The earlier version of JSF is 1.0 and now it has come to the latest version of JSF is 1.2. The listing of versions released so far is given below:-

1. JSF 1.2 (11 may 2006) - Latest release of JSF specification.
2. JSF 1.1(27 may 2004) - Bug fix release with No specification changes and HTML render kit changes but performance improvement.
3. JSF 1.0 (11 mar 2004) - Initial release of JSF specification.

JSF 1.0 supports Servlet 2.3 and JSP 1.2. After JSF 1.0, JSF 1.1 was released. The main purpose of this was to solve the problem of bug-fixing. There were no new specification or HTML render kit changes. This version was also compatible with same version of Servlet 2.3 and JSP 1.2 as in the case of JSF 1.0.

JSF 1.1_01 release has developed features for bug fixes and performance improvements. Improvements include compression of views serialized to the client, failover support while storing views on the server rendered fixes. It supports JDK 1.3.1 or later.

JSF 1.2 is the latest release and it works with servlet 2.5 and JSP 2.1. If we want to run JSF 1.2 on Tomcat then we need 6.0 not 5.5. So JSF needs a web container that supports at least Servlet 2.3 and JSP 1.2 and these are part of J2EE1.3.

Features of JSF 1.2

• Unified Expression Language (EL):- The unified EL has been added to JSTL for solving the problems when integrating with JSP EL with the help of JSF EL.


• Support for AJAX i.e. Asynchronous Java Script and XML file


• Issues related with navigation button on Multi Frame or Multi Window Faces Apps.


• Giving XML schema Support for XML config files.


• Better Security Support Features and java script validation.

All the examples are developed with the latest release of JSF 1.2.
