Oracle GlassFish Server 3.0.1 Application Development Guide

Authentication With ConnectionFactory

If your web, EJB, or client module has res-auth set to Container, but you use the ConnectionFactory.createConnection("user","password") method to get a connection, the GlassFish Server searches the container for authentication information before using the supplied user and password. Version 7 of the GlassFish Server threw an exception in this situation.
