@StableMinor(version="12.2", sinceVersion="4.0") public interface IServiceInterface
ServiceInterface
interface is used by the service interface container to
invoke the service interfaces. Every service interface has to implement this interface, either by
directly implementing it, or by using an existing class implementing the ServiceInterface
interface.
A service interface is a Java technology-based web component. It is managed by the service interface container and processes requests and generates dynamic content as response. ServiceInterfaces are used by portals as pluggable user interface components.
The content generated by a service interface is called a fragment. A fragment is a piece of markup (e.g. HTML, XHTML, WML) adhering to certain rules and can be aggregated with other fragments into a complete document. The content of a service interface is normally aggregated with the content of other service interfaces into the portal page.
The service interface container instanciates service interfaces, manages their lifecycle and invoking them to process requests. The lifecycle consists of:
init
method
destroy
method
Request processing is divided into two types:
processAction
method, to perform actions
targeted to the service interface
render
method, to perform the render
operation
Modifier and Type | Method and Description |
---|---|
void |
instanceAdded(ServiceInterfaceInstanceConfig config,
ITransaction transaction)
Called by the service container to indicate that a service interface instance has been added
|
void |
instanceDeleted(ServiceInterfaceInstanceConfig config)
Called by the service container to indicate that a service interface instance has been
deleted
|
void |
instanceLoaded(ServiceInterfaceInstanceConfig config) |
void |
instanceUnLoaded(ServiceInterfaceInstanceConfig config)
Called by the service container to indicate that a service interface instance is about to be
destroyed
|
void |
load(ServiceInterfaceConfig config)
Called by the service interface container to indicate to a service interface that the service
interface is being placed into service.
|
void |
processAction(IServiceInterfaceActionRequest request,
IServiceInterfaceActionResponse response)
Called by the service interface container to allow the service interface to process an action
request.
|
void |
register(SessionConfig sessionConfig,
Node serviceInterfaceXmlNode,
ITransaction transaction)
Called by the service interface manager when a service interface definition is registered.
|
void |
render(IServiceInterfaceRenderRequest request,
IServiceInterfaceRenderResponse response)
Called by the service interface container to allow the service interface to generate the
content of the response based on its current state.
|
void |
renderBefore(IServiceInterfaceRenderRequest request,
IServiceInterfaceRenderResponse response)
Called by the service interface container before rendering the interface client side.
|
void |
unload()
Called by the service interface container to indicate to a service interface that the service
interface is being taken out of service.

void load(ServiceInterfaceConfig config) throws ServiceInterfaceException, PortalException
The service interface container calls the init
method exactly once after
instantiating the service interface. The init
method must complete
successfully before the service interface can receive any requests.
The service interface container cannot place the service interface into service if the

Before the service interface container calls the destroy method, it should allow any threads that are currently processing requests within the service interface object to complete execution. To avoid waiting forever, the service interface container can optionally wait for a predefined time before destroying the service interface object.
This method enables the service interface to do the following:

Typically, in response to an action request, a service interface updates state based on the information sent in the action request parameters. In an action the service interface may:
A client request triggered by an action URL translates into one action request and many render requests, one per service interface in the portal page. The action processing must be finished before the render requests can be issued.
