Casper,
To get started with Java on Fedora 8, I installed
java-1.7.0-icedtea-devel - 1.7.0.0-0.19.b21.snapshot.FC8.i586
as well as BlueJ using the .jar file from it's website.
Used this command to start the BlueJ installation:
/usr/lib/jvm/java-1.7.0-icedtea-1.7.0.0/jre/bin/java -jar
bluej-221.jar.
This worked fine and the installation linked to
/usr/lib/jvm/java-1.7.0-icedtea-1.7.0.0 as the JDK directory.
Loaded up BlueJ, imported the first project from the CD that came with
the book. Creating new objects were no problem
at all. However, as soon as I tried to invoke a method, I got this
error: http://pastebin.com/m2efbebbd
Here's a screenshot of BlueJ and the error as well:

Java and Javac version match: http://pastebin.com/m2063432d
