Thread: CALLING APPLET IN JSP

Hi,

I am creating pie chart using jfreechart , I am dynamicaly taking the values from DB and showing them in pie form. I have two java file one for database and other is for showing applet (applet class have main , which calls the DB class). All code properly works well in java. But I want these to be run through jsp. Could you please guide me how to move forward.

Thanks
Abhishek

Below is my applet .java file
-------------------------------------------------

package Pie_Chart;
 
import javax.swing.*;
import java.awt.Dimension;
import java.awt.GridLayout;
import javax.swing.JPanel;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.title.TextTitle;
import org.jfree.data.general.DefaultPieDataset;
import org.jfree.ui.ApplicationFrame;
import org.jfree.ui.RectangleEdge;
import org.jfree.ui.RefineryUtilities;
 
public class PieChart extends ApplicationFrame
{
 
private Object chart;
 
public PieChart(String title) {
 
 
super(title);
 
DB db = new DB();
db.dbConnect("jdbc:sqlserver://newinfomine:3468;instanceName=MSSQL2005", "eGActiveDB_762", "eGActiveDB_762" );
JPanel panel = new JPanel(new GridLayout(2, 2));
DefaultPieDataset dataset = new DefaultPieDataset();
DefaultPieDataset dataset1 = new DefaultPieDataset();
dataset.setValue("January "+DB.ravi_case, DB.ravi_case);
dataset.setValue("February "+DB.ravi_case_feb, DB.ravi_case_feb);
dataset.setValue("March "+DB.ravi_case_mar, DB.ravi_case_mar);
 
dataset1.setValue("January "+DB.pradeep_case, DB.pradeep_case);
dataset1.setValue("February "+DB.pradeep_case_feb, DB.pradeep_case_feb);
dataset1.setValue("March "+DB.pradeep_case_mar, DB.pradeep_case_mar);
 
 
 
 
JFreeChart chart1 = ChartFactory.createPieChart("Ravi Case", dataset, false, false, false);
JFreeChart chart2 = ChartFactory.createPieChart("Pradeep Case", dataset1, false, false, false);
 
panel.add(new ChartPanel(chart1));
panel.add(new ChartPanel(chart2));
panel.setPreferredSize(new Dimension(800, 600));
setContentPane(panel);
 
 
 
}
 
public static void main(String[] args)
{
PieChart demo = new PieChart("Pie Chart");
demo.setVisible(true);
}
 
}

I doubt this question has much to do with JSP, and more to do with deploying an applet. JSP simply generates html- the html is what needs to embed the applet. I don't see any html, or any problems, or any specific "this is what happens", so we can't really help you.

Edit- Now that I'm looking at your code, I don't even see an applet!

Theres getting you into the right direction

Bwah? An applet runs from the init() method, not the class file method name (you mean constructor?).

Lesson: Java Applets (The Java™ Tutorials > Deployment)

I see what you're saying. Yeah, the constructor is called first, where you should do any pre-loading and whatnot. Then its init() function is called, where you should actually start the processes. I guess for simple stuff it doesn't matter which one you use, but for more advanced stuff, you'll want to use that init function.

What? What do you expect to accomplish with that? Anyway, you're passing a Rectangle that is the whole screen into the createScreenCapture() method, so what did you expect to happen?

Like I said, you're going to need to post the HTML that your JSP is generating.
