You are certainly welcome to use a JDBC driver directly in your own
applications, in any manner that you wish.
The reason that JDBCRealm exists is to configure *Tomcat* (rather than your
application) on how to look up users and their associated passwords and roles,
so that you can use container-managed security for your web applications.
These concepts are defined in the Servlet Specification, version 2.2, which
you can download at:
http://java.sun.com/products/servlet/download.html
as well as being discussed in numerous books and magazine articles.
