I have Eclipse Version: 3.6.2. In my JSP's I have the following taglibs

<%@ taglib uri="//java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="//java.sun.com/jsp/jstl/functions" prefix="fn" %>

Eclipse shows a error
"Cannot find the tag library descriptor for "//java.sun.com/jsp/jstl/core"

And i have few c:when and c:if tags. Eclipse shows
Unknown tag (c:when).

Can anyone please let me know how to get eclipse working for JSTL tags.

Thanks
Clint

These tags come out of JAR you do not have. You'll have to figure out
which one, where to get it, etc.

Unless the h t t p : were stripped from the post, does it work when you
Run the page On Server? You didn't mention whether it worked at runtime
or whether you just had put the directives in a JSP.
