Java EE is an industrial standard programming platform that makes cross-cutting concerns like security and transaction into standard services to free developers from muddy infrastructure coding jobs. The security services in Java EE enable developers to build strong and elaborate protections for their applications with minimum effort. Apart from Java EE, Spring is a fantastic and popular open source framework designed on top of the Java EE standard that addresses the missing or problematic pieces from earlier versions of the Java EE specification (1.0-1.4). Spring's features and value plus the fact that a Spring container can live in a Web server without a heavy-weight application container contribute to its continued dominance in the application framework market. Acegi designed for Spring provides flexible, powerful, and comprehensive security beyond what's available in the Java EE standard. The two independent security systems are discussed and compared from different angles in this article to help developers build strong, efficient, and elegant security solutions for their applications.
