i have an applet in the html page and browser cannot load class.
did anybody have this problem ?
it's weird but the .class does exist and is in
the same directory as the html file.

Have a look in the Java console and see why it's not loading.
It may be finding it ok, but it's throwing an unahndled exception.

I too had same problem.check your HTML code properly.May be you are missing something.
Inside Applet tag give your class file name in code parameter and comment the whole html code if you are writing in Source Code.
I hope it may solve your problem

I have a similar problem with one of my clients. We have an applet that works fine everywhere we test it EXCEPT at this particular client in which they get the same message you are reporting. We haven't confirmed it yet, but I think they need to upgrade their Microsoft Virtual Machine. Just a thought for you to look into...

Also there are often problem with things that work fine in IE not loading in Netscape and visa versa. Checking the console is step one.

Swing classes, including JApplet, won't work in most browsers. You'll need the plug-in from Sun:
I agree. Here's the link:
