DOMConfigurator.configure("log4j.xml");

Open in new window

That's a file name. You don't have a file. Try

DOMConfigurator.configure(StdClient.class.getResource("/log4j.xml"));

Open in new window

though that might be redundant

Incidentally it's not much use having that file inside a jar - as it can't be edited, but i understand it's easier for deployment. You should consider having the app write that resource as a file to the user's home directory. Then you can use your file-loading code
