They are guaranteed to act like they are executing through the same connection, even if they aren't (not sure how loose the spec is). You should check the JDBC specification to make sure, but I would imagine that splitting statements across connections would be more trouble than it's worth... I doubt very seriously that anyone would ever want to do this. > Or is connection pooling only for not actually closing the physical database > connection on myConnection.close(), instead returning it to the connection > pool? Pretty much. The connection pool simply ... pools connections. Once you have a connection, you can do whatever you want (including never returning it to the pool, which isn't a good idea, of course). > A different way of asking this is does connection pooling pool connections > within an application connection (myDataSource.getConnection() and > myConnection.close()), or between application connections? Well... when you call myDataSource.getConnection, it gives you a connection from the pool. When you call connection.close(), it returns the connection to the pool. Technically, while you have control of the connection, it's not pooled... it's "out of the pool with the intent to be returned soon". > If this question doesn't make sense, I can clarify. Thanks a lot. I hope my answer makes sense ;) - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGYH4s9CaO5/Lv0PARAihvAJwKgt3EccemfZ9AhtT6JI0EKAjF7wCgnu8g v0pYh6pxJPAZTt2lEGZXjJ4= =AGDl -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
