AndroMDA is one of the most powerful Open Source MDA Generators on the planet. It is used all over the world for everything from simple CRUD applications to complex enterprise applications. AndroMDA comes with an array of ready-made cartridges for common architectures like Spring, EJB, .NET, Hibernate, Struts and even more. The project wizard gets you started in no time. An Eclipse integration is in the works and will be finished soon. If you have a custom architecture, AndroMDA can also help you - by writing a so-called cartridge, you can customize AndroMDA to fit your needs.
