I am developing a classified J2EE system for a Federal government agency here in Washington, DC. I have years of experience with Hibernate and am using it on this system. The problem is: this system shall get some data from Microsoft Access database too. Hibernate supports HXTT Access JDBC driver; however, because it is developed and sold by a non-U.S. company we cannot use it on our classified system. Only US-based software and hardware products can be used on classified network.

What are other suitable production-quality JDBC drivers (commercial or free) that I can use with Hibernate? Any other idea? Thanks.
