APAR status

• Closed as program error.

Error description

• When using JAX-RPC web service programming model, if the binding
  style is set to RPC/Literal binding type, and an array type is
  used in a parameter of the request message, then the response
  message will be wrong

Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Application Server V8.5       *
  *                  users of RPC/Literal binding type for web   *
  *                  service call, with an application that has  *
  *                  an array type in a request or response      *
  *                  message.                                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: You get an empty array when you input   *
  *                      a string and output a string array      *
  *                      with RPC/Literal binding type.          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When JAXBContext was created initially, no array type was on
  the list. This is to gain performance in most cases.
  

Problem conclusion

• When Marshalling and Unmarshalling is happening the engine
  will check input and output parameters. If an array type
  is needed it will rebuild the JAXBContext with array type
  support. This is a good balance between function and
  performance.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.2.  Please refer to the Recommended Updates
