This is a big jump step for Netbean 6 preview (M9) which is including Ruby and Ruby on Rails plugin in it. I use Netbean since 3.2 version to develop any desktop java application. Now with Netbean 6, I also can develop Ruby on Rails application easily. Here are some Ruby/RoR features that you can use with Netbean 6 :

* Tools > Ruby Gems
this tool will provide you gems package management easily. Netbean 6 will include automatically ActiveRecord-JDBC gems module.

* There are two sample interesting Ruby on Rails applications, i.e. Flickr on Rails Sample App and Ruby Weblog Sample App. With this sample, we can learn many things about Ruby on Rails tips and trick.

* You can create Ruby / Ruby on Rails projects easily

* JRuby is a default ruby intepreter in Netbean 6.

I will continue this conversation with how to develop a simple RoR application with Netbean 6.
