This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Perhaps that would have been good information to include from the start? I don;t know if anyone who posts here is using DWR, but if there are, making people guess what your problem is isn't likely to get you much help.
Post the code you are having problems with, with explicit details about the problem. If there are DWR users here, perhaps then they may be able to help you.
