Hi,

  Have a look into the sample code .. Refer some urls in mapserver  portal
"how to compile  mapserver with java".But basically I m not java developer.I
am  into C#.net.May the below sample can help you at least it guides you.

<%@page contentType="text/html; charset=GB2312" language="java" %>

<%@page import="edu.umn.gis.mapscript.*" %>

<%@page import="java.util.Iterator, java.util.ArrayList"%>

<%@page import="java.util.Date"%>

 {

  System.out.println("!ok");

 }

 else

 if(request.getParameter("rodio")!=null)

 {

  if(request.getParameter("rodio")!="")

  {

   rodio=Double.parseDouble(request.getParameter("rodio"));

  }

 }

 rectObj ro=map.getExtent();

 double xw=ro.getMaxx()-ro.getMinx();

Subject: [mapserver-users] Using JSP with ms4w

Hi
I am new to this mapserver thing and cant figure out how to work with JSP
instead of PHP for my GIS application development.I already have Tomcat 6
installed and its working fine. Tell me how to configure it so that it will
work with ms4w.Please also suggest some tutorials and examples for me to
start working.
