Editing Portlet (section)

=== Portlet containers ===
A portlet is managed by a portlet container.<ref name=":1" /> A portlet container runs portlets, provides them with the required runtime environment, manages their life cycles.<ref name=":0" /> A container also provides persistent storage mechanisms for the portlet preferences.

A portlet container receives requests from the portal to execute requests on the portlets hosted by it. A portlet container sends data to the portal for aggregation, but is not responsible for aggregating the content produced by the portlets; the portal itself handles aggregation.<ref name=":0" /> A portal and a portlet container can be built together as a single component of an application suite or as two separate components of a portal application.
