Re: soap with proxy

[Martin Gainty <mg...@hotmail.com>]

Good Morning All-
What is the best way to debug and see whats happening on the Server side of 
a  Soap service?

BTW If I go to the provided endPoint listed as 
http://localhost:8080/axis/services/MessageWebServiceWS I am displayed
MessageWebServiceWS
Hi there, this is an AXIS service!

Perhaps there will be a form for invoking the service here...

//If I setup a call something like

     java.util.List list=null;
        Object results=null;
        Service service = new Service();
        try
        {
         Call call = (Call) service.createCall();
   System.out.println("Just before call.setTargetEndpointAddress(new 
java.net.URL(endPoint))");
         call.setTargetEndpointAddress(new java.net.URL(endPoint));
//OperationName
         call.setOperationName(method);

         String[] tokens = word.split(",");

         list = java.util.Arrays.asList(tokens);

         if(call.isParameterAndReturnSpecRequired(new QName(method)))
         {
         for (int x=0; x<list.size(); x++)
         {
                tokens = list.get(x).toString().split("=");

                String Fieldname       = new String(tokens[0]);
                String Fieldname_value = new String(tokens[1]);

                determineFieldname(Fieldname,Fieldname_value);

//              QName qNameType = new QName("MessageWebServiceWS","string");
                QName qNameType = new QName("string");

                QName QualifiedFieldname = new QName("MessageWebServiceWS", 
Fieldname);

                call.addParameter(QualifiedFieldname, qNameType, 
java.lang.String.class, ParameterMode.IN);
      } //end for

//        call.setReturnType(XMLType.SOAP_ARRAY);

     } //end isParameterAndReturnSpecRequired(QName operationName) returns 
true

        Object parameters[] = new Object[]{"String1","String2"};
        for (int x=0; x<list.size(); x++)
        {
          System.out.println("parameter:"+x+" is = 
"+parameters[x].toString());
        }
        //results =
        call.invokeOneWay(parameters);

     } //end try...
     catch(javax.xml.rpc.JAXRPCException jax_rpc)
     {
           System.out.println("Indide MessageWebServiceClient 
JAXRPCException has been thrown message = "+jax_rpc.getMessage());
     }

It seems the server side is not operational??

The scope attribute in the deployment descriptor specifies whether the scope 
is request, session or application.  For request scope, a separate instance 
of the service class is created for each request, so there is no 
synchronization issue for instance methods, but there can be for class 
(static) methods.

There is also session scope, in which one instance of the service class is 
created per session, and application scope, in which one instance of the 
service class is created to handle all requests.  The latter is most common. 
In that case, one must be very conscious of synchronization.  Most SOAP 
calls are implemented in a stateless manner, and synchronization is not 
required, but if you have instance variables, etc., that are accessed by 
multiple threads concurrently, you must be worried about synchronization.
