1. Create a webs account here: Webs - Make a free website, get free hosting
2. Select the "HTML_ONLY" option.
3. Create an html file that includes the <applet> tag for your webclient and anything else you want on that page (source code can be found in a lot of places).
4. Upload the file you just created and make sure it is called webclient.html
5. Done. Go to yourwebsite.webs.com/webclient.html to see the result.
That's basically all there is to it.
Use the search bar to find the webclient html source code, etc.
Good luck.
