JSF started its journey from version 1.0 and now it has come to the latest version of JSF is 1.2. The listing of versions released so far are :
There are many releases of 1.1 and 1.2 and these are listed below showing released date also:
The JSF specification was developed under the Java Community Process (JCP) as JSR 127, which released JSF 1.0 and 1.1, and JSR 252 which released JSF 1.2. The first release of JSF is JSF 1.0 in 2004. 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 release was bug-fixing. There were no specification or HTML renderkit changes. This version also works with same version of servlet 2.3 and jsp 1.2 as in the case of JSF 1.0.
JSF 1.1_01 release features bug fixes and performance improvements. Improvements include compression of views serialized to the client, failover support when storing views on the server, renderer fixes, and several other bug fixes and enhancements.It supports JDK 1.3.1 or later. Many bugs have been fixed so if your application depends on one of these bugs, it needs to be changed.
JSF 1.2 is the latest release and
it works with servlet 2.5 and jsp 2.1. If you want to run JSF
1.2 on Tomcat, you want 6.0 not 5.5. So
JSF needs a web container that supports atleast servlet 2.3 and jsp 1.2 and
these are part of J2EE 1.3.
New in JSF 1.2
In this section we will go through some new features and changes in JSF 1.2 specification. JSF 1.1 was designed for JSP 1.2 and so could not take advantage of newer JSP features and JSP could not be changed to fill the needs of JSF. This resulted in a number of new features and changes. For ex.
JSP 2.1 is developed under JSR-245 and JSF 1.2 is developed under JSR-252. These two groups have experts and they are working independently but the main focus of development was to provide more support and compatibility between these two technology that are powerful web presentation technology so that they can be useful for each other.
