Since we are working on a Linux-PPC32 system, the fastest way to get a Java Runtime Environment runnning is to get the JRE/JDK package from IBM (free registration required). You have to download the J2SE/JDK version 5.0 for 32 bit iSeries/pSeries from here.

Get the TGZ, uncompress it in /opt (or wherever you prefer, for the next steps we assume it is installed in /opt).

Now, all you need to get a running Java environment is export a number of environment variables as follows

export PATH=/opt/ibm-java2-ppc-50/bin:/opt/ibm-java2-ppc-50/jre/bin:$PATH
export JAVA_HOME=/opt/ibm-java2-ppc-50
export JITC_PROCESSOR_TYPE=6
#this will instruct jit to compile code for PPC604 aka G4
export CLASSPATH=.:$JAVA_HOME
export JDKROOT=$JAVA_HOME

It may be useful to add those exports to your .gnomerc in order to have an always working environment.

Now you can download either the installer version or the single JAR version of JMT and run in with

java -jar JMT-installer-0.5.4.jar

or

java -jar JMT-singlejar-0.5.4.jar

There you are! You have just completed the installation of JMT under Linux-PPC32
