PortletService
To enable portlets to use pluggable services via dynamic discovery, the Portlet API provides the PortletService interface. A PortletService is accessed from the PortletContext.getService() method that looks up the appropriate factory for the service, creates the service and returns it to the portlet.
A portlet service can be invoked only from within a portlet.
Various services may be implemented by different vendors, for example, a SearchService, LocationService, or a MailService. The following are some of the services are available with WebSphere Portal:
