You can also use RESTful services:

Answer 2

Thanx all for your suport . . i have got the answer for my question.
i created a restfull web service using Jersey and called it using the following code in my gwt app engine application:
ClientConfig config = new DefaultClientConfig();
Client client = Client.create(config);
WebResource service = client.resource(UriBuilder.fromUri("http://localhost:8080/de.vogella.jersey.first").build());
String obj=service.path("rest").path("bye").accept(MediaType.TEXT_PLAIN).get(String.class);
and the web application code is :
package de.vogella.jersey.first;
import javax.ws.rs.*;
#Path("/bye")
public class Hello {
// This method is called if TEXT_PLAIN is request
#GET
#Produces(MediaType.TEXT_PLAIN)
public String sayPlainTextHello() {
return "Hello it worked";
}
