Java Tutorial - Java Scipt :

The TestUserEJB Servlet

The next step is to create a servlet that uses the UserDelegate class. The source code for the servlet follows:

import java.io.*;

import java.net.*;

import javax.servlet.*;

import javax.servlet.http.*;

import com.oldfriends.user.*;

import javax.ejb.*;

public class TestUserEJB extends HttpServlet

{

protected void doGet(

HttpServletRequest request,

HttpServletResponse response)

throws ServletException, IOException

{

PrintWriter out = response.getWriter();

UserDelegate ud;

try

{

ud = new UserDelegate();

UserDTO udata =

ud.getUserByUserid(“0000000-000000-00000000-0-00000000-1”);

out.println(“Hello:”+ud.getHello());

out.println( “Name:”+

udata.getFirstName() + “ “ +

udata.getLastName()+” “+udata.getUserid());

}

catch( Exception e )

{

e.printStackTrace(out);

}

}

}

Note that the servlet has no knowledge that the actual implementation of UserDelegate occurs via an EJB.
