How can I call one web service from another web service (inside the same WAR)

Context: Application Server - Glassfish 3.1.2. JavaEE JAX-WS Technology. IDE - NetBeans 7.1.1.

I created 2 web services starting with WSDL using wsimport. Also there is no EJB. They both use the @WebService annotation . They both live in the same WAR (not sure if this should be true, but maybe). I can deploy and test both services very happily individually, using SOAP-UI as a client.

Now I want WebService1 to call WebService2 at runtime. I don't want to just call implance webservice2 with java (locally, so to speak). I would call webservice2 correctly, like webservice, to create a looser connection.

In the IDE, I can generate the required code to call webservice using the provided function "generate code: web service". This added @WebServiceRef (wsdlLocation = "WEB-INF / wsdl / servicename.wsdl") and some code to create a port and invoke the target web service.

    // Call Web Service Operation
   Identity port = service.getIdentityPort();
   String req = "";
   javax.xml.ws.Holder<StructureMessageHeader> idHeader = new javax.xml.ws.Holder<StructureMessageHeader>();
   String result = port.getIdentifier(req, idHeader);

This compiles fine, but at runtime it fails. Deployment is successful, and the services are both generally happy individually (unless you call this code), but when one web service tries to call another, I get

ClientTransportException: The server sent HTTP status code 404: Not Found.

More details below.

Does anyone know why this might happen? Where am I wrong? What did I miss?

Any help is very valuable.

The best way to approach this is to make the web service a layer that then invokes the application logic. Then, when one set of business logic needs to call another set, it does not need to go through unnecessary http roundtrip traffic. Think using something like Spring with @Service and @Autowired. In the EJB world (and I know you said you weren’t using this), this is done using @Local interfaces and @EJB session injection, so you don’t go through a huge remote API stack just to call a method in another class.
