Implement the action processing to make the data available to the property broker if it is a cooperative source or, if it is a cooperative target, to get data passed in by the property broker.

Now you'll use the Cooperative Source Trigger to add a user interface (UI) to your JSP file, create the action, and make the data available to the property broker.

At runtime, the WebSphere Portal property broker USES type and namespace attributes to match source data to actions on the cooperative portlet.
