JAX-WS Web Services and Eclipse Dynamic Web Project

Question

I saw several tutorials on the web about creating web services, but If I look at the Eclipse Dynamic Web Project structure it seems to me that there should be a kind of "build-in" way to create those web services

So, is there a tutorial specific for adding web services to an existing Dynamic Web Project and that will end up showing them under JAX-WS Web Services folder (indicated by the arrow in the image above)? Thanks!

Answer 1

Those should be populated if the module contains a JAX-WS web service.

To see an item show up under Service Endpoint Interfaces, create a Java interface which is annotated with javax.jws.WebService:

package org.example.sampleservice;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface SampleService {

    @WebMethod
    String sayHello(String name);
}

Produces:

To populate the Web Services tree, create a web service implementation class. Note this example implements the service endpoint interface; this is not a technical requirement. In other words, you can populate one and not the other. Only this step will actually produce a functional web service implementation within the module (and the eclipse UI you mention):

package org.example.sampleservice;

import javax.annotation.Resource;
import javax.jws.HandlerChain;
import javax.jws.WebService;
import javax.xml.ws.WebServiceContext;

@WebService(endpointInterface = "org.example.sampleservice.SampleService")
@HandlerChain(file="handlers.xml")
public class SampleServiceImpl implements SampleService {

    @Override
    public String sayHello(String name) {
        return "Hello, " + name;
    }

}
