Pro JSF and Ajax

Common J2EE architecture for a typical multitier software solution, serving a retail
company
In this scenario, the application developer is forced to provide not one application but
three. This architecture contains one application for the Web interface, one for the mobile
device, and finally one for the Telnet device (such as a VT terminal or handheld character-based
device). All three applications use their own technology stack, which for the administrator or
application developer will be a maintenance nightmare, and may cause issues with security
and scalability. For the application developer, it all boils down to one question: "How many
technologies do I have to learn in order to successfully build a complete solution for my
project?"
