Develop portlets for cooperation
This topic lists the steps required to develop portlet applications that publish properties to the property broker for interactive communication. You should be familiar with basic portlet programming concepts before working with the APIs provided by the property broker. The property broker programming model builds on the portlet programming model.
Portlets communicate through properties. These properties must be registered and given values. In this section the act of assigning a value to a property will be referred to as generating a property value. There are two approaches to developing a cooperative portlet. The first involves editing or creating a WSDL file which contains properties and their values. This is referred to as the declarative approach. Alternately, IBM portlets can be developed programmatically using Java methods. This will be referred to as the programmatic approach and is not available for standard portlets..
