This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
I am looking for a free JMS implamentation. The system doesn't ahve to be very good. The only real constraint is that we can have 200-300 people "trade stocks" at once. Basically, we'll have people submit buy/sell offers, and those offers will then apprear on the "tickers" (we're actually using order books) of the other users. I should imagine this isn't too high a load. The hardware will be a decent (meaning average) server. 1) Is the reference implamentation from Sun good enough? 2) What about JBoss? 3) What *free* JMS implamentation do you recommend and why? 4) Can I use one EJB implamentation and a different JMS implamentation? --Mark
