Re: problems in creating a web service

For example, if I have this java class

package javasoap.book.ch4;
public class MethodCounter {
   int _counter;
   public MethodCounter() {
      _counter = 0;
   }
   public int getCount() {
      return _counter;
   }
 }
I create a deployment descriptor file and an application like this to
execute the getCount method:

package javasoap.book.ch4;
import java.net.*;
import org.apache.soap.*;
import org.apache.soap.rpc.*;
public class GetCountApp {
   public static void main(String[] args)
      throws Exception {

      URL url =
        new URL(
          "http://localhost:8080/soap/servlet/rpcrouter");

      Call call = new Call();
      call.setTargetObjectURI("urn:CallCounterService");
      call.setMethodName("getCount");
      try {
         Response resp = call.invoke(url, "");
         Parameter ret = resp.getReturnValue();
         Object value = ret.getValue();
         System.out.println("Result is " + value);
      }
      catch (SOAPException e) {
         System.err.println("Caught SOAPException (" +
                         e.getFaultCode() + "): " +
                         e.getMessage());
      }
   }
}

Do you understand now what my purpose is? In my case I want to execute
servizio and composizione methods.

What exactly do you mean by "transform this software in a web service"?
What classes and/or methods to you want to access via SOAP?

How can I create the .dd file and the application file to transform this
software in a web service? Thanks for the help and excuse for the lenght of
the message
