Blackberry provides a “Java plugin for Eclipse” that can be downloaded and used for eclipse-based blackberry development. But beware, what you download is not an eclipse plugin. Instead, it is a full eclipse download with the plugins pre-installed. I didn’t want a new copy of eclipse just for Blackberry development. I wanted to use my already well configured Helios installation to be used for Blackberry development as well. So, i chose to use the provided update site – http://www.blackberry.com/go/eclipseUpdate/3.6/java – to install the plugin to my existing Helios installation.

The issue is that, I was unable to install the plugin using the aforementioned update site and noticed that others faced the same problem too. After a lot of failed attempts, I finally discovered a different way to solve the problem. I downloaded the full “Java Plugin for Eclipse” from the Blackberry download site and just copied all the net.rim.* files from the plugins and features directory to my Helios installation.

Worked for me and I am a happy camper!
