Hi Joerg, It seems to only be a problem when I use it under Tomcat. I'm running Tomcat 4.1.27 on win 2000. I've put the xalan, xerces, and xmlapis jars in the tomcat endorsed directories, but still get this error and end up with a blank page. I tried it with Jetty tho and it works fine, so I guess it's a classloader issue with Tomcat?
