Can someone tell me the difference of ManagedConnectionPool?

[liujw2001]

Hello
I am a jackaroo who is reading the the code of JCA.

I find two ManagedConnectionPool in Jboss code, one is JBossmanagedConnectionPool ,the other is InternalmanagedConnectionPool. Both of them are in package org.jboss.resource.connectionmanager

Can some one tell me the difference between them?
Thank you!

In psuedo code:

JBossManagedConnectionPool implements Map<ConnectionRequestInfo/Subject, InternalManagedConnectionPool>

Thank you very much.

All in all, The "JBossManagedConnectionPool" is used to manage "InternalManagedConnectionPool".
