com.sun.portal.common.service .ServiceContainer

All known Subclasses:   com.sun.portal.common.service.impl .ServiceContainerImpl,
ServiceContainer
abstract public class ServiceContainer (Code)
A ServiceContainer is a singleton that manages a collection of ServiceContexts.
The container implementation class can be specified as a system property. If it's not specified the default container implementation will be used, com.sun.portal.common.service.impl.ServiceContainerImpl
The default container implementation has a DEFAULT_CONTEXT only. This context initializes all the services described in the service.xml file that has to be available in the root of the classpath.

author:

Field Summary
final public static String DEFAULT_CONTEXT
     String constant used to retrieve the default context of a container.
final public static String SERVICE_CONTAINER_CLASS
     String constant that defined the system propoperty that it will be queried to obtain the name of the ServiceContainer class to use.

Method Summary
abstract public void destroy()
     Destroys the ServiceContainer object.
This method must be called to take the container out of service.
public static ServiceContainer getContainer()
     Return the ServiceContainer object.
abstract public ServiceContext getContext(String name)
     Returns the named ServiceContext of the container.
If the DEFAULT_CONTEXT constant is used, the default context must be returned.
abstract public void init()
     Initializes the ServiceContainer object.

Field Detail
DEFAULT_CONTEXT
final public static String DEFAULT_CONTEXT(Code)
String constant used to retrieve the default context of a container.

SERVICE_CONTAINER_CLASS
final public static String SERVICE_CONTAINER_CLASS(Code)
String constant that defined the system propoperty that it will be queried to obtain the name of the ServiceContainer class to use.
It's value is com.sun.portal.common.service.container.class

Method Detail
destroy
abstract public void destroy()(Code)
Destroys the ServiceContainer object.
This method must be called to take the container out of service. After this method completes, the container is not active anymore.
This method gives the container an opportunity to clean up any resources that are being held (for example, memory, file handles, threads).

getContainer
public static ServiceContainer getContainer()(Code)
Return the ServiceContainer object.
the ServiceContainer object

getContext
abstract public ServiceContext getContext(String name)(Code)
Returns the named ServiceContext of the container.
If the DEFAULT_CONTEXT constant is used, the default context must be returned. A container always has a default context.

Parameters:
  name - a String containing the name of the contextto retrieve the ServiceContext with the given name, or nullif the context does not exist

init
abstract public void init() throws ServiceException(Code)
Initializes the ServiceContainer object.
This method must be called before any ServiceContext can be retrieved from the container. The init method must complete successfully in order for the container to be operational.

throws:
  ServiceException - if an exception has occurredthat interferes with the container's normalinitialization
