Well, its funny because I'm running on an AMD 64 but I cannot install the ia64 while I can, and have in the past, installed i586. The problem then was that I couldn't install bluej. It was a .jar and I typed
java -jar bluej*.jar
...and there was some error.
when you say the the amd64 .bin file you mean is64 .bin, right?
Edit: Nevermind I got it all working. I installed the wrong one. Apparently they don't have a 1.4.2 for AMD 64's so I had to get JDK 1.5.0 for AMD 64
