How are security requirements expressed in Java EE applications?
Security requirements in Java EE applications can be expressed using deployment descriptors.
What is the role of annotations in Java EE security?

How are components in Java EE applications secured?
Components in Java EE applications are secured by the containers providing two kinds of security: declarative and programmatic security.
Explain the difference between declarative and programmatic security in Java EE.
Declarative security in Java EE expresses an application component's security requirements using deployment descriptors, while programmatic security involves specifying security requirements in the code.
What is the purpose of annotations in Java EE applications?
Annotations save you from having to write declarative information inside XML descriptors.
