While I was looking for how to install portable java without administrator privileges (without editing the registry) and all self contained on the flash stick, I ran across this discussion:
http://blenderartists.org/forum/archive/index.php/t-110943.html
It's in the context of running java apps from browsers at school that aren't supposed to run java. I came here again searching for java and found some mention of a halted project for portable java that's waiting for a new build. Apparently these kids have some nearly-portable form of java running that they can hand each other in a quick install package, but I really am loathe to download .exe's from young hackers. Is there any way their methods are useful for the portablapps community (in making Java runtime functional from within FireFox Portable, all on usb, no admin priv?)
because first apparently they are using Thinstall which is very expensive or illegal and second their file has been deleted from the server.
But thanks for your comment anyhow cause it certainly is a problem worth working on and welcome to PortableApps.com

If you read the discussion on that site, you will note that what they are doing is dependent on a $5,000US application called ThinInstall from VMWare. They are using demo versions of that product, which then, of course, will fail when you most need it! At best, it is of questionable legality and certainly immoral to distribute apps this way. I'm afraid this website will not be contributing to the problem.
