Yeah, I had come to the same conclusion, I was just hoping someone would be Johnny on the spot with an “Oh, I had that same exact issue and I did…” I just deployed the app in Tomcat and it works fine there as well *sigh*. So, I guess I will be dissecting WLS’ classloader tomorrow, oh joy. Thanks anyways :-)

Do you know what class it tries to proxy there?

NoClassDefFoundError mostly means that the ILazyInitProxy can be found but something its need doesn't
But that is an interface that doesn't have any exotic things in it.

Hello,

I am using wicket-spring-1.2.2 and wicket-spring-annot-1.2.2 to provide for dependency injection in my Wicket app. Everything works without a hitch in Jetty. However, I just recently started testing the app in our test servers. The test servers are running Weblogic 9.2, and I am getting a "java.lang.NoClassDefFoundError: wicket/proxy/ILazyInitProxy" error in one of my pages.

The closest thing that I could Google up regarding this were issues regarding the possibility of an older CGLIB (currently using cglib-nodep-2.1_3.jar) jar being in that classpath somewhere else (found this on the Hibernate support forums and no I am not using Hibernate). Unfortunately, the server admin found neither traces of either a CGLIB jar nor any net.sf.cglib.* classes anywhere. Other pages are using the injection just fine, so I am unsure of what is causing this one page to bomb.
