Summary

In enterprise application development, servlets occupy a crucial role in the implementation of the presentation tier and also in forming the bridge between the presentation and the business layer. Although they form a small part of the entire J2EE framework, the Servlet 2.3 API along with the JSP specification provides the backbone for a full-fledged application framework for the presentation layer and for interactions with business components such as EJBs, JMS, and JDBC components, among others.
