Hello, here's an interesting one: after sucessfully deploying my application and accessing the startup page, all requests for servlets yielded the following error 500 Internal Server Error Servlet error: Error instantiating servlet 'wcfsystem' (servlet class not found, make sure it exists at D:\home\workspace\webcomponents\test\webapp/WEB-INF/classes/com/itsit/wcf/ad aptor/WCFServlet.class, in a jar in D:\home\workspace\webcomponents\test\webapp/WEB-INF/lib/, in an orion-web.xml specified classpath or global server classpath) Strange thing, the class files reside exactly at the location mentioned in the error message (under WEB-INF/classes). After tampering for 3 hours with ANY configuration item I could find, i finally decided to disregard the error message because something else had to be hindering the class loading process. My candidate: one of the jars in the lib directory. After removing xerces.jar, everything indeed worked fine (somewhat). Obviously, the orion code had internally caught an exception, dropped it and reported a generic - and misleading - error. My request: correct and comprehensive error reporting is extremely important, especially in a complex setup such as a J2EE server, and even more when there is so little additional documentation as with orion. Orion may be superior in features and runtime performance, but weaknesses such as these can be QUITE costly for us (maybe) customers, as I pointed out in an earlier post. Of course, I would like to know what the problem with xerces was/is. And lastly, one more question: How do I enable user authentication? I think I have done everything given in the servlet 2.2 spec, but I get no login dialog (BASIC auth), nor are my forms called. Christian Sell
