I use windows 7. I set the ClassPath like this:
D:\EclipseProjects\DLFWD_NEW\WebContent\WEB-INF\lib\jsf-api.jar;D:\EclipseProjects\DLFWD_NEW\WebContent\WEB-INF\lib\jsf-impl.jar;D:\EclipseProjects\DLFWD_NEW\WebContent\WEB-INF\lib\primefaces-2.2.RC1.jar
And I alse do this:
Window > Preferences > General > Content Types > Text > JSP > Add (xhtml)
But, it doesn't works.
When I use netbeans. I do nothing, but the autocomplete function works well.
