The usual practice would be to have your MIDlet talk to a middle tier,
likely Java Servlet based, which in turn either uses JDBC to talk to your
database or else uses EJBs encapsulating your business logic and which
in turn talk to you database.

Sun encapsulates this best practice via our Wireless Blueprints, a part
of the Java Blueprints online at http://java.sun.com/blueprints.


You can learn more details and access sample code from the Wireless
Blueprints via my webcast "End-to-End Using the J2ME and J2EE Platforms", at:
