I need JNDI and JDBC connection pooling so that I can test the ManagedConnectionFactory path. Basically, retrieve the DataSource from JNDI and make sure that the JDBCCacheLoaderTest works fine with it.

I'm gonna try setting this up in the test using libraries from AS. Otherwise, I might failover on standalone pooling from C3P0 that I could bind to JNDI and try that.

C3P0 stuff is moving forward. I hope to have it ready by Monday including documentation, fingers crossed :)

What resources do you need from the AS?  Can these be emulated?

+1!!  :-)

1.4.1.
