Getting Started with Web Applications

A web application is a dynamic extension of a web or application server. Web applications are of the following types:

• Presentation-oriented: A presentation-oriented web application generates interactive web pages containing various types of markup language (HTML, XHTML, XML, and so on) and dynamic content in response to requests. Development of presentation-oriented web applications is covered in Chapter 4, JavaServer Faces Technology through Chapter 9, Developing with JavaServer Faces Technology.

• Service-oriented: A service-oriented web application implements the endpoint of a web service. Presentation-oriented applications are often clients of service-oriented web applications. Development of service-oriented web applications is covered in Chapter 19, Building Web Services with JAX-WS and Chapter 20, Building RESTful Web Services with JAX-RS in Part III, Web Services.
