With NetBeans 6.1 final now available, I moved up from 6.0.1. Having been used to JDeveloper 's idiosyncrasies, this was a pleasant and smooth upgrade. Steps to upgrade: Download NetBeans 6.1 final . I used the Web & Java EE version. Install. I choose to have both GlassFish and Tomcat installed. Run the new version. It detected my 6.0.1 configuration and migrated it to 6.1. Reinstall some 3rdparty plugins like Mevenide . That's it!
