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 and the full set of are copied into Facelets. The , and tags are not taken over in Facelets.
