Installing just Java VM after a basic install

How does one install the Java VM with 6.2.0 PE, if you
don’t want all the development stuff that PE has?

I tried pointing the installer to the files
in /fs/cd0/repository/j9ive-1.5-qnx.qpk
in /fs/cd0/repository/j9ive-1.5-qnx.qpm
etc, but the installer says it can’t open the repository.
I’m offered the option to install the various CPU versions
of PE but that includes stuff like the compilers, IDE etc
that I don’t want for this install.
