The context is a set of property value which is provided by a portlet and can be either delivered to multiple portlets in the target page(which may be a dynamically launched page or a static page) or a special portlet in the current page. It should be used by portlets written to the JSR-168 APIs; an analogous interface called <code>com.ibm.wps.pb.service.PropertyBrokerContextPassingService</code> exists for use by portlets written to the IBM portlet API. <p> The <code>PropertyBrokerContextPassingService</code> interface is implemented by a <code>PortletService</code>. A portlet can obtain the service by using JNDI. A boolean guard may be used to guard uses of the <code>PropertyFactory</code> by the portlet; this will enable the portlet to execute correctly in JSR-168 compliant portlet containers outside of WebSphere Portal.
