I have developed a JSP webapplication with an Applet. I am not able to display the applet from my JSP page.

I have developed a JSP webapplication with an Applet. I am not able to display the applet from my JSP page.

Below is the code:

<applet codebase="http://localhost:8080/av_applet_jsp/applets" code="av_app.class" WIDTH="200" HEIGHT="100">

av_app.class is located inside Webcontent/applets/

Where I am going wrong?

Here is my applet class:

public class av_app extends Applet {

    @Override
    public void paint(Graphics g) {
        int inset;
        int rectWidth, rectHeight;
        g.setColor(Color.pink);
        g.fillRect(0,0,300,160);
        g.setColor(Color.green);
        inset = 0;
        rectWidth = 299;
        rectHeight = 159;
        while (rectWidth >= 0 && rectHeight >= 0) {
            g.drawRect(inset, inset, rectWidth, rectHeight);
            inset += 15;
     开发者_Python百科       rectWidth -= 30;
            rectHeight -= 30;
        }
    }
} 

I am able to see applet using applet viewer. What I am doing wrong in my JSP page?

When I tried an example code it's working:

<applet codebase="http://java.sun.com/applets/NervousText/1.1"
    code="NervousText.class" width=400 height=75>
  <param name="text" value="Welcome to HotJava!">
</applet>


With a codebase of..

http://localhost:8080/av_applet_jsp/applets

..and code attribute of..

av_app.class

..the JVM will be looking for the class in..

http://localhost:8080/av_applet_jsp/applets/av_app.class

OTOH you state the applet is actually located at..

http://localhost:8080/Webcontent/applets//av_app.class

Either move the class to where the applet is expecting to find it, or change the HTML to look where it is located.


problem was i also mentioned package name in the class ,after removing its working fine ,thnkx for the answers guys

What happens when you browse to http://localhost:8080/av_applet_jsp/applets? Is your class file there?

On another note, it appears that you did not package your applet as a JAR. Why not?
