Help! Microsoft Publisher/Java Question

I currently have a website that I developed with MS Publisher 2003.  There is a website that has a java based game that offers it for download and use on the web and I would like to add the downloaded game to my site (they provide a bunch of files (sample.html, java files and .class files).   I am a novice (i.e., am clueless) and do not understant the files and what is needed.

I would like to add the game (and appropriate copywrite information as requested by the game site) but would like to keep the same look as my MS Publisher produced pages.  I have not been able to figure out how to import the java-based game into Publisher to publish it to the web and I do not know the way to add/copy the game related files directly to my hosting site (and if I did, I'm not sure how to keep the same formate/tempate without using Publisher (which seem to generate incredibly complex code when creating the files to be published to the web).

Any guidance/help would be greatly appreciated.
