This week's book giveaway is in the Testing forum. We're giving away four copies of Data Structures the Fun Way: An Amusing Adventure with Coffee-Filled Examples and have Jeremy Kubica on-line! See this thread for details.
I have a swing based client. All data displayed in the client side are pushed via JMS from server side (PSUH mode). My question is that I want to prevent different users to invoke the same business method at the same time. If this happens, the client should display a warning message. Can anyone provide a better solution to solve this design issue? Highly appreciate you in advance.
