  was not considered in the Feature Pack
  for Web Services fixpacks.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Application Server            *
  *                  users of JAX-WS web services                *
  ****************************************************************
  * PROBLEM DESCRIPTION: A NullPointerException may occur when   *
  *                      JAX-WS web services marshall JAX-B      *
  *                      fields annotated with @XmlElementRef.   *

  * RECOMMENDATION:                                              *
  ****************************************************************
  When a JAX-WS web service marshalls a JAX-B object, a
  NullPointerException may occur. The JAX-B field in question is
  annotated with an @XmlElementRef, which was not considered in
  the Feature Pack for Web Services.
  
  An exception like the following may be seen:
  
  javax.xml.ws.WebServiceException:
  org.apache.axis2.jaxws.wrapper.impl.JAXBWrapperException:
  java.lang.NullPointerException
  javax.xml.ws.WebServiceException:
  org.apache.axis2.jaxws.wrapper.impl.JAXBWrapperException:

  at
  org.apache.axis2.jaxws.ExceptionFactory.makeWebServiceException

  ...
  

Problem conclusion

• The web services code was updated to consider the
  @XmlElementRef annotation when marshalling JAX-B fields.
  
  The fix for this APAR is currently targeted for inclusion in
  fixpack 6.1.0.23.  Please refer to the Recommended Updates
