[Wicket-user] java.lang.NoClassDefFoundError with wicket.proxy.ILazyInitProxy in Weblogic 9.2

Scott T weaver Mon, 30 Oct 2006 14:19:42 -0800

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.

Regards,
