Hello everyone, I hope someone in this list can help me with this. 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 5.5.12 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
This is 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) I see JRE 1.5.0 contains an internal version of xalan and xerces and apparently I cannot override them. 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 - place the same files under [TOMCAT_HOME]/common/endorsed - place the same files under [JAVA_HOME]/lib/endorsed This is my very simple transformer page (very very basic): <%@ 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
