I have a Servlet that checks for information and if there is an issue
it forwards the message to presentation page (JSP). Now I want to stop
using conditions in scriptlets in the JSP. Please advise how I can do
it in this situation in my Tomcat 4.1.27 container:

Servlet that forwards to JSP:

String gotopage = "";
if(mydata == 1)
     gotopage = /"pager.jsp?mymessage=err";
else if(mydata == 34
   gotopage = /"pager.jsp?mymessage=duper";
    gotopage = /"pager.jsp?mymessage=proc";

RequestDispatcher dispatcher =
dispatcher.forward(request, response);


String mymessage = request.getParameter("mymessage")

     out.println("Error on the page");
else if(mymessage.equals("dup"))
     out.println("Duplicate issue.");
else if(mymessage.equals("proc"))
     out.println("Process message issue");

Why not have the servlet store the long text in the request object
and have the JSP simply display it with a <%=whatever%> ?
