Answer 1

JSTL is now part of EL.
It is not dependent on JSF implementation but depends on what servlet version your servelet container is compliant for.
So these must be running of different servers or different versions of same server.

Short answer is from 2.4 upwards which jboss 7 is .
If you go through JSTL doc here you will find out any way.

Check our JSTL wiki page: https://stackoverflow.com/tags/jstl/info You can get this kind of page whenever you hover the jstl tag below your question until a black box pops up and then click the info link.

It is true that Facelets 1.x and 2.x uses different namespaces for the JSTL tag library. It was less or more a namespace bug in Facelets 1.x and has been fixed for Facelets 2.x.

• The real JSTL 1.0 taglib uses the URI http://java.sun.com/jstl/core.
• The real JSTL 1.1/1.2 taglib uses the URI http://java.sun.com/jsp/jstl/core.
• Facelets 1.x uses the URI http://java.sun.com/jstl/core.
• Facelets 2.x uses the URI http://java.sun.com/jsp/jstl/core.
• Facelets 2.2+ uses the URI http://xmlns.jcp.org/jsp/jstl/core.

You can find all Facelets 2.x tags in the Facelets tag library documentation. Facelets don't ship with the full tag set as the real JSTL taglib. Only a few of the <c:xxx> and the full set of <fn:xxx> are copied into Facelets. The <fmt:xxx>, <sql:xxx> and <xml:xxx> tags are not taken over in Facelets.
