Forwarding from Servlet to JSP

I am trying to implement the MVC2 model. I have a Servlet that fetches data from a session bean and forwards the entity from the servlet to a jsp:

public class MyServlet extends HttpServlet{

@EJB UserFacade userFacade;  

//Fetch the user from the session bean  
Users currUser=userFacade.find(userName);  
...
request.setAttribute("user", currUser);  
getServletContext().getRequestDispatcher("/index.jsp").forward(request, response);  
}

in index.jsp: I get the user from the request, and I can print its name if I use scriptlets tags, but when I use EL nothing is printed: 

<@page import="Entities.Users">  
 <"Users currUser = (Users)request.getAttribute("user");">  
 <= currUser.getName() > -OK!  
 ${currUser.name}-Nothing is printed!

How should I include/forward the session-bean into the JSP in order to be able to use EL (and avoid using scriptlets)?
Is this the preferred way to implement the Model View controller?

EL uses request attributes. You don't have currUser as request attributes. If you try ${user.name} it will work.

I'm not sure what you mean by "session bean". EJBs are session beans, but you didn't show anything about it in the view. But anyway - EJBs should not be accessible in the view.

In short - you are using the correct approach - just use EL with the attributes that you've set.
