I got to this page:
It lists, for the J2SE SDK:
Linux RPM in self-extracting file (jdk-1_5_0-linux-i586-rpm.bin, 42.50 MB) Download Now!

Linux AMD64 self-extracting file (jdk-1_5_0-linux-amd64.bin, 40.11 MB)
Well, I use Linux on a PPC machine. Debian has ports for the
following architectures: m68k, sparc, alpha, arm, mips (and little
endian mips), hppa, ia64 and as Dave mentions, s390. Oops, almost
forgot - the 'sh' architecture too. J2ME most likely runs on some of
the embedded ones, but that's a fairly limited platform compared to
And that's just Linux. One might also consider using other systems
such as one of the BSD's, or something else even less widely used.
In reality, Java (*) does work on my computer, but not the Java (TM)
Technology from Sun.
I use GNU gcj to compile the code (the "blackdown" folks also had
something, but I'm not sure it's current). I don't suspect it would
be difficult in the slightest to make Sun's Java run on all the
platforms Linux runs on, however I don't know if it's legal to do that
porting yourself. Or if it is, you most likely can't share the
results with your friends. In any case, what is available on that
site does not run on my machine.

(*) Or whatever the heck we're allowed to call it - to download Java,
err, I mean the Java SDK, you must agree to the following terms:
including always using Sun trademarks as adjectives. For example
( http://www.sun.com/policies/trademarks/examples/ex1.html ):
"My business relies on Java"
"My business relies on the Javaplatform"
RMS seems a bit insistent about "GNU/Linux" at times, but... this is a
bit over the top!
