the alternative is installed. As for adding them for the Sun JRE/JDK,
the easiest way is to see what the openjdk rpm does and replace the
paths with where you install the Sun VM. To see what the openjdk rpms
do, you can run 'rpm -q --scripts java-1.6.0-openjdk{,-devel,-plugin}'
No, the Auto/Manual mode only decides which group is chosen. In Auto mode,

the group with highest priority is always selected. In manual, whatever is
selected stays that way even if a higher priority group is installed.
PS: Out of curiosity.. why do you need the Sun VM? Is something lacking
in OpenJDK?
I had wanted to use NetBeans for PHP and also try out its new Python plugin, and I believe they need the latest version of Java, because without it I get error after error. Since I'm not a Java programmer, I don't have time to determine how to get it to play nice with the OpenJDK.
PHP and Python plugins don't work with the NetBeans in the repository, or at least they didn't two months ago.
