JFreeChart with Servlet/JSP

[rajkanth]

Hi,

How to generate server side chart using JFreeChart. I would appreciate if some one could give me clue to do it using Servlet or JSP.

Thanks in advance,

rajkanth

I posed the question on JSP, but there is an excellent servlet war file package at http://www.jrefinery.com/jfreechart/index.html.
To use the servlet by itself, and not with the war package, you need to modify this in an import line (forgot which, but here is code)
and use this as a prototype.

//package com.jrefinery.chart.demo;

import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
import java.awt.image.*;
import java.io.*;
import java.util.*;
import javax.swing.*;

import javax.servlet.*;
import javax.servlet.http.*;

import com.sun.image.codec.jpeg.*;

import com.jrefinery.chart.demo.*;
import com.jrefinery.chart.*;
import com.jrefinery.chart.data.*;
import com.jrefinery.chart.ui.*;
import com.jrefinery.util.ui.*;

Now someone may ask: Where can I get a JSP/servlet engine to play with?
answer:
Resin -- www.caucho.com -- free for development
Tomcat -- jakarta.apache.org -- I recommend Tomcat 4. and tutorials at
http://www.onjava.com/pub/ct/33
Lite Web Server -- http://www.gefionsoftware.com/LiteWebServer/

If you later want to get into EJB, check out www.jboss.org

Thanks for the post Randy. Servlets and JSP are outside my area of expertise although I can understand why there is a lot of interest in using JFreeChart in this way.

If anyone would care to write up some documentation for this I'd be happy to post it on the website.
