Also if its serious you can contact me
The person who is able to answer your question will probably prefer to respond to you here. That is the main idea of a forum. I don't know much about java applets myself, apart from CR's one which I can configure blindfolded, but I would do four things initially:
1. Read the instructions three times.
2. Make sure all of the files are uploaded
3. Double and triple check all HTML and any scripting to make sure it will fully support what you want to do.
4. Make sure that your webhost actually allows java applets. I can't see why they wouldn't but most free webhosts place severe restrictions on what they will allow and support including filetypes and indeed the size of the files.
