Hi Erin,
thanks a lot for your reply.
Yes I am using 2.7.0 and in fact I already copied serializer.jar into the
endorsed directories (in both java and tomcat), but I am still receiving
that message.
I have read a lot of posts in various lists reporting the same problem but I
have never found a definitive solution. Someone told me that maybe there is
an incompatibility issue with Pluto libraries, but I tried tha same code
after stopping the applications that use Pluto and the error message was the
same.
Thank you,
Valeria

Hi Valeria,
Which level of Xalan are you using? If you are using 2.7.x then you would
also need to copy over serializer.jar into the endorsed directory.
Thanks.

SubjectXalan and jstl 1.1 problem with transform tag
Hallo,
I have this problem that I could not solve although I tried all the
suggestions I could find in manuals and in forums/lists archives.
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:
1) download the latest versions of xalan.jar, xercesImpl.jar and
xml-apis.jar and place them under the WEB-inf directory of my application
2) (just to be sure to override any existing old package including the same
classes) place the same files under TOMCAT_HOME/common/endorsed and
JAVA_HOME/lib/endorsed
3) add:
-Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp
.DocumentBuilderFactoryImpl
-Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl
-Djavax.xml.transform.TransformerFactory=org.apache.xalan.processor
.TransformerFactoryImpl
both to JAVA_OPTS and CATALINA_OPTS
I also tried the CheckEnvironment method and it appears I am running the
correct version of Xalan.
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 (very very basic as you can see):
<%@ 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>
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
