Async Call to BPEL

Question

I have a basic process, and trying to call it ansynchronously. The process works well when I invoke with the syncronous call, however it cannot get the input I provide ( a single string) with the asyncrounous call. For the error I see that the only difference between syncronous and the async one is the 'xmlns=""in the'most inner element of the XML (input). The namespaces are exaclty the same in both approaches, however the latter approach, which does not work, adds that namespace definition by its own. Is there a way to fix the problem?

Hi,
There is no exception printed on the BPEL Server console. The only error is being captured by the SOAP Monitor when it throws a SOAP exception.
However, when i tried to remove the WS Addressing information from the SOAP header, it works.
//super( SERVICE_NAME, PORT_TYPE , OPERATION_NAME , SOAP_ACTION, STYLE, SERVICE_PARAMETERS, messageID, replyTo);
super( SERVICE_NAME, PORT_TYPE , OPERATION_NAME , SOAP_ACTION, STYLE, SERVICE_PARAMETERS,null,null);
I am very interested to know how you manage to invoke the process as well as handling the callback from the process. If possible could you share your codes with me.
Also I'm quite suspicious about my BPEL and WSDL scripts. Maybe the problem lies in these 2 files only. Can anyone help to verify if there is anything i need to do for the callback portion to work?
