Then get a little less so before you start programming.

I don’t know. I think Glassfish probably has its own support forum; you
might ask there.

However, I would recommend not starting Rails development with JRuby,
and not starting Rails development on Windows. Both of these will
make setup difficult. If you don’t have access to a Mac or other *nix
box, then you can download Virtual Rails (caveat: I’ve never used it,
but I’ve heard great things about it), which will save you the setup and
give you a ready-made Linux VM for Rails development.

Best,
