  2. 168 Tutorial-Handling the PortletRequest PortletResponse Cyc
    Duration: 7:50

    Description: This CBT tutorial looks at how to create JSR168 deployable portlets that handle the common request-response cycle. The full size, full resolution tutorial can be seen here: The portlet itself is very simple, but it is also very effective, and it demonstrates both how similar portlets can be to typical Servlet and JSP programming, while at the same time introducing you to how applications can get internationalized, i18n and i10n. It does this by creating a CountrySnooperPortlet. Check out the tutorial and Java portlet code examples. As a note, the portlet is fully JSR-168 compliant, and as such, can be deployed to any JSR168 portal server, including WebSphere Portal Server, JetSpeed, Pluto, LifeRay, Plumbtree, OpenPortal and more! Check out my Hibernate tutorials and SCJA mock exams at: http

  3. Action Processing in a JSR168 Portlet: WindowStates Tutorial
    Duration: 6:53

    Description: You can find the original, high resolution video tutorial at: You can also find links to purchase my JSR168 Portlet Programming Book. :) Action Processing in a JSR-168 Portlet Strictly speaking, the various do methods of a portlet should only be responsible for generating the markup that needs to be sent back to the client. Since portlet mode methods, such as doView, doEdit, doConfigure and doHelp, are really only intended for generating the markup that gets sent back to the client, those methods are said to be part of the portlet?s rendering phase, and as such, these methods are passed a RenderRequest and a RenderResponse object. Two Phase Portlet Processing Tasks such as state management, form handling and PortletSession management should not take place during the portlet rendering phase. In fact, certain tasks, such as the manipulation the PortletPreferences object associated with the doEdit mode, or forcing a portlet to display itself in a maximized state, simply can?t be performed during the portlet rendering phase. Such tasks must be performed before a portlet is asked to render itself, during an important stage known as the event processing or action processing phase. The event processing phase is associated with a special method called processAction. This portorial examines how to take advantage of the action processing phase of a portlet.

  4. How to Display an Image in a Java Portlet JSR168: A Tutorial
    Duration: 8:59

    Description: The original, high resolution, full screen video can be seen at (Just follow the link at the top of the page for Portlet Tutorials and Examples) This tutorial, which comes with both a video and the accompanying Java Source example code, shows you how to develop a JSR-168 compliant portlet that uses a Java Server Page (JSP) to display an image. Displaying an image in a portlet isn't as easy as displaying an image in a normal JSP or a Servlet. You need to encode the namespace, and make sure you are linking to the right location in the portlet war. If there are any errors. the portal page aggregation process will not locate your image, and you may end with not found errors on your client page, or at the very least, errors in your log files. This tutorial will help you learn hot to propertly display gif and jpg images in a portlet window, and help you avoid any problems or PortletException objects. For the full resolution CBT tuturial, go to (that's my Hibernate and JPA tutorials site) and click on the link at the top for Portlet Tutorials. (There's also a bunch of links for free, mock certification Java exams for getting Sun certified. Check those out, along with my associated books on the topic) And if you really liked this tutorial, don't be afraid to buy my book on JSR168 Portlet Development and Programming.

  6. PortletSession APPLICATION_SCOPE: 168 Portlets Sharing Data
    Duration: 9:04

    Description: The full screen video, in full resolution, can be seen here: ApplicationScope and the PortletSession An interesting aspect of the PortletSession is the fact that data stored in the PortletSession, by default, is local and accessible only to the portlet that created it. By default, data stored in the PortletSession by one portlet cannot be shared by any other portlets on the same portal page. If there are four portlets on a portal page, if they all use a PortletSession object, then each one will have a separate, unshared, PortletSession namespace. Even if two instances of the same portlet appear on a portal page, each one will have its own, unshared, PortletSession namespace. PortletSession and the PORTLET_SCOPE This default behavior is known as PORTLET_SCOPE, and has been the way the PortletSession object has behaved for years. However, developers have done nothing but moan and groan about the fact that it is incredibly difficult to share information between portlets that exist within the same portlet application (think war file), so, with the JSR-168 portlet specification, the Java Gods introduced the concept of a shared, APPLICATION_SCOPE, for the PortletSession. When a portlet shoves an object into the PortletSession, and specifies APPLICATION_SCOPE as the visibility of the data, any portlet that is part of that same portlet application, can obtain that data by providing the appropriate key when making a call to the PortletSession?s getAttribute ...

  11. PortletSession: How to Manage Portal User State Programatically in doView
    Duration: 6:52

    Description: Managing State with the PortletSession To view the full screen, high quality and resolution CBT video, go here: If the user is going to be good enough to provide information to us through html forms and http headers, the least we could do is keep track of that information, if only for the duration of the user?s visit to our site. To provide a stateful experience for portal users, portlet developers rely upon the services of the PortletSession, which, by the way, is remarkably similar to the HttpSession object from the Servlet API. The PortletSession is easy to use, and helps maintain a stateful experience for the user, overcoming the stateless nature of the HTTP protocol. This tutorial takes a look at how to use the PortletSession to manage Please support our site, link to us, buy some books, and remember: Happy Java! PortletSession session = request.getPortletSession(); Check out my mock exams at my Sun Certification site: For a great Portlet and Hibernate development book, go here: This tutorial uses IRAD but deployment can go to any JSR168 standards compliant portal application server, including WebSphere, JetSpeed, Pluto, BEA, OpenPortal, LifeRay, Oracle, Sun, IBM, apache and more!

  12. JSPs & Portlets: Forwarding to a JSP from doView in JSR168
    Duration: 7:01

    Description: Part 1 of this 2 part tutorial demonstrates how to forward to a JSP, Java Server Page, from a JSR-168 Portlet. The full tutorial can be viewed here: This link also provides the Java Source code, deployable war for JetSpeed/Pluto/WebSphere/LifeRay/OpenPortal, etc. In a good model-veiw-controller type of application, a Java centric component should never be polluted with lots of lousy html. With typical servlet and struts based applications, html is usually generated by a Java Server Page (JSP); in this regard, portlet applications are no different. However, portlet applications do present some unusual complications when deferring to a JSP for markup generation. How does a JSP link back to a specific portlet on a page? How does a portlet call a JSP? How do we gain access to the portlet specific PortletRequest and PortletResponse object in JSP? This tutorial deals with basic JSP development, and the issues that present themselves when deferring to a JSP for markup generation. Please support our site, link to us, buy some books, and remember: Happy Java! public class JSPDisplayPortlet extends GenericPortlet { protected void doView(RenderRequest request, RenderResponse response) throws PortletException, IOException { response.setContentType(request.getResponseContentType()); String url = "/welcome.jsp"; getPortletContext() .getRequestDispatcher(url).include(request,response); } For Hibernate3 & JPA Tutorials and Sample Code: www.thebookonhibernate ...

    Duration: 7:04

    Description: Check out my actual website for the full screen, high resolution video: Standard JSR 168 Portlet Modes Any preliminary look at the portlet API will demonstrate a major similarity between portlets and servlets. Both portlets and servlets handle the request-response cycle, both are Java centric components, and both have access to the J2EE runtime environment. But there are some major differences between portlets and servlets as well. One of the most significant ways portlets are different from regular servlets is their support for various modes, namely view, edit and help. When it comes to portlet modes, there is no applicable analogy to typical servlet and JSP programming. This tutorial will look at the various modes available to the portlets you create, and how a developer can programmatically take advantage of these modes. Breaking Away from a Portlet as a Servlet Mentality Handling a request-response cycle is the most fundamental aspect of portlet programming, but inspecting a request and sending out a response to the client through a portlet is by no means revolutionary. After all, request-response programming is exactly what we do in a Java servlet. Let?s compare a Portlet to a Servlet: instead of a doView method, a Java Servlet has a doPost or a doGet method. Instead of being passed a PortletRequest or a PortletResponse object, a Java servlet is given an HttpServletRequest and HttpServletResponse object. In many ways, handling the request ...

  14. Portlet Encode NameSpace: How to Encode a Portal NameSpace
    Duration: 6:20

    Description: For the original tutorial, please look follow the portal tutorials link at the top of my webpage on Hibernate and JPA development. Thanks! This tutorial demonstrates how to, and best practices surrounding, the display of images in a JSP page, namely a Java Server Page that is part of the page aggretation process of a Portal Server. Encoding Form Data with getNamespace( ) To ensure that form data being sent from our portlet to the server doesn't get confused with the form data of another portlet, the RenderResponse object gives us a special method called getNamespace(); this method will return a unique, alpha-numeric character set that uniquely identifies a portlet on a particular page. If we use the getNamespace() call, and attach that identifying String to each data element being sent back to the server, no other portlet on the portal page will mistakenly use our portlet's data. All form elements should be encoded using the getNamespace() method of the response, and all fields being read in a portlet should assume the field has been namespace encoded. Note For simplicity sake, this book will use examples that exclude the namespace call, which is fine for training, but is completely unacceptable in development or production. Uniquely identify all of your form data, or JavaScripts, by using the getNamespace call to uniquely encode their names. For mock Sun certification exams and free online Java tests, check out:

    Duration: 4:40

    Description: This exercise shows how to create the widget of a view, by using the JSR-286 standard. Remember that Denodo also allows other standards for portlets to be exported. In the video you will see how to install the widget in the Liferay application and how to use it in a page. Make sure the Liferay portal is running on a known port before attempting this exercise. Click on "new" next to "Widgets" in the Publish section of Virtual Dataport, as shown in the Tutorial Exercise video above. Expand project Default, and click on client_with_bills_complete view. Click OK, and notice that Denodo offers us a choice of WAR file types to export. Select JSR-286, and ensure that the connection parameters for Denodo are correct: URI: //localhost:9999/admin User: admin Password: admin Click OK, then after the export has completed, click OK again. Start up the Liferay portal and login as an administrative user and look for the Liferay admin toolbar along the top of the home page. Click Manage - Control Panel, and select Plug-Ins Installation. Click "Install More Portlets..." and then "Upload File", and then the "Browse" button. Denodo exports WAR files to the following subdirectory: %DENODO_HOME%\resources\apache-tomcat\webapps\export But you can also enter the web browser URL localhost to display a file listing of these .war files -- this gives you the ability to transport them from their default location to any local or shared drive you wish.

  16. Saving Data in the PortletSession: Managing Portal State JEE
    Duration: 8:11

    Description: This tutorial takes the NumberGuesserPortlet one step further by adding PortletSession functionality so that the number of guesses the user has performed to try and guess that magic number is counted. This is a very simple piece of extra functionality, but it is very effective. The portlet tutorial is created with IRAD, but the deployed war file is fully JSR168 compliant, so it can be deployed to any portal server, be it LifeRay, Pluto, JetSpeed, WebSphere Portal Server (WPS), Oracle, BEA Weblogic, OpenPortal or any other 168 compliant portal server on the market. *** Man, have I ever been busy. People seem to love free, online, mock exam simulators. I put together a bunch of free online exams to promote my Sun Certified Java Associate (SCJA) books, and people have been just bugging the life out of me to create some similar online tests for the IBM Portlet Development certification exams 399 and 829. Well, I've managed to do it, and they're online now. There are five different exams, with fifteen questions each. That's 75, free, online exam questions!!! Seriously, when you get all rich and successful, please don't forget about me. I've actually sorta cheated on the exam link names. I've listed them on the links tab as being on five different subjects. That's a bit of bait and switch, because each of the mock exams is a mish-mash of different test 399 topics, including testing, debugging, JSR168 API concepts, C2A (Click-2-Action), WebSphere Portlet Services, Struts and JSF ...

    Duration: 5:30

    Description: This tutorial demonstrates how to get a Portlet to link back to itself within a JSP or even with the HTML code spit out within the doView method of a Portlet. The key is the PortletURL object... The full video CBT tutorial, along with Java code, downloadable source and sample portlets, and the full resolution vid, can be seen here: Programming portlets presents the web developer with many new challenges, not the least of which is figuring out how to invoke a particular portlet from an html form. A portlet can be placed on a variety of different web pages at runtime. How can we invoke a web-based resource when we don?t know the web address of the page on which it will appear? Another challenge is making sure that the data submitted through our form goes to our portlet, and our portlet only. We don?t want other portlets on the page using data submitted from our form. Fortunately, the portlet API addresses these very challenges. The Challenge of Linking Back to a Portlet When a user clicks the submit button on a form, there must be an object sitting on the server that is ready to process the user?s request. With typical Servlet/JSP applications, form submissions are forwarded to a servlet, and the name of the servlet is specified as the action of the form; however, we can?t do that with a portlet. This tutorial looks at the PortletURL object (formerly the PortletURI), and how it can be used to link back to a portlet running on the portal server ...
