I think you can do a

echo 'MYGLOBALVAR="somevalue"' >> /etc/bashrc

in the % section to export your variable for bash users.

Perhaps a

sed -i.orig -e '/MYGLOBALVAR/d' /etc/bashrc

in the %preun section could solve the problem.

You can include the JDK package into Requires:

BuildRequire: java-jdk

Depending your box, this name can be changed.

Well, I've never tested this situation. You can test and send us the result ;)

I really don't know if I made mistakes or if there is other way to do
that. Please, send us other suggestions.

Thanks.
