I have tried moving to netbeans b4, I just am way to used to blueJ. I iwll look into eclipse though.
Netbeans and Eclipse are similar in functionality and complexity. You might need time to get used to these "big" IDEs, but if you take the time, it might be worth it in the long run. I would advice to try the user tutorials for both IDEs. Netbeans have a good list of them here: http://www.netbeans.org/kb/trails/java-se.html
. Eclipse at least has an online help center with some getting started articles: http://help.eclipse.org/ganymede/index.jsp
