Now we need to add a business method and mark the interface as a remote one with @Remote annotation.

package sampleear;

import javax.ejb.Remote;

@Remote
public interface RemoteBusinessInterface {
    public String sayHello(String name);
}

...

Implement the business method sayHello and mark the class as a stateless session bean with the @Stateless annotation.

@Stateless
public class MyStatelessSessionBean implements RemoteBusinessInterface {

    public String sayHello(String name) {
        return getClass().getName() + " says hello to " + name + ".";
    }
}

...

Right click on the SampleWAR project and select New -> JSP. Name it index.jsp and click Finish.

Change it so it executes the servlet upon form submission.

Right click on the SampleWAR project and select Properties. Go to Java Build Path and click "Project"item, then click "Add" button to select the "SampleEJB" project and click OK.
- Or select Properties, choose Deployment Assembly. Choose the Manifest Entries tab, then Add..., then Finish, Apply, OK.
Right click on the SampleWAR project and select New -> Servlet and fill it in with the following values:
Section
Java Package: sampleear
Class name: MyServlet
Click Next.

Change the URL Mapping section so the servlet serves at /sayHello url mapping and click Finish.

MyServlet.java opens up automatically for editing after creation, update the servlet as shown below to call off the ejb when executed.
