Sending information from Java to Java script?

Question

I've been trying to send information from Java to Java script using the JSObject but i keep receiving a java.lang.ClassNotFoundException: com.sun.deploy.appcontext.AppContext exception i'm using netbeans 7.1.

Here is the full stack trace

java.lang.NoClassDefFoundError: com/sun/deploy/appcontext/AppContext
    at MapTest.MapApplet.init(MapApplet.java:23)
    at sun.applet.AppletPanel.run(AppletPanel.java:434)
    at java.lang.Thread.run(Thread.java:722)
Caused by: java.lang.ClassNotFoundException: com.sun.deploy.appcontext.AppContext
   at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
   at java.net.URLClassLoader$1.run(URLClassLoader.java:355)
   at java.security.AccessController.doPrivileged(Native Method)
   at java.net.URLClassLoader.findClass(URLClassLoader.java:354)
   at java.lang.ClassLoader.loadClass(ClassLoader.java:423)
   at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308)
   at java.lang.ClassLoader.loadClass(ClassLoader.java:356)
   ... 3 more

It is referring to this line of code

    win = JSObject.getWindow(this);

These are all my imports

import netscape.javascript.JSObject;
import java.lang.*;
import java.applet.*;
import java.awt.Graphics;

I really need help with this can't seem to find solutions anywhere.

Thanks.

How are you testing your Applet? JSObject is not supported in Appletviewer. — Perception

I came across a similar error and was able to solve it by adding deploy.jar found in the local Java install to the project build path. Not sure how to do this in netbeans but for others using maven you can try adding the folowing dependency:

<dependency>
    <groupId>sun</groupId>
    <artifactId>deploy</artifactId>
    <version>7.0</version>
    <scope>system</scope>
    <systemPath>${java.home}/lib/deploy.jar</systemPath>
</dependency>
