Coding the Application Client

When invoking the remote methods on the port, the client performs these steps:

1. Uses the generated helloservice.endpoint.HelloService class, which represents the service at the URI of the deployed service’s WSDL file:

   import helloservice.endpoint.HelloService;
   import javax.xml.ws.WebServiceRef;
   
   public class HelloAppClient {
       @WebServiceRef(wsdlLocation = 
         "META-INF/wsdl/localhost_8080/helloservice/HelloService.wsdl")
       private static HelloService service;

2. Retrieves a proxy to the service, also known as a port, by invoking getHelloPort on the service:

   helloservice.endpoint.Hello port = service.getHelloPort();

   The port implements the SEI defined by the service.

3. Invokes the port’s sayHello method, passing a string to the service:

   return port.sayHello(arg0);

Here is the full source of HelloAppClient, which is located in the following directory:

tut-install/examples/jaxws/appclient/src/appclient/

package appclient;

import helloservice.endpoint.HelloService;
import javax.xml.ws.WebServiceRef;

public class HelloAppClient {
    @WebServiceRef(wsdlLocation = 
      "META-INF/wsdl/localhost_8080/helloservice/HelloService.wsdl")
    private static HelloService service;

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
       System.out.println(sayHello("world"));
    }

    private static String sayHello(java.lang.String arg0) {
        helloservice.endpoint.Hello port = service.getHelloPort();
        return port.sayHello(arg0);
    }
}
