This two-part article series demonstrates how to use declarative Java 2 Platform, Enterprise Edition (J2EE) security and Apache Geronimo's built-in Derby database to authenticate registered users and allow them access to a Web site using the Geronimo application server. Security is controlled using an SQL-type deployment plan that specifies which users or groups are allowed access to the Web site. Users are specified in a users table in Geronimo's built-in Derby database, and groups are specified in a groups table in the same database. This article focuses on setting up J2EE security and authenticating users through Geronimo's built-in Derby database.
