While I am trying to access webservice url from GateIn3.4(JBOSS AS 7) it is redirecting toorg.exoplatform.services.rest.impl.ResponseImpl$ResponseBuilderImpl and the following error occurs org.exoplatform.services.rest.impl.ResponseImpl$ResponseBuilderImpl.<init>(ResponseImpl.java:217). I am attaching the entire log here.

When I am running the code in a sample progrm it is working fine. But the issue happens when executing from within the application which is deployed in gateIn 3.6 with JBOSS7. Is any other configurations should I do ?Or can it be due to some jar mismatch?
