Error: Class org/w3c/dom/Node violates loader constraints

[Krysty Sullivan]

Hi! I made use of Xalan-Java 1.2.2 from xml.apache.org (I needed to use it to process XPath expression) in my J2EE application running in Allaire JRun and it worked well, but when I migrated the application to WebSphere Application Server 4.0, it returned an error "Class org/w3c/dom/Node violates loader constraints" . How do I solve this? It seems that it is associated with the Xalan-Java 1.2.2 package (jar files) because everytime I remove the XPath part which uses the Xalan-Java package, I don't get the error anymore. It's weird because it runs in JRun but in WAS 4.0, it doesn't. Thanks!

Hey Krysty, did you ever figure this one out? I've got exactly the same problem in WebSphere 4.x. My app runs in TomCat just fine, but dies in WebSphere the the same error you described.
