Hi guys i am having problems now that you may know about. I am calling xalan from a servlet running under orion which is working ok. However in the xslt stylesheet that i am running through xalan i call out to a java class using the xalan extensions mechanism. This xslt works fine when i run it though the commandline however when i run it under orion, xalan cannot find the class. The class is in the <my-app>/web-inf/classes directory (standard place for classes accessed by a servlet). I can see the class from the servlet that calls xalan but xalan throws a "ClassNotFoundException" when it trys to load the classes. Do you know where my classes need to be in this situation. I looked though the source of xalan an it seems to use the ContextClassLoader to load the classes. Does this conflict with orion's class loader. comments... regards peter
