My application is referencing _wl_cls_gen.jar which is created in temp folder by weblogic12c, it is not part my build. How to eliminate it? I am using Spring framework and Hibernate
that's is created when it is deployed a war/ear file into WLS.
however it shouldn't be a problem. Probably you are trying to access some files from your app.
you can deploy an expanded war file or use tag at weblogic to access files
