#### Application Developer

The application developer is responsible for the following:

- Specifying roles and role-based access restrictions for application components.

- Defining an application’s authentication method and specifying the parts of the application that are secured.

An application developer can use tools such as `deploytool` to edit application deployment descriptors. These security tasks are discussed in more detail in the Security chapter of The J2EE 1.4 Tutorial, which can be viewed at `http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html`.
