Re: How do you pass data from a servlet to a jsp page?

[Bill Pfeiffer]

Are you using the request dispatcher to pass the servlet request to the jsp?
I do this all the time, setAttribute in the servlet (controller), call
forward() to forward the request to the jsp, and do request.getAttribute().

Servlet:

  RequestDispatcher rd;
  req.setAttribute("attr1", "hello");
  rd = getServletContext().getRequestDispatcher("jsp/MyJsp.jsp");
  rd.forward(req, res);

MyJsp.jsp:

<%= request.getAttribute("attr1")%>

HTH,
