Hello, I'm planning to implement a quite big web based commercial application. It's complexity can be compared to this of ebay. In theory if it will be successful there could be a lot of users of it. Unfortunatelly me neither my team we don't have money for a commercial application server.

Users will keep money in this "system", I was then wondering how stable and secure is JBoss. Are there any big commercial applications based on JBoss ? Or maybe I shoudl someone who would give money for a commercial J2EE implementation ?

I would be grateful for all opinions
