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.

package sampleear;

import javax.ejb.Stateless;

@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.
