Coding the 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.

   HelloService service = new HelloService();

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

   Hello port = service.getHelloPort();

   The port implements the SEI defined by the service.

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

   String response = port.sayHello(name);

Here is the full source of HelloClient, which is located in the tut-install/examples/jaxws/simpleclient/src/java/ directory.

package simpleclient;

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

public class HelloClient {

    public static void main(String[] args) {
        try {
            HelloClient client = new HelloClient();
            client.doTest(args);
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

    public void doTest(String[] args) {
        try {
            System.out.println("Retrieving the port from
                     the following service: " + service);
				 HelloService service = new HelloService();
            Hello port = service.getHelloPort();
            System.out.println("Invoking the sayHello operation
                     on the port.");

            String name;
            if (args.length > 0) {
                name = args[0];
            } else {
                name = "No Name";
            }

            String response = port.sayHello(name);
            System.out.println(response);
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
}
