All session beans have a business interface, of course.

@Local
public interface MessageManager
{
   public void findMessages();
   public void select();
   public void delete();
   public void destroy();
}

From now on, we won't show local interfaces in our code examples.

Let's skip over components.xml, persistence.xml, web.xml, ejb-jar.xml, faces-config.xml and application.xml since they are much the same as the previous example, and go straight to the JSP.
