If you start eclipse (or springsource tool suite) and get the following popup: you need to point eclipse to a JDK. You can't do this within the IDE itself so just close it. Then go to the directory where you have eclipse installed. Edit eclipse.ini in an editor that understands unix-style line endings (like notepad++ or wordpad). If you're running STS, the file will be called STS.ini instead of eclipse.ini. Look for the -vmargs line and insert a new line BEFORE it that specifies the location to your JDK's javaw executable. Like so:

Having spent the majority of my professional life on Windows with .NET, I'm not much of a Java troubleshooter. I speak the language and am familiar with a slew of frameworks, but I just don't know the JVM like I know the CLR. Yet.

If you are not going to have an internet connection, you'll want to pre-download the files you'll need. I suggest using 'yum downloadonly' to get them. I've spun up a brand new CentOS 5.5 VM and logged in. Oh man, does anyone else just love logging into a fresh install? Is my nerd showing? Sorry! The first thing I need to do is take on great responsibility, so for that I'm going to need great power: let's add my account to the su
