New to MDA. Need help in deciding UML and code-generation tool

Experts,

I am new to MDA and need your help in finalizing tools from UML diagrams to code-generation (at least stub/skeletons) . I searched on the net, but it seems there are too many and was not sure their differences. Here is what I am looking for.

1) UML tool which doesn't help me (eventually) create skeleton code, is useless.
2) Ideally I need free , open source tools .
3) It should work with Eclipse and also other open source application frameworks like Spring, Hibernate.
4) I would prefer tool which is best suited for web-services using Axis.
5) Should be acceptable in reverse engineering.

I am aware of these tools/frameworks , but I am not sure whether those work together efficiently or is there anything redundant in it ?
1) AndroMDA.
2) Eclipse EMF
3) MagicDraw ( paid ).
4) XDoclet

Please send me any helpful links. Thanks in advance !
