how should/can I set up a test case??? Maarten
-----Oorspronkelijk bericht----- Van: Filip Hanik - Dev Lists [mailto:[EMAIL PROTECTED] Verzonden: vrijdag 10 maart 2006 18:16 Aan: Tomcat Users List Onderwerp: Re: classloader problem do you have a good test case for us, cause this shouldn't happen public Enumeration findResources(String name) throws IOException { if (log.isDebugEnabled()) log.debug(" findResources(" + name + ")"); Vector result = new Vector(); int jarFilesLength = jarFiles.length; -->this is line 946 the variable jarFiles is instantiated to (new JarFile[0]) when the webappclassloader is created. When it is stopped, jarFiles=null, becomes null. So your app is trying to load a class from the webapp after the webapp class loader has been stopped. Even if jarFiles got reset back to (new JarFiles[0]) upon stop(), you would get a ClassNotFoundException as there is nothing to load from. I'd be interested to see if this was reproducable, if so, open a defect and attach the test case.
