jar -tf yourJar.jar

2. Re: JAAS LoginModule NoClassDefFoundError
maniarkm Jul 21, 2005 4:48 AM (in response to maniarkm)The class file is in the jar. I have made sure of that.
However, I am confused. How can I access other files in the same jar but not find this one? -
3. Re: JAAS LoginModule NoClassDefFoundError
jesse_sweetland May 5, 2006 1:01 PM (in response to maniarkm)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?
Thanks,

jesse_sweetland May 5, 2006 1:18 PM (in response to maniarkm)Followup:
I copied the JAX-RPC stuff into WEB-INF/lib and the LoginModule works, but now I get linkage errors all over the place in the web application proper (specifically from JBPM stuff, which is deployed as a SAR in default/deploy).
Short of copying the world into WEB-INF/lib, is there any way to resolve this class loading issue?
