HELP, Xalan and jstl 1.1 problem with transformer

[Valeria P.]

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="" /> <c:import var="xslText" url="" /> <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="" charEncoding="UTF-8" /> <c:import var="xslText" url="" 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     ---- Email.it, the professional e-mail, gratis per te:clicca qui Sponsor: Video-Corsi.com : Vuoi scoprire un modo rapido e veloce per imparare?
