Portlets and Web Service for Remote Portlets

Portlets and Web Service for Remote Portlets (WSRP) are available with Portal Server. Portlets are web components specifically designed to be aggregated in the context of a composite page. Java Specification Request (JSR) 168 specifies how portlets interact, how their life cycles are managed, and provides details of their semantics.

WSRP provides a presentation-oriented web service. A presentation-oriented web service returns the headers formatted through markup and ready for display in a web browser.
