I tried to download and install NetBeans IDE 6.1 on my machine with Ubuntu 8.04 installed, but the installer always complain about no Java Interpreter found.
Finally, I install NetBeans IDE 6.0.1 from Ubuntu "Add/Remove Applications" first, then download and install Java SE Development Kit 6u10 with NetBeans IDE 6.1 Bundle, which can be downloaded here. I have two NetBeans now.
