I have a spec here which talks about sending a string query to another system. The string is entered in a html form and then a servlet opens a socket connection to the consumer system written in C++. The system then processes the info and sends a response. When the system will finish the processing and send the data back is an unknown. I am caught between developing a pure sockets system versus using JMS. But the catch, I guess is that the other sys being in C++, cannot talk that easily to the JMS system. But again the user can't be kept waiting for the response a)What is a good arch for doing this? b) Any good literature (online preferably) on developing web based asynchronous socket apps?    More>>
