I've writen two clients to access Google and Amazon Web APIs, After recieving the Response
I get the following Exception.
-------------------------------------------------------------------------------------------------------------------------

         Key: AXIS2-23
         URL: http://issues.apache.org/jira/browse/AXIS2-23
     Project: Axis2
        Type: Bug
  Components: om  
 Environment: Windows XP sp1,
    Reporter: L.P.Gayan Asanka
 Assigned to: Davanum Srinivas 


Hi All,

I have built a programs to access Google Web API and Amazon Web API via AXIS2. The operation
is ‘doGoogleSearch’ in Google WSDL and ‘search’ in Amazon WSDL, I can set the number
of search results that should be included in the response message. In Google When the number
of results is 1 or 2 it is working almost properly, But when the number of results are getting
higher (that means the SOAP msg is big) I am getting an exception. When the results count
is 10, most probably this exception is thrown. In the case of Amazon, the exception is always
thrown. This programs worked with M1 successfully.

I guess the problem is with OM and Stax, I hope your aid to solve this problem.

Exception thrown is:-

this is part of the code in my ClientCallbackHandler that process the SOAP envelope:-

            result.getResponseEnvelope().serialize(writer);
            //part.serialize(writer,false);
            writer.flush();

        } catch (XMLStreamException e) {
            System.out.println("Error occured after responce is received");
            e.printStackTrace();
        } catch (FactoryConfigurationError e) {

            e.printStackTrace();
        }

        operation = body.getFirstElement();

        String opLocalName = operation.getLocalName();
        if (opLocalName.equals("Fault")) {
