Java Applet

Hi guyz.
I recently tried to upload Java Applet into my website.
But it doesn't display anything.
I works on my computer when I use appletviewer.
But it doesn't show anything on my website.
My web-host is geocities.

I tried googling for solutions,
and some websites mention that we have to convert it to JAR first
in ordrer to run on the website, due to web security reasons.
I tried it as well, and it doesn't work.

Can anyone help?
Thanks

yes. I tried that as well.
But that was only because I thought appletviewer
works only on HTML files?
But I could be wrong...
