    Default Java/Javascript

    I wanna create a simple Java/javascript applet.

    I mean: An Java-applet who can call a javascript function in his html document.

    HTML-document:
    Java Code: 
    <html>
<head>
<script type="text/javascript">
function theJFunction()
{
 alert("Hello world");
}
</script>
</head>
<body>

<applet code="myApplet" width="500" height="500"></applet>
</body>
</html>
    Applet:
    Java Code: 
    public class myApplet extends java.applet.Applet
{
 public void init()
 {
  //here to call the javascript function "theJFunction()"
 }
}
    How can I call the javascript function from my applet?

    I've allready seen that document but when I do
    Java Code: 
    getAppletContext().showDocument
        (new URL("javascript:doAlert(\"" + msg +"\")"));
      }
    The page goes to another URL, I mean the browser thinks the page goes to another URL.
    And than I can't use the javascript command "onbeforeunload".

    For the JSObject I don't have the libraries, and I can't find where to download them.

    In order to start using JSObject you need to import netscape.javascript.JSObject
    Add plugin.jar to the classpath of you project, netscape is there.
    Plugin.jar can be found in jre6 folder
