Installing both of JDK 1.4.x and 1.5.x

[Matt Galvin]

Yes you can use both, I do for a similar reason, here is what I do.

NOTE: I do this all in /opt

Download the 1.4 and 1.5 .bin files from sun.

sh ...1.4.bin
sh ...1.5.bin

export JAVA_HOME=/opt/jdk1.5.0; # (or whatever you call your dir)
export PATH=$JAVA_HOME/bin:$PATH

... do stuff with Java 5 (1.5) ...

export JAVA_HOME=/opt/j2sdk1.4.2; # (or whatever you call your dir)
export PATH=$JAVA_HOME/bin:$PATH

.. do stuff with Java 2 (1.4)

If you want to use both at the same time open 2 shells, in one shell
export the Java 1.5 stuff in the other shell export the Java 1.4 stuff
and use them both at the same time :)

Hope this helps,

Matt
