[rules-dev] Feedback on Drools - Spring / what can I do to help?

[Paul Browne]

All you need to know about Spring: You write your code as JavaBeans, and 
Spring does the rest.

Yep, I have some code to do steps 1-3 that I talk about below, so a 
branch in SVN would help me add it to the project.

Did Xavier? mention if he planned to more work on this ?
