Weblogic 12c - JAX-WS NPE

Question

I'm using Weblogic 12c. After migrating from Weblogic 11g to 12c, web service started to throw the following error. (Application is deployed successfully, the error is threw at every invoke)

Answer 1

I had the same problem with WebLogic 12.2.1.3.0 and it was caused because I had enabled DebugEjbInvoke logging.

• Environment -> Servers -> AdminServer -> Debug
  • weblogic -> ejb -> invoke: DebugEjbInvoke --> Disabled solved the issue

My stacktrace:
java.lang.NullPointerException at weblogic.ejb.container.internal.BaseWSLocalObject.__WL_preInvoke(BaseWSLocalObject.java:85)
