AndroMDA is a great and highly customizable tool if you want to generate a maximum of your Java or C# sources! (And if you can export you modeling as XMI files.) It is ready to generate code for the most important target technologies, especially for web based applications: JSF, Struts, Spring, Hibernate and such (yes I just know the Java part).
The central tool for support is their user forum, where technical help is always gently and quickly provided.
The project teams strength is their competence in technical issues. They put much less effort to keep the material on their projects website actual: many resources there are unfortunately outdated. So better stick to their forum when you try to manage the steep learning curve of getting familiar with AndroMDA!
