Remy, The stack trace was caused because TC4 was installed in a path with spaces. After that I tried in a path without spaces and it still didn't work.
I think there's two bugs here. One is the URL's should be encoded, but two, I should never have come across the first bug because the classes are being searched for in the wrong location. The actual issue is that with RMI, the classloader is not using the java.rmi.server.codebase parameter to search for the class. The class is available for download in \Tomcat\webapps\app\com\..\...\???.class, but it is being looked for in \Tomcat\webapps\app\WEB-INF\classes and \Tomcat\webapps\app\WEB-INF\lib\*.jar. The client should be looking at http://server/app/com/../.../???.class and shouldn't get this exception: Caused by: java.security.AccessControlException: access denied (java.io.FilePermission C:\Tomcat\webapps\spweb\WEB-INF\- read) Try the test case that is attached to the bug. It shows this bug. I don't mind this being fixed after the first stable 4.1.x release, but I am unable to put any version of TC4 into production at the moment because of this. Hope this explains my problem a bit better. Cheers. Dave. Here's the stack trace (The bottom bit is the important bit). 21 Aug 2002 11:27:03,014 FATAL CriticalException - RMI failed: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling arguments;
