Tutorial: Controlling Access with Servlet Filters

This tutorial describes how the Financial Brokerage Service (FBS) sample application uses servlet filters to control end-user access to application features. Introduced in the Java Servlet 2.3 specification, servlet filters enable developers to modify the behavior of servlet-based applications without touching existing code.

This tutorial assumes that you are familiar with the FBS and have installed and configured the required software as described in About the Financial Brokerage Service.
