To enable interoperability between Portlets and Portals, this specification will define a set of APIs for Portal computing addressing the areas of aggregation. The Java platform provides an standard referred to as JSR that standarizes how portlets interact with portlet containers and ensures compatibility across. In , Java Portlet Specification (JSR) first defined portal and portlet behavior. In , Java Portlet Specification (JSR) refined and built on.

Each Portlet produces a fragment of markup that it s combined with the markup of other Portlets, all within the Portal page markup. Exact details will be agreed early in the life of the JSR and communicated to expert group members.
The Java Portlet Specification defines a contract between the portlet container and portlets and provides a convenient programming model for Jse portlet developers. A portlet container receives requests from the portal to execute requests on the portlets hosted by it.

Usually, many Portlets are invoked to in the single request of a Portal page.
Client agnostic Support for multiple types of clients multi-device Simple Portlet API Support for Localization and Internationalization Hot deployment and re-deployment of Portal applications Declarative security same as to the mechanism found in Servlet and EJB specs Architected to support remote execution of Portlets The Portlet specification will be based on the Servlet specification.
