axis2 web service calling another web service

[arseny levin]

I have a "big picture" question: Can my web service call another web service?
I am using axis2 as my platform for running the services.
It goes something like this:

package service.first;
public class FirstService{

public String getWelcomeMessage(){
   RPCServiceClient  serviceClient  = new RPCServiceClient();
   Options options = serviceClient.getOptions();
   EndpointReference targetEPR = new EndpointReference("http://localhost:8080/axis2/services/SecondService");
   options.setTo(targetEPR);

   QName op = new QName("http://second.service/xsd", "getHello"); 
   Object[] opArgs = new Object[] { };
   Class[] returnTypes = new Class[] { String.class };
        
   Object[] response = serviceClient.invokeBlocking(op, opArgs, returnTypes);
        
   String result = (String) response[0];

   return (result + "stranger!");
   
}

and the second service:

package service.second;
public class SecondService{

public String getHello(){
  String hello = new String("Hello");
  return hello;
 }

}

At this point one would expect, assuming both services are up and running, calling FirstService.getWelcomeMessage() would return "Hello stranger".
I mean I have another RPCServiceClient invoking "getWelcomeMessage" over the web.
What I get is an exception on the server side (which is running both of the services).
I can post the exception and log itself, but this isn't really a technical question, but rather "can I do that?". (It could be that each service object in axis i srunning in some sandbox
and it's thread (if any) has all kind of weird limitations... I wouldn't know.)
Please help!
