The Java Portlet Specification allows coordination on the UI layer with different means, such as events, application sessions, and public render parameters, in order to provide a deep and seamless integration between the different services. Portlet Concepts a portal is a web based application that commonly provides personalization, authentication, content aggregation from different sources and hosts the presentation layer of information systems a portlet is an application that provides a specific piece of content (information or service) to be included as part of a portal page web clients interact with portlets via a request/response paradigm implemented by the portal a portlet container runs portlets and provides them with the required runtime environment manages the life cycle of portlets provides persistent storage for portlet preferences a portlet mode indicates the function a portlet is performing in the render method standard portlet modes are: view, edit and help view: generate markup reflecting the current state of the portlet edit: customize the behavior of the portlet help: provide help information about the portlet a portlet window is the visual component used to display the content generated by a portlet within portal pages a window state is an indicator of the amount of portal page space that will be assigned to the content generated by a portlet via the render method possible window states are: normal, maximized and minimized Portlet Life Cycle The life cycle of a portlet is expressed through the init, processAction, render and destroy methods of the Portlet interface.
