Step 3: Implement the Abstract LoginModule Methods

The LoginModule interface specifies five abstract methods that require implementations:

• initialize
• login
• commit
• abort
• logout

See the following sections and the LoginModule API for more information on each of these methods.

In addition to these methods, a LoginModule implementation must provide a public constructor with no arguments. This allows for its proper instantiation by a LoginContext. Note that if no such constructor is provided in your LoginModule implementation, a default no-argument constructor is automatically inherited from the Object class.
