2. Introductions Your experience with portals? Have you used new Portlet 2.0 technologies? What do you want to gain from this session? 3. Who is Wesley Hales JBoss Portal Lead UI Architect Author of InfoQ article series: Developing Portlets using JSF, Ajax, and Seam JBoss Portlet Bridge project lead JSR-301 Expert Group member http://wesleyhales.com 4. Portals & Portlets What is a Portal? Windows that provide access to web applications and other information. Works across organizational boundaries to aggregate content coming from various web technologies: JSF, Seam, Struts, Wicket, PHP... 5. Portals & Portlets Portlets Are managed by a portal. Displayed via a Portal Page which is an aggregator of the portlet windows. A Portlet Application is also a Web Application. The Portlet Application may contain servlets and JSPs in addition to portlets. Portlets, servlets and JSPs may share information through their session. 6. Portlet Ajax vs. Regular (Servlet) Ajax Pitfalls with 1.0 portlet Action and render URLs point to the portal, not to the portlet you cannot make asynchronous calls to portlets through portlet URLs This results in the replaced markup being all the portal page markup not just the portlet window How we handle it Because a portlet is a Web application that can contain other resources, such as servlets and JSP pages, you can make the asynchronous requests to the resources that are bundled with the portlet. 7. Standard Portlet 1.0 Ajax 8. Ajax gets better with Portlet 2.0serveResource and Resource Urls With the newer (JSR-286) spec, we now have the serveResource() mechanism that makes Ajax easier. Makes it easy to migrate existing JSR 168 applications Works with existing client-side libraries Partial updates to the portlets UI 9. Portlet 2.0 Ajax 10. Portlet 2.0 Ajax Demo 11. Today's Ajax Component LibrariesWhat libraries are available to portlet developers? Do I have to use JSF? It is only framework (currently) with a spec backing itfor portlets. Two of the more popular libraries for JSF are: IceFaces Uses custom built bridge RichFaces Works with a JSR-301 based bridge 12. What is a Bridge, and why do we need it? There are different bridges to handle many different web applications. Wicket Seam Spring MVC JSF Struts PHP A bridge is often just a portlet. Recently the JSR-301 specication was formed to handle JSF in portlets which is much more than a simple portlet ;-) 13. Portlet Other component libraries, like IceFaces, provide their own quot;bridgequot; or way to handle the portlet and JSF lifecycles. 14. IceFaces Portlet Demo 15. IceFaces Portlet Markup 16. RichFaces Portlet The RichFaces component library runs under the JBoss Portlet Bridge, an implementation of the JSR-301 specication to support JSF within a portlet. 17. RichFaces Portlet Demo 18. RichFaces Portlet Markup 19. Portlet Bridge Summary Standards make life easier when investing in a portlet/Ajax/Component solution Currently the JBoss Portlet Bridge supports any combination of JSF, Seam, and RichFaces to run inside a portlet. It is currently in Beta 4 and should be approaching GA sometime in early '09 wen the spec is nalized. JSR 301 scheduled to be complete early 09 (168) 20. Mashups and OpenSocial Portlets Who is doing it? Are there any portlets available that make this easy? 21. QuickStart Portlet Demo 22. Questions?
