Support JAX-RS 2.0 with WebLogic 12C

Question

I am reading the following links to get weblogic suported Jaxrs 2.0

https://docs.oracle.com/middleware/1213/wls/WLUPG/upgrade_ws.htm#WLUPG332 https://docs.oracle.com/middleware/1213/wls/RESTF/use-jersey20-ri.htm#RESTF297

I have found javax.ws.rs-api-2.0.jar file renamed it javax.ws.rs-api-2.0.war. Then deploy it as a library file into weblogic.

But I am still having the error since weblogic still use jaxrs 1.1 APIs.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'openStackService': Invocation of init method failed;
hodError: javax.ws.rs.core.MultivaluedMap.addAll(Ljava/lang/Object;[Ljava/lang/Object;)V

here is my all configuration:

I have realized that weblogic 12.1.3 comes with following foldes having jax-rs-2.0.war

Oracle\\wlserver\\common\\deployable-libraries.

I have installed the war file as library into Application Server
