Component

A component can reference another component by retrieving an IPortalComponentContext object for the component from the IPortalComponentRequest object, as in the following example:

request.getComponentContext("myApplication.myComp");

The above example gets a reference to the myComp component defined in the myApp application. You can use the object, for example, to add a component to the POM tree, or to get information and resources from the component.

Service

A component or service can reference a service by retrieving an IService object for the service. The IService object can then be cast into the interface for the corresponding service.

PortalRuntime.getRuntimeResources().getService( ITransformerService.KEY);

The above example gets a reference to the transformation service. PortalRuntime is a member of the com.sapportals.portal.prt.runtime package.

Resource

A component can reference a Web resource packaged in its application or in another application by retrieving an IResource object for the resource from the IPortalComponentRequest object, as in the following examples:

A component can use a Web resource, for example, to create a link to the resource or to include it in its content.

Property (component)

A component can reference one of its profile properties, which are defined in <property> elements in the <component-profile> element in the component's deployment descriptor.

You can also access properties defined by the semantic object in which the component is running. For example, if the component is run as an iView, the iView semantic object defines properties, such as com.sap.portal.pcm.Title for the iView's name.

The property value is first defined in the deployment descriptor, and then can be modified by an administrator for the specific iView, and then can be modified by the current user if the property is defined as personalizable.

The following retrieves the value of myProperty:

IPortalComponentProfile profile = request.getComponentContext().getProfile(); String propertyValue = profile.getProperty("myProperty");

The properties defined in the <component-config> element cannot be referenced.

Property (service)

A service can reference one of its profile properties, which are defined in <property> elements in the <service-profile> element in the component's deployment descriptor, within the service's init() method.

The init() method is passed a IServiceContext object, which you can use as follows to retrieve a property value:.

String propertyValue = serviceContext.getServiceProfile().getProperty("myProperty");
