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.
That is too broad of a question. Can you elaborate more?(like what kind of environment and if you are using or planning to use specific J2EE platforms etc). If you come forth with more info, this forum can really help you. Kishore.
