HELP, Xalan and jstl 1.1 problem with transformer

You should send this email to the Tomcat mailing list as well since this
is a known problem with TOMCAT (with JDK 1.5) rather than with Xalan.

HELP, Xalan and jstl 1.1 problem with transformer

Hallo everyone,
I am new to this list. I browsed through it several times though and I
really hope someone here can help me.
I know that a lot of people have had the same problem but I could not find
a solution to it, although I tried all the suggestions I came across.

I developed a simple XML based document repository using JSTL xml tags 1.0
under Tomcat 4.0.
Now I am trying to do the same with Tomcat 5 using JSTL 1.1 but I keep
receiving an error message about the instantiation of the transformer:

javax.xml.transform.TransformerFactoryConfigurationError: Provider
org.apache.xalan.transformer.TransformerImpl could not be instantiated:
java.lang.InstantiationException:
org.apache.xalan.transformer.TransformerImpl
I did the following to overcome the problem:
- download the latest versions of xalan.jar, xercesImpl.jar and
xml-apis.jar and place them under the WEB-inf directory of my application
- (just to be sure to override any existing old package including the same
classes) place the same files under tomcat-home/common/endorsed

Other details about my test environment:
- Windows XP
- JRE 1.5.0
- Tomcat 5.5.12
- A CMS compliant with Tomcat 5 and coming with JSTL 1.1 libraries
(InfoGlue: www.infoglue.org)

This is my very simple transformer page (identical to the many examples
you find everywhere on the net):

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/xml" prefix="x" %>
<c:import var="xmlText" url="${requestScope.xmlUrl}" />
<c:import var="xslText" url="${requestScope.xslUrl}" />
<c:catch var="ex">
<x:transform xslt="${xslText}" doc="${xmlText}"></x:transform>
</c:catch>
<c:if test="${not empty ex}">
<c:out value="${ex}" />
</c:if>
i also tried with:
<c:import var="xmlText" url="${requestScope.xmlUrl}" charEncoding="UTF-8"
/>
<c:import var="xslText" url="${requestScope.xslUrl}" charEncoding="UTF-8"
/>
fearing that maybe the error was due to encoding, but the result was the
same.

The request-scoped variables contain what they should (I tested them
importing directly to the page without storing the imported contents in
variables).

I really don't know what else to try.

Thank you to those who had the patience to read and to those who will be
so kind to reply...

Valeria
