JSP 2.0: probs w/ JSTL and jsp:doBody

[Timo --Blazko-- Boewing <bl...@neveprise.net>]

Hello List,

Currently i am trying JSP 2.0 w/ Servlet 2.4 under Tomcat 5.0.12. One of
the things i love the most is tag templates for usage in WEB-INF/tags.
I use current Apache JSTL 1.1 w/ up to date Struts on Debian GNU/Linux
and J2SE SDK 1.4.1_02.

However, as soon as i have JSTL in a JSP page and in between my tags
that have jsp:doBody in it OR when i have tags w/ jsp:doBody and e.g. a
c:forEach in the body (the JSP, not within tags, that works pretty much.

Here an example:

test.jsp --------------------------------

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="my" tagdir="/WEB-INF/tags/" %>

<my:simple caption="${param.cap}">
   <c:forEach items="${aHashMap}" var="entry">
      <li>${entry.key}</li>
   </c:forEach>
</my:simple>


simple.tag --------------------------------

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

<h1>${caption}</h1>
<ul>
   <jsp:doBody />
</ul>


I have read much docs, including Sun's JSP 2.0 current proposal, but
cannot guess what the solution might me. I think it has to do w/ current
JSP context, but have no idea how to fix this or if this is possible at
all. One workaround is to avoid jsp:doBody and split the tag into two
files, e.g. <my:simple caption="x" / >[JSTL here]<my:simpleEnd />, but
that is somehow not nice...

The exceptions i receive look like these.

Thank you for any hints!

Timo
