(IDG) -- in order to compete in a enjoying container that includes Microsoft and solar, on September 27 IBM formally launched its developerWorks portal web site, which has been in beta seeing that June. The free online developer useful resource is a concrete expression of IBM's dedication to open necessities and pass-platform building.
The web site contains seven zones: Open source, Linux, safety, Unicode, web architecture, XML, and Java. through its dedication to provide product- and platform-unbiased information, IBM goals to develop this web site the most excellent useful resource for ebusiness application developers.
according the Chris Bahr, software director for the website, developerWorks is an extension of IBM's alphaWorks developer website, which invitations builders to participate early in the tackle development technique by means of giving them free entry to IBM source code.
DeveloperWorks's Open supply Zone is a forum for IBM's open source tasks, the region developers can enhance or restore code on unavoidable initiatives. For Java builders, this zone presents the Jikes Java Compiler, which converts Java source code into computing device-readable code to velocity Java software development.
Open Visualization statistics Explorer is a different open supply venture quickly to subsist obtainable on the web page. Bahr says original open supply tasks will subsist brought each three to four weeks; there is no note yet on plans so as to add more Java-related initiatives here.
Enter the Java Zone
The Java Zone demonstrates IBM's willingness to embrace Java expertise and, through extension, Java developers. (In contrast, the Microsoft Developer network homepage indicates no badge of Java support.) The zone links you to free on-line classes, downloads, open source code, tools, access to Java person businesses (JUGS), movements, and engage excerpts -- total concerning Java.
you will discover links to how-to articles, information, and tutorials from a considerable number of impartial sources, including Developer.com, JavaWorld, ZDNet, and TechWeb, as well as fashioned content material from IBM's own team of workers below the direction of former JavaWorld Editor-in-Chief Michael O'Connell.
compared to other supplier websites, IBM seeks to downplay self-merchandising in developerWorks. for instance, a piece of writing on the web site makes reference to the recent Volano document, which discovered that Tower expertise's TowerJ beat out IBM's original JDK 1.1.8 for Linux.
"basically, if they reflect the suggestions is crucial to developers, they will necessity to cowl it in developerWorks. No corporate developer resource presents the identical breadth and depth of content material -- freed from proprietary or company-selected constraints," says O'Connell.
DeveloperWorks additionally lets you search the internet for Java-connected material through IBM's jCentral, which gives more than 360,000 gadgets of interest to Java builders. under one percent of that content is IBM's, in response to Bahr. through jCentral, builders can search other developer net websites, equivalent to EarthWeb's Gamelan Java resource web site, total public web websites, and other corporate web websites, similar to sun's Java Developer Connection web page, as well as other IBM sites.
What does IBM hope to profit by artery of making this free useful resource available?
"We're attempting to utilize developerWorks as a artery to hold a dialog with their audience and then straight away act on the remarks they get," says Gina Poole, director of the site.
"in the starting, they noticed that builders hold been mostly focused on Linux, open source, and internet structure, so they immediately created zones for these technologies. They hope to proceed the dialog with builders about open necessities, rising applied sciences, cross-platform development -- to uphold the zones they now hold and grow the interactive content material of the web page," adds Poole.
The website makes it viable for builders to faucet into IBM resources; as an instance, Java developers can entry supply code created with the aid of some 3,000 Java developers at IBM.
The playing field
IBM's developer portal site does hold its labor cleave out for it because it competes with already-centered developer websites. or not it's presently ranked as the number three portal web page on Hot100.com's checklist of most visited developer web sites, at the back of Microsoft and solar. when you account that its promoting crusade has simply been launched this week, even though, here is an remarkable score.
The largest change between developerWorks and different supplier-backed developer sites is its focus on open requirements and product- and platform-unbiased content.
"sun and different companies noiseless view the developer world in a relatively slender sense, specializing in content that promotes their own items and technologies without delay and not bringing up different products and technologies," says O'Connell.
"IBM, in contrast, embraces with developerWorks an open, go-platform, requisites-primarily based focal point, which capacity their content material is extensively censorious -- even to builders who aren't interested in IBM items and services," continues O'Connell. "We don't seem to subsist restricted to the company's product line. here's a quite bold step, specially for a veteran company relish IBM," he adds.
subsequently, in trade for total this free content, IBM hopes builders will pick to create functions that sprint on IBM hardware and application. As O'Connell says, developerWorks "offers IBM publicity to broader developer community and showcases IBM potential."
only time will tell, youngsters, if builders will discourse in aplomb to IBM's choices.
just before joining the JavaWorld crew, Theresa Gonzalez turned into the managing editor at application structure journal. presently, she is an affiliate editor at JavaWorld.

WebSphere Portal Server and Web Services
In this paper they hold given an introduction to distributed portals and some censorious issues
regarding cooperation between portals. They hold explained the WebSphere Portal Server
architecture in generic and the web services aspects in particular. They described two ways of using
web services in the context of portals: utilize of web services by portlets and utilize of portlets as
remote portlet web services.
Through proxies generated automatically using appropriate tools, portlets are able to utilize web
services to obtain information or initiate transactions instead of the traditional mechanisms for
remote procedure calls or data queries. IBM provides tools that develop utilize of web services from
portlets very facile already today. From a given service description, tools provided in the IBM
Web Services development Environment can create ready-to-use proxy classes in Java that can
easily subsist used from portlets.
The concept of remote portlet web services will allow deploying distributed portals cooperating
within an intranet or over the internet in the near future. Portal implementations provided by
different vendors will subsist able to participate portlets and cooperate across corporate boundaries if
required. IBM WebSphere Portal Server will provide complete uphold the remote portlet web service
concept. Publishing of local portlets as remote portlet web services and integration of remote
portlet web services in WebSphere Portal Server-based portals will subsist viable with just a few
clicks by an administrator.
The skill to host portlets and publish them as remote portlet web services that can subsist integrated
into portals easily will circle WebSphere Portal Server into a platform that allows content providers
to provide content to their customers – portals – in the most easily consumable form. Also, it will
allow application providers to embed their applications into portlets and publish them as remote
portlet web services.

Whatever the industry or company size, everyday business processes require access to information resources such as data, applications and people. Providing access to total necessary information resources in a cohesive and efficient manner can play a great piece in improving employee productivity, structure successful relationships with partners and improving customer satisfaction.
IBM WebSphere Portal supplies an infrastructure to draw together access to information resources with a variety of formats. Access to total necessary data, applications and people can subsist supplied in a solitary Web browser interface. For a given process, access can subsist supplied to total the resources required to complete the process. Existing data and applications can subsist leveraged and even integrated at the user’s screen. Content can subsist personalized based on a particular user’s role, and information overload can subsist minimized. Many information resources are noiseless maintained by older suites of software that hold been purchased or developed over many years. Often, these software suites embrace character-based, green-screen applications running on IBM eServer iSeries or zSeries platforms. When developing a portal solution to draw together access to different information resources, it is likely that one or more of the required resources will subsist a green-screen application. The skill for a company to modernize and selectively and securely expand access to these green-screen applications in a portal environment can subsist a major requirement in creating a comprehensive portal solution for employees, partners, and customers.
IBM WebSphere Host Access Transformation Services (HATS) provides tools to attend quickly build portal-accessible Web applications from existing green-screen applications without having to change any code in the existing applications. With HATS, it is viable to create an easier-to-use graphical user interface (GUI) for green-screen applications. Web services can likewise subsist created that provide measure programming interfaces to business logic and transactions contained within your green-screen applications. By creating Web graphical user interfaces or Web services programming interfaces for green-screen applications, HATS can attend provide a comprehensive WebSphere Portal solution that will improve employee productivity, collaboration with partners and customer satisfaction.
The business Need
Basic needs common to running any business embrace providing efficient means of obtaining information by employees, partners, suppliers, distributors and customers. Employees must hold facile access to total necessary information to subsist productive performing both job assignments and internal company processes such as human resource activities. Partners, suppliers and distributors must subsist able to easily collaborate with the company, access information necessary to maintain inventory levels and ship and receive parts or finished products. Customers must conveniently access information with appropriate security protection to subsist able to research, order, receive and pay for products and services. The more efficiently information can subsist shared with these groups, the more productive and satisfied each group will subsist while interacting with the company.
In addition, as the requirements of managing the business change, existing processes must subsist changed and possibly integrated with other, newer processes. To withhold the cost of change low, processes must subsist made more supple and re-usable as components within a business system.
Businesses hold long used information technology (IT) systems to attend improve employee productivity, collaboration with partners, suppliers and distributors, and responsiveness to customers. Systems hold been built to maintain data and transactions necessary for doing business with external users and for managing internal processes. Over the years, these systems hold been enhanced and improved to the point where today they provide a very stable core of mission-critical applications. However, as technology has changed over time, formats and methods of access to information hold changed. So, access to varied types of information resources may subsist necessary to complete a particular process.
A key factor in improving efficiencies while interacting with employees and external users is to provide a solitary entry point and facile access to the information resources necessary to complete business processes based on the role of the End user. Employees can become more productive with access to total they necessity supplied to them in a solitary Web browser interface. External users can subsist given security-rich, role-based access to total the information they necessity to interact with the company and can Do so at their own convenience without relying on trained customer service representatives.
In many cases, the data and transactions necessary to perform a process are maintained in applications running on iSeries or zSeries platforms. Often, the only access to these applications is through the traditional green-screen interface. Although these applications are very stable and perform well, the green-screen interface is queer and difficult to utilize for many users. This interface is likewise not typically accessible by untrained employees or external users. To give original users access these applications would require Internet access, more security and a much easier interface than the green-screen interface provides. So, either the applications necessity to subsist rewritten or the access and interfaces to them necessity to subsist improved.
Mission-critical green-screen applications hold been developed and tailored over many years. Time, endeavor and resources hold been invested fine-tuning them to achieve a tall flat of performance and reliability. Rewriting or replacing these applications can subsist expensive and perhaps cost-prohibitive. Also, rewriting an existing application often increases risk in terms of stability.
The key to improving access for employees and external users, quickly and with less risk, is to improve the user interface to existing green-screen applications and develop required information and transactions Web accessible without changing the applications themselves.The Solution
WebSphere Portal along with HATS has helped many businesses meet these needs.WebSphere Portal can provide employees, partners and customers with a security-rich, solitary entry point and facile access to total the information resources they need. It is viable to customize what information you provide based on the role of the End user. uphold for a credential vault makes it viable to simplify the process for End users of signing on to multiple applications. Different portal pages can subsist supplied to attend organize the tasks and processes that are made available.
Portlets, the visible vigorous components on a portal page, are used to provide access to different information resources. They attend you control the current and array of information for the End user. The click-to-action (C2A) feature allows you to participate data between portlets to integrate data and processes between different information resources. By providing users with cohesive and efficient access to total the information they necessity in a Web browser interface, you can attend improve employee productivity, build successful relationships with partners and develop customer loyalty.
And, if a portal solution must embrace access to mission-critical green-screen applications, HATS makes it viable to quickly and easily create portlets that will provide the necessary access. With HATS, a Web-like scrutinize and feel can subsist created for your mission-critical green-screen applications without changing the applications themselves. An easy-to-use portlet interface can likewise subsist created that makes only necessary functions available to employees or external users and hides the rest. This is especially censorious in a portal environment where the screen space is shared by many portlets.
The Struts Framework from Apache is a very popular, robust Web application framework. Many corporate companies hold deployed tons of Web applications using Struts. And they hit the ground with abundant technical resources. They can develop newer applications quickly. Portal implementations present a original challenge by introducing original frameworks and APIs. To leverage existing assets and skills, WebSphere Portal supports the Struts Portlet Framework so Struts Web applications can subsist easily migrated to a portal.
The Struts FrameworkThere's tons of information on Struts, AJAX, and the Struts Portlet Framework available on the Web. In this article I'm going to provide a brief introduction to these topics; for more details check out the resources section.
The Struts Framework is an implementation of the MVC architecture, with Model being the business logic represented using JavaBeans, EJBs, etc., View the presentation layer represented by using JSPs, ActionForms, and tag libraries, and Controller the ActionServlet and Action classes (see device 1).
Struts Control FlowHere is the typical request-response cycle for the Web application using Struts:
The client requests a path matching the Action URI pattern.
The Web container passes the request to the ActionServlet.
The ActionServlet looks for the Struts configuration file, if this application has multiple modules it looks for the appropriate mapping for the given path in any of the Struts configuration file.
If the mapping specifies a figure bean, ActionServlet looks to view if one exists or it creates one.
Once the figure bean is created, ActionServlet populates values from the HTTP request. If the mapping has a validate property as true, ActionServlet invokes the validate artery on the figure bean. If the validation fails, the control current ends there.
If the Struts configuration file specifies action mapping then the appropriate action class 'execute' artery is invoked with an instantiated figure bean as a parameter.
The Action may summon other business objects and repopulate the figure bean with the latest values and other business functions as needed.
Based on where you want to ship the control next, the Action reads ActionForward and the Action URI from the Struts configuration file and returns to the ActionServlet.
If the ActionForward is a URI to the JSP to array the page, the control current ends by sending the output to the browser or if it's forwarded to another Action URI the above current starts again.
AJAX in Action
AJAX is not a original technology, but is the most happening thing in the Web world that gives a desktop or client/server application feel to your Web applications (see device 2).
AJAX Control Flow
Nothing has changed for the Web application server; it noiseless responds to each request, the artery it did it before.
The server's response only has the data it needs in the XML form, without any markup or presentation.
Most of the page doesn't change, only the parts of the page that necessity to change is updated, and that asynchronously.
Struts Portlet Framework Developers who hold relish with the Struts Framework should accommodate easily to the Struts Portlet Framework. The packaging for Struts Portlet Application is similar to a Struts application in the servlet environment. However, WebSphere Portal introduces additional challenges such as portlet modes, states, inter-portlet communications, portlet two-phase processing, and multiple device support, which are addressed through the Struts Portlet Framework. For a detailed explanation of this topic, view the Redbook IBM Rational Application Developer V6 Portlet Application development and Portal Tools.
A portlet processes and renders differently than a servlet. A servlet will Do total its processing in the service method, while the portlet will divide action processing and rendering into two sunder methods, hence portlet processing is defined as a two-phase approach. device 3 explains the two-phase processing approach of a Struts portlet. To invoke actions in the rendering facet there is a original interface called IStrutsPrepareRenderer. For more details view Executing Struts actions during the render facet of IBM WebSphere Portal.
IBM supports Struts Portlet Framework for both IBM API and JSR 168 API portlet containers. Users can easily migrate existing Struts applications to Struts portlet applications using either of the portlet's APIs. For more information on migrating and developing newer applications using the Struts Portlet Framework view the Portal Info Center.
Struts Portlets with AJAXThough AJAX isn't the birthright solution for every Web application, there's increasing curiosity and enthusiasm among organizations to explore its benefits and view how it works for their applications. AJAX isn't new, but it's total on the client side and making it labor with different server-side frameworks is a challenge. This article is a result of my client relish in developing Struts portlet applications with AJAX. In the sections above I briefly described Struts and AJAX. In the sections below I'll delineate some of the challenges faced during implementation. To develop AJAX applications there are several toolkits such as Google Web Toolkit (GWT), DOJO, AJAX Faces, and JSON, but for simplicity's sake they chose a unostentatious vanilla implementation.
Making asynchronous calls to the server using AJAX best fits a portal scenario with different portlets representing different back-end application views. However, this feature isn't supported with portlet URLs since each response from the portlet container represents a portal page with different portlets with different window states and modes. Given this limitation, the alternative they hold is the XMLHttpRequest remonstrate calling a servlet from a servlet container as depicted in device 4.
To demonstrate the above scenario I hold used the simple downloadable case shown below.
As in device 5 and device 6, when the user clicks on the menu items, the right-side blue box items collect refreshed without unloading the total page.
Below are some of the challenges they had and I'll explained how they addressed them.
