Take JSF, for instance. It’s a server-side UI component API specification. How many component APIs did they already have? AWT, Swing, JavaFX, Gwt, Vaadin, Wicket, JSF, and many others, lesser known ones. In this case, JSF is “just another” component API (specification). Of course, it’s one of the most Popular ones today, but that’s only the case because it profits from the Java EE “brand”.
JPA is a different story. It solves dozens of problems, which is a very unpleasant thing for a “standard” API. It solves:
Mapping (that’s the best part)
Querying (in several different, conflicting ways: mapping, utility finder methods, JPQL, criteria API, fetch graphs, aboriginal queries, query annotations, etc. etc., None of them are satisfactory, given that SQL is incredibly more powerful)
Native SQL (in my opinion, the stored procedure advocate shows the desperation in this API to hold up with true world needs by shoe horning a feature into an API that was not designed for the mere being of stored procedures)
Transactions (Why? There’s already JTA…)
It’s a heterogeneous monster that should breathe split in 10 different APIs. Don’t earn me wrong. It’s fine for an *implementation* dote Hibernate to present everyone these features out of the box. But the specification shouldn’t attain that. It’s simply not a apt standard.
To reply your question: As I mentioned already in my previous answers, the industry likes having guarantees that certain things work together. It’s apt to know that JDBC works and that jOOQ or Hibernate work on top of JDBC and that None of these APIs will burst in the future. JDBC is a standard. jOOQ and Hibernate aren’t. They’re knotty tools that profit from the standard. They drive innovation. They add things, deprecate things, remove things. They should not breathe standards. Otherwise, their knotty innovation will stop.
I’m hoping that the MicroProfile initiative will pick a fresh peep at “standardization” in Java and prevent the “standard feature creep” that has happened in J2EE and later on in Java EE from happening. brand Little’s remark on the topic looks precisely dote it.
Java Rock Star Adam Bien
JAXenter: Considering the current condition of Java EE, did they need an initiative dote MicroProfile? Should Oracle pick fragment in this initiative?
Adam Bien: Sure! Oracle is highly welcome.
JAXenter: attain you speculate MicroProfile will prize any repercussion on Java EE Guardians?
Adam Bien: Java EE Guardians is just another group of passionate Java EE fan girls and fan boys. I’m sure they prize it. At least they retweeted everything what was microprofile.io-related.
I will question the Java EE Guardians about their opinion next time I earn the chance.
JAXenter: Mike Croft said that the JCP involves more than just Oracle while Lukas Eder opined that the JCP is Oracle. What is your opinion?
Adam Bien: I asked the question myself. I asked Heather VanCura What is the relation between JCP and Oracle? The reply can breathe organize here.
Oracle has a permanent seat on the JCP Executive Committee (EC), and together with the other EC members, the EC votes on the work of the Expert Groups and evolves the JCP itself. The EC is led by a non-voting Chair from the PMO; the PMO is the group within Oracle that is answerable for administering the JCP and chairing the EC. The EC does not micro-manage the day-to-day workings of Expert Groups – the EC has the opportunity to review the work of each Expert Group at well-defined points as their specifications proceed through the JCP program. The primary office of the EC is to ensure that specifications attain not overlap or fight with one another and that the specifications meet the needs of the industry segment for which they are being written.
On the spec-level it is even clearer. Some specs JSR-365, CDI 2.0, Dependency Injection for Java, JSR 330 were / are led by other companies entirely without Oracle.
More to come.

Sun Microsystems previews the next version of its lightweight OSGi-based GlassFish Enterprise Server Version 3 with today's release of a "Prelude" edition.
The current GlassFish V2 open source version of Java Platform Enterprise Edition (Java EE) 5 application server is Popular with developers working on Web services, service-oriented architecture, and loaded Internet applications (RIA). GlassFish V3 is based on the upcoming release of Platform Enterprise Edition 6 (Java EE).
Both GlassFish V3 and Java EE6 are scheduled to breathe released in Spring 2009 around the time of the next Sun-sponsored JavaOne conference in San Francisco, said Paul Hinz, director of Java Enterprise System at Sun. The preview of GlassFish helps developers work with recent features supporting RIA development as well as more traditional serverside development, he said.
"When GlassFish V3 comes out next spring it will present complete app server advocate for Java EE 6 in both the Web tier and the app tier," he said. "GlassFish V3 Prelude allows you to prize one development in your Web tier and the selfsame development in your app tier. So you can exhaust the selfsame deployment methodology, management and tests."
Jonathan Eunice, principal IT Advisor at Illuminata, Inc., cautions that for everyone the recent features to advocate Web applications, this is a preview release without complete Java EE6 support.
Prelude to a GlassFish"The biggest downside I remark to the V3 Prelude is that, in obeying the rules of the open road to release early and earn users' hands on it, it doesn't prize the [full functionality], and it has a shorter than usual advocate lifetime," Eunice said.
Both the Sun executive and the analyst pointed to V3 advocate for dynamic languages, especially Ruby via JRuby, as a plus for developers working on Web and RIA applications.
Specific to Ajax development, John Clingan, GlassFish project manager, notes that the recent GlassFish offers complete Comet support.
"Comet enables applications that are propel enabled," Clingan explained. "Typically a user has to propel refresh to earn recent data. But with Ajax the server can propel data rapidly down to the client. GlassFish V3 Prelude supports Comet prerogative out of the box."
GlassFish supports OSGi, which is moreover supported by Sun's vie in Java, the IBM/Oracle-backed Eclipse Foundation, which offers Swordfish as its OSGi implementation.
"OSGi is a dynamic module system for Java, something which brings added versatility to any initiative pegged to the Java platform," explained SearchSOA columnist Daniel Rubio, earlier this year in What OSGi means to SOA. "This versatility comes in a way that was missing in many of the core parts related to Java, whether it breathe in Java application servers, the latest Java trade Integration (JBI) service bus model, or, inclusively, the Java Virtual Machine itself."
In Clingan's view, OSGi provides a way to extend the functionality of the core application tier through OSGi bundles.
"If you've written a set of functionality and bundled it up as OSGi with the intent of pushing it to multiple application servers that advocate OSGi, you can now attain that with GlassFish V3 Prelude," Clingan said.
However, Eunice is a cramped skeptical of the current enthusiasm for OSGi. The basic strategy of the OSGi modular app server is "don't load what you don't need, improving startup times and aptitude to customize what functions are provided."
But the analyst said that in his opinion "there's a cramped 'fetishization' of OSGi in the industry prerogative now, when it's really the performance or other delivered attributes that are truly important, not OSGi per se. But OSGi does attend earn to that better performance/modularity, so it's apt - just not particularly worthy of the idol worship it sometimes receives."
Of practical weight to developers in V3 Prelude, Eunice said are "easier to configure, easier to deploy, easier to connect to development tools," notably NetBeans or Eclipse.
He moreover said the latest version of GlassFish is well positioned as an alternative to Tomcat.
Eunice said: "I speculate there's now a apt argument: if you're using Tomcat for Java Web apps, uh, why are you doing that? V3 Prelude doesn't implement the complete Java EE model, but for the lighter weight Web apps that don't need or exhaust EE, it's a very nice option." He notes that Java EE5 is in GlassFish V2, and Java EE6 will breathe in the complete GlassFish V3 next year.
For SOA, Clingan notes that in V3 "we're offering an upgrade version of their Web services stack, called Project Metro. It offers Microsoft .NET 3.5 Web services interoperability.
The technology platform SAP NetWeaver forms the basis of everyone applications (photo: Fotolia)
SAP NetWeaver is the technology platform on which everyone applications run, from SAP trade Suite, SAP ERP, and SAP Customer Relationship Management through custom developments. As middleware, SAP NetWeaver ensures that the SAP software runs smoothly and enables developers to build their own applications. The platform comprises SAP NetWeaver Portal, SAP NetWeaver Mobile, SAP NetWeaver Composition Environment (SAP NetWeaver CE), and SAP NetWeaver Process Integration (SAP NetWeaver PI). For more information about SAP NetWeaver, you can moreover check out their article Integrating Third-Party Software into SAP.
Over the past few months, rumors that SAP plans to sideline SAP NetWeaver prize been circulating, creating considerable skepticism among customers about the future of SAP’s technology platform. But at TechEd 2010 in Berlin, CTO Vishal Sikka dispelled everyone doubts and presented SAP NetWeaver 7.3.
The recent version is set to become available at the start of 2011 and provides a whole achieve of revised functions. For example, release 7.3 supports Java EE 5 as well as Enterprise Service Bus (ESB) for Java. The Java Message Service (JMS) is moreover recent as a publish-and-subscribe function. Furthermore, SAP NetWeaver 7.3 supports WS Policy 1.2, SOAP 1.2, WS confidence 1.3, Java SE 6, JSR 168/286, WSRP 1.0, and SAML 1.0/2.0.
Evaluating data in true time
SAP NetWeaver 7.3 is well equipped for in-memory computing. The SAP High-Performance Analytic Appliance (SAP HANA) software enables rapid access to applications and supports different application areas such as analyses, performance, and management. Because the server runs parallel to the database, the data required becomes available even faster.
A particularly practical feature is that up to 40% more users can access the recent version of SAP NetWeaver. Release 7.3 supports SAP trade Suite upgrades in the live system. This means that enhancement packages can breathe imported easily and with minimum downtime.
With the recent version, SAP promises a number of improvements for employees working in the province of application development, particularly – but not exclusively – mobile applications. Microsoft outstrip files can breathe integrated with the recent version, too. Further collaboration functions are moreover available in the form of enterprise workspaces and Duet Enterprise software. This enables more people to work on one project at the selfsame time.
And for operators of online shops: SAP NetWeaver PI can connect with PayPal X payment automation platform.

Enhanced Functions in Version 7.3
Developers who program their own applications based on SAP NetWeaver can prize enhanced functions with the recent release of the technology platform. This especially applies to SAP NetWeaver Composition Environment (SAP NetWeaver CE), Web Dynpro, and SAP NetWeaver Visual Composer.
SAP NetWeaver Composition Environment: Developers who previously used Web Dynpro for Java or SAP NetWeaver Visual Composer can now exhaust SAP NetWeaver CE, as well. Those who already developed applications using SAP NetWeaver CE can now attain so using their own portal box.
SAP NetWeaver Visual Composer: SAP NetWeaver Visual Composer enables developers to create user interfaces. In the recent version, a wizard generates the conversion report. With SAP NetWeaver Visual Composer, applications with a simple user interface or Web services can breathe built. The instrument makes applications easier to program. Furthermore, SAP NetWeaver Visual Composer helps developers create user interfaces for service applications. What’s special about this is that services can breathe reproduced and simulated for test purposes. The preview button is new, as is the editor to which RTF documents can breathe uploaded.
HTML 5 is the upcoming Web standard, which adds a whole achieve of recent functions to Internet pages. In the future, the SAP NetWeaver technology platform will moreover advocate HTML 5 and on-demand services
Read on: How It’s Done: Upgrade to Version 7.3
How It’s Done: Upgrade to Version 7.3
Customers who deploy SAP NetWeaver 7.0 will need to upgrade their server to version 7.3. SAP promises that most custom developments will elope smoothly after the upgrade. However, there are exceptions for Web Dynpro, Java, and Composite Application Framework (CAF). Fortunately, there are tools for such cases – dote the design-time migration procedure. For everyone other homegrown developments that are based on Visual Composer (VC), Guided Procedures (GP), or J2EE, an upgrade is only required if there are plans to develop these homegrown developments further in the future.
Server upgrade: SAPJup is the instrument for upgrading to SAP NetWeaver 7.3. In addition, there’s a Java upgrade instrument to upgrade the Java application server to the recent version. What’s more, a part DVD called the Upgrade Master DVD is supplied. The system kind is recognized automatically, regardless of whether it is ABAP or Java. SAPJup extracts everyone the key upgrade tools and gathers information such as passwords and add-ons. The instrument moreover checks the operating system and the database, so that the target release can breathe imported. The processes are preconfigured in a shadow system. The installation and the upgrade of the individual server components are moreover performed in the shadow system. During this time, the production system remains live. As a result, the upgrade can breathe performed without delays or downtime.
Migration controller: The migration controller migrates changes from the original release to the shadow system. It enables custom-developed applications to elope on the target release.
Migrating Web Dynpro to version 7.3: A wizard helps users with the migration. For customers who are already using version 7.0, a migration is not absolutely necessary. With SAP NetWeaver CE 7.1, the source code is compatible with the Web Dynpro Java applications, but it is not binary. This means that the venerable source code needs to breathe overwritten. By contrast, the applications in SAP NetWeaver CE 7.1 are binary, which means that they update themselves automatically during the migration.
SAP Composite Application Framework (SAP CAF) from SAP NetWeaver 7.0x to 7.3: When the SAP Composite Application Framework instrument is updated, the data records are moreover transferred from SAP NetWeaver 7.0 using the migration wizard. The ease has to breathe migrated manually. During the migration, a browser window opens from which the administrator can select and synchronize the data records. The data records are automatically connected to trade objects.
SAP NetWeaver Visual Composer (SAP NetWeaver VC): User interfaces that were developed in SAP NetWeaver 7.0 attain not prize to breathe migrated, because they are updated automatically. A migration is required only for everyone those interfaces where development is not yet completed.
Guided Procedures (GP): GP objects can breathe upgraded using the benchmark upgrade process (SAPJup). After this, the processes are available in the updated SAP NetWeaver 7.3 server. The GP processes continue to elope automatically after the server upgrade.
J2EE/Java EE 5: The benchmark upgrade procedure automatically transfers everyone J2EE applications, so a manual migration is not necessary.
