IBM building Portlets with IBM
February 18, 2019 Alex Woodie
How attain you motivate IBM i programmers to continue learning recent applied sciences, long after they hold mastered the RPG capabilities they expend the most? There’s no basic reply to that question, which was the matter matter of a fresh conversation IT Jungle had with personal home page on IBM i guru Alan Seiden and Heidi Schmidt, the head of PKS utility.
IBM i retail outlets puss a couple of interrelated complications when it involves their personnel, which traditionally is among the greatest line gadgets within the IT finances. These challenges encompass: the growing older of IBM i authorities; the retirements of child boomer-aged personnel; the difficulty in discovering proper replacements; the shortcoming of IBM i-connected practising in colleges and universities; and the should unwind and modernize monolithic purposes.
that you could add an additional to the record: building a mighty lifestyle of persistent discovering among IBM i builders and the managers who maneuver them.
At too many IBM i shops, there is a calamity of stagnation of potential among the many developers, says Schmidt, the managing ally of PKS software GmbH, which is primarily based in Ravensburg in southern Germany.
“I’m very surprised that some americans hold not executed any practicing for 25 or so years,” Schmidt says. “here is loopy because you should nonetheless breathe working towards or learning some thing new. otherwise, you’re caught on your area.”
braveness To change
Taking the first step to breaking free from that bubble of stagnation and breathe taught whatever recent may also breathe intricate – and frightening.
“RPG and COBOL developers are used to excellent lore of their world, total mastery of that area,” says Seiden, the major of Seiden neighborhood. “They’re being requested to budge past into areas where they don’t hold superb capabilities, and it’s ok. The reply might no longer breathe within the IBM guide. It could breathe on Google or finding aid from friends or consumer companies.”
Alan Seiden is the founder of Seiden neighborhood and the CIO Summit.
fear of the unknown can additionally lead builders to reject requests from management to spruce up their competencies. That’s a natural human reaction, besides the fact that it runs counter to a purpose that many corporations strive to fulfill, which is to maintain their IT gurus’ abilities antiseptic and their software code up to date.
“if you hold not erudite anything in 15 years, it’s very complicated to attain the primary working towards and learn something new. probably I’m a diminutive bit stunned of doing it for the primary time,” Schmidt says. “here is additionally a controversy for RPG programmers who are announcing ‘I don’t wish to travel to training.’ I even hold a couple of customers who broadcast ‘we might want to expend funds for practising my RPG team but they don’t are looking to go.'”
IBM i builders don’t attain themselves any favors when they thrust again in opposition t administration’s attempts to widen their technological horizons. while they may additionally suppose safer of their RPG or COBOL consolation zone, it hurts their business’s efforts to refresh its expertise and wait agile in the puss of changing company dynamics.
“It is awfully essential to construct them recollect it’s essential to breathe greater accepting of recent applied sciences,” Schmidt says. “What we're customarily seeing, as a minimum in Germany, is lots of very experienced and also first rate RPG and COBOL developers are truly very restrictive [about having] contact with recent know-how. and they also are setting up an image round their group that looks now not very captivating for management.”
That’s human nature, Seiden says. “every so often they want to hold steadiness in any respect costs, whereas industry people may exigency to suppose about future alterations the market is going to bring,” he says. “which you can’t hold equipoise at complete charges.”
faced with the verisimilitude that IBM i builders are often reluctant to gain lore of recent technologies, it falls to administration to create a drudgery environment it is extra accepting of trade – it's, to create a tradition of learning.
more Carrot, less Stick
It can breathe tempting for management to are trying to constrain a cultural alternate of their IT store. however management needs to tread carefully with their procedures and steer lucid of the temptation to impose exact terms to their crew.
Managers should soundless leverage affirmative procedures to organically develop a mighty lifestyle of discovering among builders, as opposed to needy reinforcement, or punishing developers once they fail to satisfy practising goals, Schmidt and Seiden suggest.
“we'd pick to retain issues wonderful,” Seiden admits. “I don’t definitely consider you could hearten somebody in a inventive box. people should breathe self-stimulated. however the manager must breathe capable of create an atmosphere where americans are looking to breathe enhanced and exigency to improve.”
One extraordinarily convenient strategy to motivate a conducive discovering environment is to tie bonuses to the completion of coaching. “In Germany, a number of newer application agencies, in their conclusion-of-12 months contract, they hold got paragraphs where they’re [required] to finished two weeks of coaching every year to net a bonus,” Schmidt says.
Heidi Schmidt is a managing ally at PKS application.
“one of the most a hit corporations I’ve viewed hold carried out a go-working towards program so that complete builders, no rely what technologies they use, are conversant and a diminutive equipped in complete of the languages in expend to attain simple troubleshooting and to focus on it, besides the fact that they’re no longer the expert,” Seiden says. “They’ll breathe alert of whatever thing about complete of them in order to hold comfy conversations and not retreat into their personal silo.”
The biggest problem is to create an atmosphere of mutual acceptance, and not to foster divisions about which know-how or programming language is advanced, Schmidt says.
“for example, we're doing practicing for developers, and they contemplate more and more combined teams,” she says. “we now hold a couple of consumers within the remaining 12 months, when they sent us younger individuals – Java people who needs to learn RPG. They additionally decided to ship us their [older] RPG developer and attain the selfsame practising with them from day one.”
The outcomes hold been very pleasing, Schmidt says. “I asked the 63 12 months ancient man after the first week ‘How attain you feel? attain you hold got the sentiment that you’ve realized the rest?'” she says. “He told me this turned into the first week in 20 years the situation I truly programmed a application from scratch, as a result of I at complete times copied.”
mind The Limbic
a further approach to fostering an environment of technical exploration and persistent researching is to respect that individuals view rewards and punishments in different ways. management can retain issues relocating forward via recognizing that each and every of their limbic methods – the a Part of the mind that governs punishment and reward – are wired in a diminutive alternative ways.
as an instance, Schmidt says, the limbic system can breathe programmed to reward an RPG developer for recognizing the lengthy-term value of the RPG language, and the inherent equipoise that the language can bring to the business. then again, the manager’s limbic device might also narrate her that the long-time age equipoise of RPG is definitely a needy thing, and that it receives within the means of innovation.
earlier this 12 months, PKS held a workshop to back developers embrace limbic considering into their resolution-making. (graphic courtesy PKS)
“There’s lots of research fabric purchasable that claims, as an instance, that managers are typically more interested in income and future-driven issues, enjoy recent know-how and issues enjoy that,” she explains. “And builders – notably the RPG or COBOL americans, who're already older – are greater safety-driven and they exigency not to alternate too a mighty deal. So they are attempting to appropriate this capabilities of limbic issues to net tons clearer image of why people are reacting within the means they are.”
Recognizing how different stakeholders within the IT offshoot view these huge challenges is a step toward creating a lifestyle of inclusion, where americans aren’t fearful to travel out on a limb. Managers should soundless admire that RPG and COBOL programmers are sometimes susceptible to withstand attempts to net them to conform their abilities and try recent applied sciences. And the IBM i execs should additionally realize that administration may not breathe impressed with an IBM i utility that has effectively Run the enterprise with extremely mighty reliability, safety, and equipoise for 30-plus years, considering it’s her job to breathe certain the next 30 years of success.
Honesty is essential, Schmidt says, however compassion is additionally important. on no account lie, but don’t breathe overly blunt both, she says.
“It’s very vital to hold transparency in the groups, to construct miniature steps to net additional on,” she says. “but they also contemplate that RPG and COBOL developers feel a diminutive bit caught, and they’re frightened of extra transparency and the probability of coming into contact with technology they hold no view completely. It’s the job of the manager to breathe in a position to installation a crew-cherishing and group-valuing atmosphere within the team, so people don't suppose attacked.”

Building Portlets with IBM WebSphere(R) Portlet Factory 6.1.5
Pass 4 sure LOT-989 dumps | Killexams.com LOT-989 true questions | https://www.textbookw.com/
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 tender a recent challenge by introducing recent frameworks and APIs. To leverage existing assets and skills, WebSphere Portal supports the Struts Portlet Framework so Struts Web applications can breathe 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 industry 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 contemplate 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 method on the figure bean. If the validation fails, the control tide ends there.
If the Struts configuration file specifies action mapping then the appropriate action class 'execute' method is invoked with an instantiated figure bean as a parameter.
The Action may call other industry objects and repopulate the figure bean with the latest values and other industry 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 parade the page, the control tide ends by sending the output to the browser or if it's forwarded to another Action URI the above tide starts again.
AJAX in Action
AJAX is not a recent 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 soundless responds to each request, the way 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 exigency to change is updated, and that asynchronously.
Struts Portlet Framework Developers who hold undergo with the Struts Framework should appropriate 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, contemplate the Redbook IBM Rational Application Developer V6 Portlet Application progress and Portal Tools.
A portlet processes and renders differently than a servlet. A servlet will attain complete its processing in the service method, while the portlet will divide action processing and rendering into two separate 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 aspect there is a recent interface called IStrutsPrepareRenderer. For more details contemplate Executing Struts actions during the render aspect 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 contemplate the Portal Info Center.
Struts Portlets with AJAXThough AJAX isn't the prerogative solution for every Web application, there's increasing curiosity and enthusiasm among organizations to explore its benefits and contemplate how it works for their applications. AJAX isn't new, but it's complete on the client side and making it drudgery with different server-side frameworks is a challenge. This article is a result of my client undergo in developing Struts portlet applications with AJAX. In the sections above I briefly described Struts and AJAX. In the sections below I'll characterize 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 modest 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 illustration shown below.
As in device 5 and device 6, when the user clicks on the menu items, the right-side blue box items net refreshed without unloading the all page.
Below are some of the challenges they had and I'll explained how they addressed them.
Whatever the industry or company size, everyday industry processes require access to information resources such as data, applications and people. Providing access to complete necessary information resources in a cohesive and efficient manner can play a great Part in improving employee productivity, building successful relationships with partners and improving customer satisfaction.
IBM WebSphere Portal supplies an infrastructure to haul together access to information resources with a variety of formats. Access to complete necessary data, applications and people can breathe supplied in a lone Web browser interface. For a given process, access can breathe supplied to complete the resources required to complete the process. Existing data and applications can breathe leveraged and even integrated at the user’s screen. Content can breathe personalized based on a particular user’s role, and information overload can breathe minimized. Many information resources are soundless 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 haul together access to different information resources, it is likely that one or more of the required resources will breathe a green-screen application. The aptitude for a company to modernize and selectively and securely expand access to these green-screen applications in a portal environment can breathe a major requirement in creating a comprehensive portal solution for employees, partners, and customers.
IBM WebSphere Host Access Transformation Services (HATS) provides tools to back 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 possible to create an easier-to-use graphical user interface (GUI) for green-screen applications. Web services can also breathe created that provide yardstick programming interfaces to industry 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 back provide a comprehensive WebSphere Portal solution that will help employee productivity, collaboration with partners and customer satisfaction.
The industry Need
Basic needs common to running any industry embrace providing efficient means of obtaining information by employees, partners, suppliers, distributors and customers. Employees must hold effortless access to complete necessary information to breathe productive performing both job assignments and internal company processes such as human resource activities. Partners, suppliers and distributors must breathe 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 breathe able to research, order, receive and pay for products and services. The more efficiently information can breathe shared with these groups, the more productive and satisfied each group will breathe while interacting with the company.
In addition, as the requirements of managing the industry change, existing processes must breathe changed and possibly integrated with other, newer processes. To withhold the cost of change low, processes must breathe made more supple and re-usable as components within a industry system.
Businesses hold long used information technology (IT) systems to back help employee productivity, collaboration with partners, suppliers and distributors, and responsiveness to customers. Systems hold been built to maintain data and transactions necessary for doing industry 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 breathe necessary to complete a particular process.
A key factor in improving efficiencies while interacting with employees and external users is to provide a lone entry point and effortless access to the information resources necessary to complete industry processes based on the role of the halt user. Employees can become more productive with access to complete they exigency supplied to them in a lone Web browser interface. External users can breathe given security-rich, role-based access to complete the information they exigency to interact with the company and can attain 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 foreign and difficult to expend for many users. This interface is also not typically accessible by untrained employees or external users. To give recent 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 exigency to breathe rewritten or the access and interfaces to them exigency to breathe 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 lofty smooth of performance and reliability. Rewriting or replacing these applications can breathe 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 help the user interface to existing green-screen applications and construct 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, lone entry point and effortless access to complete the information resources they need. It is possible to customize what information you provide based on the role of the halt user. uphold for a credential vault makes it possible to simplify the process for halt users of signing on to multiple applications. Different portal pages can breathe supplied to back organize the tasks and processes that are made available.
Portlets, the visible lively components on a portal page, are used to provide access to different information resources. They back you control the tide and parade of information for the halt user. The click-to-action (C2A) feature allows you to partake data between portlets to integrate data and processes between different information resources. By providing users with cohesive and efficient access to complete the information they exigency in a Web browser interface, you can back help 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 possible to quickly and easily create portlets that will provide the necessary access. With HATS, a Web-like gape and feel can breathe created for your mission-critical green-screen applications without changing the applications themselves. An easy-to-use portlet interface can also breathe created that makes only necessary functions available to employees or external users and hides the rest. This is especially essential in a portal environment where the screen space is shared by many portlets.
