Java Open JDK 7 / SDK 1.7 for Apple PPC iMac / Macbook G3, G4 and G5 – Part 1

Part Two Is Here

Intro

Needed to run latest google app engine development tools on my aging Apple iMac with PPC processor and Mac OSX 10.5.8 – the latest/last incarnation for PPC systems.This was to overcome a bad version in .class file message in the google implemention.

This limited my non-intel Power P/C chipset system to JDK 1.6 as a max working java SDK, and even then it was problematic. So needed to see if it was possible to install the newer JDK 1.7. Since java is so tightly woven into the fabric of OSX, after a lot of research, it became obvious there was no way to do this the ‘apple way’. So i decided to try the open java 7 build as a virgin installation, thus avoiding any reference to the apple versions of java.

Turned out, this is a long-winded topic needing more than a single post. So will describe this ordeal in more than one post. In this post, i’ve listed the reference links used to research this topic. Turns out this is not as super complex as i first thought but for the mo. please review these links :

New Soft Link Layout – Post Install

This is not the correct place to show you this set of logical soft links, but just stuck it here for the moment. It shows my new /usr/java7 folder holding just the fresh links to the newly installed java7 bits.
