Business Components for Java - Pooling

Question

I need a little bit of clarification regarding business components for java...
I would like to create a jdbc connection pool for my application to avoid the overhead of creating new jdbc connections each time a client connects.
Since I'm using BC4J, and the jdbc connect is contained within the bc4j components, I connect to the database using:
session.getTransaction().connect("jdbc:oracle:thin:test/test@ccmain:1521:clincare");
Does the BC4J architecture do any connection pooling itself? My plan was to create a pool of ApplicationModules that could be easily and quickly accessed, but if bc4j already pools the jdbc connections internally, then I'm not sure I would gain any performance with my ApplicationModule pool.
Any input would be appreciated! Thanks!

Strictly speaking, in JDev/BC4J 3.1, the answer is no. BC4J 3.1 offer Application Module pooling and since AM's are paired one to one with connections, using a pool of AM's is pretty much the same as using a pool of connections.
However, in JDev 3.2 we've dramatically improved the features for use in a high-throughput Web application scenario and in doing so have implemented a more flexible application module pooling mechanism as well as a connection pooling mechanism that work together to allow developers to exploit application module instances to retain pending state without "pinning" that pending state to a particular AM instance and without "pinning" a dedicated database connection.
Early customer previews we've done on our 3.2 features have been receving rave reviews, so we'll excited to get it out to a wider audience this Fall.
For now, you're best bet is to exploit the application module pooling mechanism.<HR></BLOCKQUOTE>
Is JDev 3.2 going to include a support for registering application module not from the property file, but using specific database username and password for the underlying connection ?
