What is AndroMDA? (taken from http://www.andromda.org/pages/whatisit.html)
In short, AndroMDA is a code generator framework - it takes a Unified Modeling Language (UML) model from a CASE-tool in XMI format and generates custom components. It comes with a set of sample templates that generate classes attributed with XDoclet tags. One build step later, the XDoclet tool generates full-blown components that can readily be deployed in the JBoss application server (and the other servers that XDoclet can feed).
