6) Restart your server and run given jsp code.
<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%@ page import="org.jfree.data.*" %>
<%@ page import="org.jfree.chart.*" %>
<%@ page import="org.jfree.chart.plot.PlotOrientation"%>
<%@ page import="org.jfree.data.jdbc.JDBCCategoryDataset"%>
<%
String query="SELECT * from chart";
JDBCCategoryDataset dataset=new JDBCCategoryDataset("jdbc:odbc:student","sun.jdbc.odbc.JdbcOdbcDriver","","");
dataset.executeQuery(query);
JFreeChart chart = ChartFactory .createBarChart3D(
"Test",
"Id",
"Score",
dataset,
PlotOrientation.VERTICAL,true, true, false);
ChartFrame frame1=new ChartFrame("Bar Chart",chart);
frame1.setVisible(true);
frame1.setSize(350,450);
%>
Here student is our dsn and chart is table.
