This chapter will introduce portlets through the Portlet 2.0 Specification. The Portlet 2.0 Specification defines how portlets work within a portlet container, and what functionality they can provide.

This chapter will focus on portlets that utilize JSP as the view layer, though there is no restriction on which technology creates the view for a portlet. In Chapter 10, Frameworks in a Portal, we discuss JSF portlets.
