Cooperative portlets

---

The term cooperative portlets refers to the capability of portlets on a page to interact with each other by sharing information. One or more cooperative portlets on a portal page can automatically react to changes from a source portlet triggered by an action or event in the source portlet. Portlets that are targets of the 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 users' overall 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 the programmer's awareness of the existence of the other cooperative portlets.

The following topics describe portlet cooperation in WebSphere Portal.
