  2. Web Container & Web Applications • Web applications are server side applications • The most essential requirement for server side application development are: • A programming model and an API • Server Side runtime support • Deployment Support

  3. Web Container & Web Applications • To meet these requirements when building and running web applications, the j2ee specification provides the following • Java servlets and Java Server Pages • In J2EE java servlets and java server pages are called web components • Web Applications • It could be a collection of java servlets, jsp pages, helper classes, class libraries, static resources, documents and images • Web container • A web container is essentially a java runtime that provides an implementation of java servlet API and facilities for JSP pages

  4. A packaging structure and deployment descriptor • The J2EE specification defines a packaging structure for web applications. The specification also defines a deployment descriptor for each web application • The deployment descriptor is an XML file that allows the customization of web applications at deployment time

  5. Java Servlets • Java servlets are small, platform independent server side programs that programmatically extend the functionality of the web server • The java servlet API provides a simple framework for building application on such web servers
