Encountered an unknown type while processing 'xslt' attribute

Hi,

I'm just trying to transform an XML document using the XML tags in JSTL 1.1. I'm using Tomcat 5.5.7 as my web container and JRE 1.5. Here's my jsp:

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

<c:import var="zzzz-Instance" url="forms/zzzz-Instance.xml" />
<c:import var="zzzz-XHTML" url="forms/zzzz-XHTML.xml" />
<c:import var="zzzz-XSL" url="xslt/zzzz-jsp.xsl" />

<x:transform var="zzzz-Full" doc="${zzzz-XHTML}" xslt="${zzzz-XSL}" />

<x ut select="$zzzz-Full/*" />

When I access this jsp, I get the following error on Tomcat:

javax.servlet.ServletException: <transform> encountered an unknown type while processing 'xslt' attribute
org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl .java:846)
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.j ava:779)

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:245)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
....

We've used the other JSTL 1.1 tags (i.e. functions, fmt, etc.) with no problems, so I don't think this is a setup problem. The XML and XSL files are well formed XML files... So what's going on here?

Thanks.

I see that this one was asked a while ago, but I ran into the same problem recently. So, just to help others, I found that the problem for me was the name of the variable that I was storing the xslt result in was bad. It contained a '-' which was not a problem for jstl, in general, but the xml jstl tag library doesn't like it.

So, you would have to change:

Thanks for the follow-up, Eric. In this case I would say "better late than never" definitely applies!

(I'm linking this thread to the XML forum as well in case somebody decides to search there for this problem.)
 
I agree. Here's the link: http://aspose.com/file-tools
