There is support for JSP taglib.

If you're seeing "unknown tag" errors, there might be a couple of reasons...

What type of project are you in? Are you in a web project?
How are you referencing your taglibs in your JSPs?

some examples:
<%// specified in web.xml file%>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>

<%// relative to WebContent folder %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

<%// relative to your JSP file %>
<%@ taglib uri="./struts-bean.tld" prefix="bean" %>

Actually, you don't "have" to change the web.xml file.

<%@ taglib prefix="test" uri="/WEB-INF/test.tld" %>

should work in your case (assuming you're in a web project)
note the leading "/" in the uri, this "should" resolve to the WebContent
folder.

Hopefully this solves your problem.

Well that is interesting, as I am having a real problem with WTP and JSP
taglibs. I have my taglib tags in an included JSP file, and while WTP
does things like content assist in the file that is included (the one with
the taglibs) it does not work and I get lots of yellow underlines about the
<c: tags in the including file. The one difference with what you have
written above is that I use TLDs included in the JAR files from the
WEB-INF/lib directory. So my taglib tag looks like:-

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

This works quite happily under Tomcat 5.5 (which is the server for this
project) and used to work with Lomboz under Eclipse 3.0 but does not work
with WTP 0.7 under Eclipse 3.1 (both GA).

Any thoughts?

Ignoring the web.xml for now, where is the test.jsp file located?
If it's not in the parent folder of WEB-INF, the uri value as-is
probably won't work.

Nothing strange going on like using the "c" prefix more than once?
Is the JSP located somewhere under the parent of your WEB-INF folder
that has the jar files?

Actually, bug 82333 has one lingering case where we fail to find the
TLD: uris beginning with '/'. Regrettably it wasn't fixed for 0.7.

Yes, c: is only used once (for the core JSTL tags) and the JSP is in
WebContent.

It works fine for me, so my only other guess is that there's
something related to how you're including the other file. Does the
file attribute of the include directive begin with a '/'?

I have tried both with and without, no change.
