Ive made a mostly portable openJDK distriution. If you want to try it, you must at the moment just use a 7zip self extracting archive. In the future i will try make it comply with the PAF.
If you have a .BAT file or similar for a compiler, you must manually enter the JDK path in the file. (javac.exe)
I have used this many times, and it appears to work perfectly!
Please give any and all feedback.
SORRY THE LINK IS DEAD. I AM RECOMPILING.
