V.Narayanan commented on DERBY-941:
-----------------------------------

Hi Rick,
Thank you for the reviews of this patch. The class EmbeddedConnectionPoolDataSource40 ,which
,has been added as part of 1137 is also present in this patch which as indicated by a class
level comment in this patch is a dummy implementation which was to be removed after the commit
of 1137. I am on this one. I will do this re-submit the patch again
thanx
Narayanan

>          Key: DERBY-941
>          URL: http://issues.apache.org/jira/browse/DERBY-941
>      Project: Derby
>         Type: New Feature

>   Components: JDBC
>     Versions: 10.0.2.0
>     Reporter: Rick Hillegas

> As described in the JDBC 4 spec, sections 11.2, 11.7,  and 3.1.
> These are the methods which let app servers listen for connection and statement closure
and invalidation events.
> Section 11.2 of the JDBC 4 spec explains connection events: Connection pool managers
which implement the ConnectionEventListener interface can register themselves to listen for
 "connectionClosed" and fatal "connectionErrorOccurred" events. App servers can use these
events to help them manage the recycling of connections back to the connection pool.
> Section 11.7 of the JDBC 4 spec explains statement events: Statement pools which implement
StatementEventListener can register themselves to listen for "statementClosed" and "statementErrorOccurred"
events. Again, this helps statement pools manage the recycling of statements back to the pool.
