The EJB timer service is a container-managed service that provides a way to allow methods to be invoked at specific times or time intervals. This course covers how to implement both programmatic and automatic timers in Java EE applications. It also covers how to implement batch processing, which is the execution of a series of jobs and is suitable for non-interactive, bulk-oriented, and long-running tasks. The second part of the course will cover security considerations for Java EE applications. The course will describe the Java EE security model. It will describe how authentication and authorization are applied in Java EE applications and will also describe the features of data integrity and how they can be applied in enterprise applications. You'll also learn about container-managed security and the use of roles and security groups. Finally, the course will demonstrate how to secure an enterprise application.
