This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
What are the model driven development tools available out there? I am looking at some commercial tools like OptimalJ and Plex - I doubt that there are any open source tools that are as good as these are. Are there any more? Any recommendations on which tool is the winner? Thanks!
