I can not call EJB3 from another project

Question

I'm getting nervous not understanding how the ejb has to be called, since I'm getting errors with a simple example.

I have an EJB project called Test . It has only two classes: HelloWorldBean , HelloWorldInterface

    //HelloWorldBean 
package com.demo; 
import javax.ejb.Remote; 
import javax.ejb.Stateless;

@Stateless
@Remote(HelloWorldInterface.class) 
public class HelloWorldBean implements HelloWorldInterface {

        public String helloWorld() {
            return "Hello world !";
        } 
}

    //HelloWorldInterface  
package com.demo; 
public interface HelloWorldInterface {
            String helloWorld();
        }

Both are packed in a WAR called Test.WAR that has Test.jar inside, and it is deployed in the WAS 7.0 server.

I have another project called TestWeb that will be packed and deployed in the same server. Here I implemented a controller of the mvc.

package controller;
import javax.ejb.EJB;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class My_Controller {

    @EJB
    private HelloWorldInterface helloBean;

    @RequestMapping("testpage")
    public ModelAndView mostraPagina(){
        ModelAndView model = new ModelAndView();
        model.setViewName("testpage");
        model.addObject("hello", "? " + "EJB:" + helloBean.helloWorld());

        return model;
    }
}

I'm getting the errors in the following lines:

• private HelloWorldInterface helloBean;
• model.addObject("hello", "? " + "EJB:" + helloBean.helloWorld());

Edit: The error is:

HelloWorldInterface cannot be resolved to a type. Location: My_Controller.java

I created from the beginning a new ejb project and I chose to generate his client. After that, I create a session bean with the remote interface and I used the RAD option "expose the RPC adapter service" with the Web project. In this way I have two EARs both with two jars (including the client).

Roughly speaking:

• First EAR
  • EJB JAR, Client JAR
• Second EAR
  • Web JAR, Client JAR
