JSP conditions

[chicago1985]

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. I dont have JSTL or EL due to restrictions in my environment.

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");
}
%>

Please advise.

Please advise.

You can straight away assign the message to be displayed to mymessage, instead of giving err or proc.
In the jsp u can display the msg by <%=mymessage%>
