I think keyword here is "reload it again".

Why do you store connections in http sessions? Do you expect that on
serialization it will close the connection, and after de-serializing
it will restore connection to the database from the point when it
disconnected?

In general, it is a very bad idea to store connection in the session.
In particular, you cannot serialize session, since java.sql.Connection
is not serializable.
