In this post i will show the HTML5 Support given by JSF 2.2, Which is part of Java EE 7 Spec. Also how to integrate the Bean Validation 1.1 feature with help of CDI (Contexts and Dependency Injection) 1.1 spec. Before going the HTML5 support, my earlier posts on JSF, i used @ManagedBean annotation, because its part of Managed Bean Specification (Java EE 6). Another Reason i used Tomcat as a primary container, if i used Managed Bean Spec then its part of Mojjara implementation, so no need to add more CDI specific (Jboss Weld lib) lib to class-path. But from Java EE 7 on-wards, JCP community expand the CDI capabilities and make CDI as important spec in Java EE 7 and Managed Bean spec is deprecated in favor of CDI . so they recommend to use CDI wherever its possible. so our future all post to target the CDI. next post i will show how add the CDI capability to tomcat container.

Recently Java EE 7 specification goes into final. Next week (June 12) oracle going to release the Java EE 7 specification and Glass Fish 4 as reference implementation to general availability. Java EE 7 adds more features like JSF 2.2, Servlet 3.1, Json Processing, websocket support, etc.. click here about the spec. In this post i'm going walk through in JSF 2.2 JSF 2.2 is added more features, and JSF as  a main presentation layer of Java EE platform. compare to JSP, jsp is not getting more feature, they just add maintenance release.

This is Third  part of JSF 2.0 discussion. Please visit  part one   and part two Update : New Post JasperReports in JSF In this post we will discuss JSF with AJAX. In JSF 2.0 gives full support for ajax integration in web application.  With Ajax, web applications can send data to, and retrieve data from, a  server  asynchronously (in the background) without interfering with the display and behavior of the existing page. so with help of ajax we will make more interactive page.   JSF 2.0 Faclets provide <f:ajax> tag for achieve ajax in web application without writing client side java script ajax code. JSF 2.0 takes care all of this. JSF and ajax integration is one of the greatest feature. and no other framework provide this much easy ajax integration in web application. Consider we have one simple web application it prompt the name and click submit button its display the nam...

This is Second  part of JSF 2.0 discussion. Please visit   part one   Update :  New Post JasperReports in JSF In JSF 2.0 part 1   post, i used  @ManagedBean annotation for POJO java class. Its OK, actually it derived from JSF 1.2.But we should use @Named annotation instead of @ManagedBean, if CDI  ( Contexts and Dependency Injection ) environment is available. I used Tomcat 7, its not Java EE 6 server and by default CDI is not available.  But we can use JBoss's Weld lib for achieve  CDI in tomcat with minimal configuration. Weld is reference implementation of CDI and its comes standalone version also. This standalone version weld provide CDI environment for both Web Application and Java SE application. By default Glassfish 3.0/3.1 server comes with weld  library for CDI Environment. Here i am using Glassfish server with CDI enabled. Page Navigation ...

Java Server Faces (JSF) is one of the presentation web frameworks in java. There is lots of others frameworks like Spring, GWT, Wickets, Struts. Today this post we ll discuss why JSF is more important then others.Here I am not  criticize any frameworks. i just talking about JSF.   In JSF 1.2 and previous version of JSF used JSP as a view declarative language and JSP life cycle is not matched with JSF and ajax requests. JSF 1.2 are complex to use and they have some short coming in feature. But JSF 2 is completely changed the adapt lots of technologies, but still its support backward compatible.Its very easy to learn. More over JSF is center piece in Java EE 6 Spec. It means that what are the new components or specification introduced in Java EE 6 are seamlessly integrated into JSF. Because those components spec is designed for JSF in mind.

Update : I put new post for  Why should I learn JSF                   I put new post for  Understanding Java Server Faces 2.0  Part  2   JavaServer Faces (JSF) is a Java-based Web application framework intended to simplify development integration of web-based user interfaces.  Java Server Faces (JSF) 2.0 is a improved component of Java EE 6 Specification.  Its Component based model. Its is alternative technology for Struts, JSP, Spring. Its MVC (Model-View-Controller) based architecture.
