 In Axis2 you can write your service impl class with Axiom and get this
 working. I mean you can write your service impl class as below

 class MyService {
   public OMElement getData(OMElement value){
 // do the processing here
  }
 }

 Thanks

(http://marc.info/?i=418E552C.2020002%20()%20hp%20!%20com), but I
think that they would have similar solutions.

(NOTE:  I realize that this violates SOA principles because of the
looseness in what the service is delivering.  However, this is for a
demo, rather than a final version and the finished product will have a
tighter schema.)

Thank you,
JC
