Security is an important consideration that should be at the forefront of our minds when we design our user interfaces. Fortunately, many components in the Tomahawk component library have built-in security features that help to integrate our user interfaces with the Java security architecture.
For example, we may want to display certain controls on our screen only for certain users when they login to our application. An administrative user may be able to modify other users' accounts while a normal user cannot. How do we ensure that the UI components associated with higher privileged users and use cases are not exposed to users with insufficient privileges?
Before we discuss how to implement user interface security using Tomahawk components, let's examine the underlying security mechanisms of the Java EE runtime environment.
JSF applications run inside what is known as a web container. A web container is a standardized Java EE runtime environment for web applications...
