Design issue for MDB and JDBCs

I've got a design issue.

Should I make JDBC calls on the MDBs or 'outsourced'
it to a Stateless Session Beans?

You see, the code has

public void ejbCreate() throws CreateException {
try {
InitialContext ic = new InitialContext();

dataSource = (DataSource)
ic.lookup(JNDI_DATASOURCE);

ic.close();

And the onMessage has got JDBC calls and closing the
connection once done, etc.

QUESTION: Is it going to be inefficient to have such
JDBC stuff for a MDBs that listens to hundreds of
messages from a given Queue?

What's your recommendation....to have them passed on
to a pool of stateless beans to handle to JDBCs?

Thank you.
