This is an old thread, but I just encountered the same issue and I've found something that might help.
My login module calls a web service to authenticate. I put the JAR for my LoginModule in default/lib and added an entry in login-config.xml for the security domain used by my web application. The LoginModule class itself is found and instantiated, but the web service classes through a NoClassDefFoundError. I added some debug statements and noticed that the thread context class loader is WebappClassLoader. I tried putting my JAR in the WEB-INF/lib folder of my web application, and got past the original error, but failed with a NoClassDefFoundError on one of the JAX-RPC classes (JAX-RPC libs are in default/lib). I suspect that if I also copied the JAX-RPC JARs into WEB-INF/lib it would actually work, but this isn't a very elegant solution (especially with multiple web applications). The Class Loading Use Case Wiki has a note at the bottom about needing to add specific use cases for WARs, since the WebappClassLoader is involved, and mentioned settings in jboss-web.xml that might influence how the WebappClassLoader delegates to JBoss's UCL. I couldn't find any details on those settings . . . does anyone have any ideas?
