What do you mean by keeping the connections among jsp pages? If you
open a connection, it is open. If you close it - it will be closed.

Do you store connections in session? Is your session serialized? In
general you cannot store connections in session, because session can
contain only serializable objects, connection is not serializable.

Post your test case and exception stack trace. Without this
information we will not be able to help you.
