PM23491: A derived JAXB bean may not be marshaled (sent) correctly to a JAX-WS Web service.

APAR status

• Closed as program error.

Error description

• A derived JAXB bean may not be marshaled (sent) correctly to a
  JAX-WS Web service.  The receiving service may fail with an
  unpredictable error.
  
  Here is an example scenario that may fail.
  
  The method for the Web service is:
  
   @WebMethod
   @RequestWrapper(my.service.Echo)
   @ResponseWrapper(my.service.EchoResponse)
   public my.data.A echo(my.data.A a);
  
  And the application sends a JAXB bean that is my.data.B which
  extends my.data.A.
  
  In such cases, the JAX-WS runtime may send an XML message
  containing the element A instead of the derived element B.

  A derived JAXB bean may not be marshaled (sent) correctly to a
  JAX-WS Web service.  The receiving service may fail with an
  unpredictable error.
  
  Here is an example scenario that may fail.
  
  The method for the Web service is:
  
   @WebMethod
   @RequestWrapper(my.service.Echo)
   @ResponseWrapper(my.service.EchoResponse)
   public my.data.A echo(my.data.A a);
  
  And the application sends a JAXB bean that is my.data.B which
  extends my.data.A.
  
  In such cases, the JAX-WS runtime may send an XML message
  containing the element A instead of the derived element B.
  
  Note:
    1) The error will only occur in V7.0 if the Web method
  specifies a @RequestWrapper or @ResponseWrapper class.
    2) The error will only occur if the wrapper class was
  generated with tooling from a prior version of WebSphere.  The
  wsimport tooling provided in V7.0 adds @XmlSeeAlso
  annotations, which correctly reference the derived class (B).
  

Problem conclusion

• The JAX-WS V7.0 runtime uses the JAXB 2.1 version of JAX-B.
  The 2.1 version of JAXB provides an @XmlSeeAlso annotation,
  which is used to reference derived classes. The Feature Pack
  for Web Services runtime in V6.1 uses an older version of JAXB
  that does not support the @XmlSeeAlso annotation.
  
  This APAR will inspect the parameters of the Web service and
  tolerate the Feature Pack for Web Serice usage of derived JAXB
  objects.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 6.1.0.35.  Please refer to the Recommended Updates
