Hey Owen,
		Thanks a million for pointing that out Owen. A rookie
mistake on my part but I would've been stumped. 

Thanks again,
Mark.

Mark,

You appear to be iterating over the names of the output parts and
printing out information about each name rather than the value for each
part. Try:

if (successful)
{


    Iterator outIter = output.getPartNames();


    while (outIter.hasNext())


    {


        String nextName= (String) outIter.next();


        nextObj = output.getObjectPart(nextName);


        System.out.println(nextObj.getClass());


        System.out.println(nextObj.toString());


    }


}



Regards,
Owen

Sorry folks I hit send by accident when trying to format the message.
*************************************

Hi Folks,
            I'm fairly new to WSIF but I created a WSIf client for a
JBOSS session bean. In the WSDL that describes the service it clearly
indicates that the type is that of xsd:double. Therefore I was expecting
the type of the object to be of type java.lang.Double when I extracted
it from the output message. Unfortunately it is extracted as type
java.lang.String.



WSIFServiceFactory factory = WSIFServiceFactory.newInstance();


WSIFService wsifService =
factory.getService(wsdlLocation,serviceNS,serviceName,portTypeNS,
portTypeName);


WSIFPort wsifPort = wsifService.getPort(portTypeName);


WSIFOperation wsifOperation = wsifPort.createOperation(operation);


WSIFMessage input =wsifOperation.createInputMessage();


WSIFMessage output=wsifOperation.createOutputMessage();


WSIFMessage fault =wsifOperation.createFaultMessage();


input.setObjectPart("in0","0407114");


boolean successful =
wsifOperation.executeRequestResponseOperation(input,output,fault);


Object nextObj = null;


if (successful)
{


    Iterator outIter = output.getPartNames();


    while (outIter.hasNext())


    {


        nextObj= outIter.next();


        System.out.println(nextObj.getClass());


        System.out.println(nextObj.toString());


    }


}





The result of this is that the class is java.lang.String and the object
is some decimal value which is correct except for the object type. I've
tried this in the past with plain DII apache soap with the following
code and it returned the result correctly.


**************************************************************


String endpoint = "http://localhost:8080/jboss-net/services/FPG"


Service service = new Service();


Call call = (Call) service.createCall();


call.setTargetEndpointAddress(new java.net.URL(endpoint));


setCallAttributes(call);


invokeServiceCall(call);


System.out.println("Call made to "+component_name+" service");


String methodName = "orderFPGTest";


call.setOperationName(methodName);


MessageContext ctx = call.getMessageContext();


Message msg = ctx.getRequestMessage();


System.out.println("The call looks like\n"+call.toString());


call.addParameter("name"
,org.apache.axis.Constants.XSD_STRING,ParameterMode.IN);


call.setReturnType(org.apache.axis.Constants.XSD_ANY);


Object res = call.invoke(new Object[] { "0407114" });


System.out.println("ClassType is " +res.getClass());


double result = ((Double)res).doubleValue();


**************************************************************


This produced an object of type java.lang.Double as opposed to
java.lang.String.


Here's the WSDL for the message.


  - <wsdl:message name="orderFPGTestResponse">
    <wsdl:part name="orderFPGTestReturn" type="xsd:double" />
  </wsdl:message>
  - <wsdl:message name="orderFPGTestRequest">
    <wsdl:part name="in0" type="xsd:string" />
  </wsdl:message>


Does anyone have any idea why this is happening that the WSIF is
returning a java.lang.String object and the regular apache soap API
returns the correct java.lang.Double?


Thanks,
Mark.


P.s. Apologies for the first message.
