I have to develop an application for pharmaceutic industry and I was thinking to use J2EE for that but 2 days ago I "discovered" Ruby on Rails and right now I'm evaluating to switch and to use RoR but I'm afraid if this technology is mature enough for enterprise applications not just for web sites.

So I would like to know which kind of application you are developing with RoR and what you think about it.

Thank you so much
