i dont know if its the best way to do..but i have done it the following way
Called BarGraph.jsp in a html in thus
<img src="BarGraph.jsp?choose=<%=strTable%>">
BARGRAGH.JSP
<%@ page language='java' %>
<%@ page import="java.sql.*,cv_classification.*
,java.awt.*,java.awt.image.BufferedImage,com.sun.image.codec.jpeg.*,java.app
let.*,java.util.*" %>
<%
//The graph is going to be an image in JPEG format, so we'll need to set the
correct MIME, or content type.
//The browser uses the MIME type to decide how to display the response.
//The following code sets the MIME type:
response.setContentType("image/jpeg");
//The Java 2D API supplies the BufferedImage class,
//which provides a way to store and manage pixel data in memory.
BufferedImage bi = new
BufferedImage(NLP_Constants.WIDTH,NLP_Constants.HEIGHT,
BufferedImage.TYPE_INT_RGB);
Graphics2D g = (Graphics2D)bi.getGraphics();
g.setPaint(Color.white);
// set up the Graphics2D context by calling the createGraphics() method:
ServletOutputStream out0 = response.getOutputStream();
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out0);
encoder.encode(bi);
