Portlet services

Portlet services are used to provide common functionality to portlets. Each portlet service has its own service-specific interface for the functionality that it offers. WebSphere Portal Express supports portlet services for both IBM portlets and standard portlets:

• Standard portlets use a JNDI lookup to retrieve a PortletServiceHome object, which is used to retrieve a portlet service implementation.

• IBM portlets retrieve portlet services using the PortletContext.getService() method.

A portlet service can be invoked only from within a portlet.

Portlet service interfaces used by standard portlets are different from those used by IBM portlets. You can write a portlet service and register it in the portal, so that all portlets can use it. Various services may be implemented by different vendors, for example, a SearchService, LocationService, or a MailService. The following services are available with WebSphere Portal Express:

• ContentAccessService

• CredentialVaultService

• PropertyBrokerService

• Model SPI services

• PumaHome

• DynamicUIManagementFactoryService
