Hi group,
I need to run 32 bit java on my 64 bit PC. I don't want to make the 32 bit java my default. Can I do it??

Yes. Install the 32-bit java somewhere and create a script that will set the JAVA_HOME variable and set the PATH to something like:

PATH=$JAVA_HOME/bin:$PATH

Run this script whenever you want to run the 32 bit java.

I do this all the time to swap between 32/64 and 1.3/1.4/1.5 and 1.6 JVMs.
