This package provides classes and interfaces needed to interact with the application in order to execute the authentication and authorization processes. It is a classical callback mechanism: one retrieves information (i.e. for authentication purposes) and one display some messages (for example error messages).
Note that the current implementation of this package is not complete, that is, not compatible with desktop implementations of the Java programming language. It contains only what was needed to make the compiler happy, that is, classes required by other packages.
