Hi there,
Can I cache a Connection object on client side. Will this affect the performance of database. Say the database allows 25 connections and if I cache one only 19 connections are left.

Caching of database Connections is normally handled via a central Conection Pooling mechanism. The pool opens all the required connections and you request connections from the pool and not directly from the database.
I hope I understood your question correctly. This assumes that the application is acting as a client to a database server, and the application itself may be a server to the next tier.

Yeah, look into connection pooling which should be handled seamlessly by the container (for example, Resin). If you have any specific questions, you can post them here!
I agree. Here's the link:
