Eliminate Scriptlet condtions in JSP

Question

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";
else
    gotopage = /"pager.jsp?mymessage=proc";
RequestDispatcher dispatcher =
  getServletContext().getRequestDispatcher(gotopage);     
dispatcher.forward(request, response);
...JSP
<%
String mymessage = request.getParameter("mymessage")
if(mymessage.equals("err"))
     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");
%>I was thinking maybe a bean or regular Java class to handle this but not sure how. Here would be my method in a Java class:
public void getMessage(String msg)
     if(msg.equals("err"))
         out.println("Error on the page");
}Then I would put the method in a bean or what in JSP?
The Servlet would stay the same?

Answer 1

Put it in a bean or learn JSTL.
OR you could just put the message you want to display into page scope and have the JSP display it. Since the servlet already knows which page it's sending, let it figure out what the message should be, too.
no need for all that logic in the page.
do learn JSTL. Scriptlet code is very bad for maintenance.
