I don't know of any way to force the browser's VM to load the newer JFC classes. As far as I know, you have to have the plug-in. With IE, it's probably not a bad idea to get used to this, since the next release will not have any support for java at all! I guess that's what happens when Microsoft tries to screw over a company that isn't completely dependant on them for survival.

This what I read once!
There is nothing wrong in your Applet.
I think you are using <APPLET ..> </APPLET>
tags to display the applet in your HTML page.
This tag is supported only upto Java V1.1 .
Since you are using Java v1.3 swing you need
to use Object tag for IE and <Embed>
tag for netscape.
Here is the HTML file for your applet and it runs fine.
YOu also need to download java plug-in to run this applet.
To convert the APPLET
tag to OBJECT and EMBED
tag you can download HTML Converter from java.sun.com.

You should use the latest plugin: 1.3.1_01a http://java.sun.com/getjava/installer.html
There is no need to embed you applet.
The plugin recognize the APPLET tag in IE and NS.
Life is easy again

Hi all,
I am having a similar problem. I have a SWING Applet & I have downloaded & installed the Java Plug In Version 1.3.1_01
I am using IE 5.0 & have tried using both JDK1.3 & JDK1.3.1.
When I try to view my applet, I get a class not found exception.
This also happens when I try to run the Swing Applet demos in the JDK Folder.
Any ideas???

I think this topic would get more replies in the Applets forum...
