I do it in another different way: First - I have a JavaBean that sets my connection pools Second - My main servlet' init method uses this Java Bean instance to get an data source pool object Third - create my sql... I guess it's right.

I do it in a different way : I have a servlet in charge to set all pools, and I have a class with statics methods to manage the pools, creating, test, and show their use. This class is shared with all contexts through a jar in common/lib. So I have a servlet, with all configuration of the pools in param in the web.xml. this servlet can create pools (in its init method), test and show it, and show statistics. I works great, and I can share a pool among contexts. I use the bitmechanic connection pool, a little old, but still works. http://www.bitmechanic.com/projects/jdbcpool/dist/jdbcpool-1.0b1.zip I put the jar of the pool in the common/lib dir. I f anyone is interested in the ConnectionManager, I can share it, it's an eclipse project with ant build file that generates both war and the lib jar.
