Hi all,

I have been trying to use the xtags library to do server side xslt with
Tomcat 4.0.1.  I keep getting a weird error when I try to use the parse tag.
I can break it with this jsp page:

================

<%@ taglib uri="http://jakarta.apache.org/taglibs/xtags-1.0"
prefix="xtags"%>

<xtags:parse>
  <root/>
</xtags>

================

When I hit the jsp page I get this error:

================

Apache Tomcat/4.0.1 - HTTP Status 500 - Internal Server Error

----------------------------------------------------------------------------

type Exception report

message Internal Server Error

description The server encountered an internal error (Internal Server Error)
that prevented it from fulfilling this request.

================

I suspect that this is the result of a misconfiguration on my part.  I have
tried a couple different versions of jaxp.jar and xalan.jar.  I am currently
using the xtags build from 2/20/2002.  Does anyone know what might be
causing this error, and how to resolve it?  I can tell that it is breaking
somewhere inside the xtags tag; if I use a page with just

	<xtags:parse/>

in it, it gives me a root element is missing exception.


Thank you in advance for any help,
Scott Boone
