I am trying to set this map data using java code ,
     HashMap procADMap1 = new HashMap(5);
               PropertyTypeWS pType = new PropertyTypeWS();
               pType.setTypeIndex(2);     
          AppdataDefImplWS appData1 = new AppdataDefImplWS();
          appData1.setName("Project");
          appData1.setType(pType);
          appData1.setMaxSize(400);
          appData1.setLOB(false);
     appData1.setDefaultValue("Project Default value");
          procADMap1.put(appData1.getName(), appData1);
          setVariableData("request","createNs","/createNs/namespaceData/appdataDef",procADMap1);     
Then I am passing request object to the method which I want to invoke from bpel process.
I am able to deploy the application but when I do post message I am getting following exception,
NamespaceWithMap (createNamespace) (faulted)
[2004/09/09 18:35:54] "{http://schemas.oracle.com/bpel/extension}bindingFault" has been thrown. Less
faultName: {{http://schemas.oracle.com/bpel/extension}bindingFault}
messageType: {{http://schemas.oracle.com/bpel/extension}RuntimeFaultMessage}
code: {Server.userException}
summary: {org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize.}
detail: {null}
Is there any other way to handle Map type in bpel process?
Thanks in advance,
Sanjay

Thanks for the quick reply.Actually the web service is already deployed on the server.What I want to do is use existing wsdl file of the deployed web service and invoke the method of the same using oracle PM.
If I remove element which uses apachesoap:Map type it just works fine also I am getting the complex object returned by the web service method.But when I try to set appDataDef which is of type apachesoap:Map(Axis conversion for java.util.Map and it uses namespace xmlns:apachesoap="http://xml.apache.org/xml-soap") I am getting the error.
Can you give me some direction to use this exising wsdl file to set map object or it is not possible.
