This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
other than that, JRUN (development version - free with 3 concurrent connections) also has support for EJB's and JMS / JTA. But the flip side is that it would cost you if you went into a production system with JRUN.
