Cooperative portlets are available in IBM® WebSphere® Portal version 6 and later. Cooperative portlets can interact with each other to share information.
One or more target portlets on a portal page can automatically react to changes from a source portlet when the source portlet triggers an action or an event.
Portlets that are targets of this event can react so that users are not required to make repetitive changes or actions in other portlets on the page. This provides a coordinated and consistent behavior between the portlets on the page and enhances user experience.
Cooperation between source and target portlets is facilitated by a WebSphere Portal runtime entity called the Property Broker. Portlets on a page can cooperate in this way even if they were developed independently, without awareness of other cooperative portlets.
