I'm J2EE guy. I like heavy stuff like EJB, MDB, ....
But it would be nice to get to know Spring 3.0 (there is a vision of a new project in 3.0 in next few months).
How should I start learning ? Is there any book, good tutorial itd (with examples ...)? (I've found only spring-framework-reference.pdf) but I dont know if its good way to start. Any hints ?
