Now that Mac Mini is out, my ultimate home server is a reality. But I have never used Linux PPC before. Is there a viable JDK on Linux PPC? Which version? Is 1.5 available?

I need to run Tomcat 5.5 and PostgreSQL on it.

Thanks!

At present, the the IBM Java Development Kit is the only one that is marked stable for PPC.

It is in the portage tree, the ebuild is called ibm-jdk-bin

The only java 1.4 for ppc is the ibm one. Sun java for ppc dosen't exist, and the open blackdown java is only 1.3.x for ppc... :cry:

Sofar, the IBM jvm runs flawlessly on my Tibook. On x86, IBM's jdk is at least as fast as Blackdown's or the Sun's, but uses a little more memory (0% -> 10%, depending on the app). So in terms of performance, it's also probably OK (at least, i don't have any complaints).

Blackdown is not open, it's binary only. The Blackdown people have a NDA with Sun. The project started because at the time (JDK 1.0.1) Sun didn't want to invest in time/money/people for a Linux port. It IS a pity that they didn't update the LinuxPPC-port to v1.4.2.

:lol: Yeah, the year is 2005 and I am doing some of my professional java development in 1.5. Blackdown is still stable but has been stuck at 1.3.1 for years.

Nope, nothing changed. The Blackdown-jdk IS stable on PPC but only 1.3.x, while they have a 1.4.x compliant JVM for i386 and AMD64.
