Hello! I just started learning Java at my university. We are using the book "Objects First with Java" by David J. Barnes and Micahel Kölling. 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: http://img176.imageshack.us/img176/5417/screenshoths0.png Java and Javac version match: http://pastebin.com/m2063432d Any ideas on what is wrong here? If you need me to supply more info, please tell me. Thank you in advance!
