Subject [jira] Created: (AXIS2-2313) JAXBBlockImpl block object is already consumed on client trying to deserialize 2 holders and 1 return string
Date Mon, 12 Mar 2007 18:13:09 GMT
JAXBBlockImpl block object is already consumed on client trying to deserialize 2 holders and
1 return string
------------------------------------------------------------------------------------------------------------

                 Key: AXIS2-2313
                 URL: https://issues.apache.org/jira/browse/AXIS2-2313
             Project: Axis 2.0 (Axis2)
          Issue Type: Bug
            Reporter: Davanum Srinivas
         Assigned To: Rich Scheuerle


When the client gets back a response, it throws a "JAXBBlockImpl block object is already consumed"
exception. Reason is in RPCLitMethodMarshaller aorund line 348, we use MethodMarshallerUtils.getReturnElement
to get back the return string. but then line 368, we call MethodMarshallerUtils.getPDElements
and try to unmarshal the other 2 holders. So we get an exception saying that the block is
already consumed.

thanks,
dims
