1.6. A complete Seam application: the Hotel Booking example

The booking application is a complete hotel room reservation system incorporating the following features:

The booking application uses JSF, EJB 3.0 and Seam, together with Facelets for the view. There is also a port of this application to JSF, Facelets, Seam, JavaBeans and Hibernate3.

One of the things you will notice about this application is that it is extremely robust. You can open multiple windows, use the back and browser refresh buttons, and enter nonsensical data, but the application is difficult to crash. Seam was designed to make building robust web applications straightforward, so robustness that would previously be hand-coded comes naturally and automatically with Seam.

As you browse the source code of the example application and learn how the application works, pay particular attention to the way the declarative state management and integrated validation has been used to achieve this robustness.
