Constructor Detail

RootContainer

public RootContainer()

Method Detail

getOSEnvironment

public OperatingSystemInfo getOSEnvironment()

isPortalContainerConfigAware

public boolean isPortalContainerConfigAware()

Indicates if the current instance is aware of the PortalContainerConfig

Returns:

true if we are using the old way to configure the portal containers, false otherwise

getServerEnvironment

public J2EEServerInfo getServerEnvironment()

getComponentInstance

public Object getComponentInstance(Object componentKey)
                            throws org.picocontainer.PicoException

Specified by:

getComponentInstance in interface org.picocontainer.PicoContainer

Overrides:

getComponentInstance in class CachingContainer

Throws:

org.picocontainer.PicoException

getPortalContainer

public PortalContainer getPortalContainer(String name)

registerPortalContainer

public void registerPortalContainer(javax.servlet.ServletContext context)

Register a new portal container. It will try to detect if PortalContainerDefinition has been defined, if so it will create the portal container later otherwise we assume that we expect the old behavior, thus the portal container will be initialized synchronously

Parameters:

context - the context of the portal container

createPortalContainers

public void createPortalContainers()

Creates all the portal containers that have been registered thanks to the method registerPortalContainer

onEvent

public void onEvent(org.gatein.wci.WebAppEvent event)

Specified by:

onEvent in interface org.gatein.wci.WebAppListener

onEvent

public void onEvent(org.gatein.wci.authentication.AuthenticationEvent evt)

Specified by:

onEvent in interface org.gatein.wci.authentication.AuthenticationListener

createPortalContainer

public void createPortalContainer(javax.servlet.ServletContext context)

Create the portal container

Parameters:

context - the servlet context

removePortalContainer

public void removePortalContainer(javax.servlet.ServletContext servletContext)

Removes the portal container

Parameters:

servletContext - the servlet context

getComponent

public static Object getComponent(Class key)

getInstance

public static RootContainer getInstance()

Get the unique instance of the root container per VM. The implementation relies on the double checked locking pattern to guarantee that only one instance will be initialized. See

Returns:

the root container singleton

setInstance

public static void setInstance(RootContainer rcontainer)

Set the unique instance of the root container

Parameters:

rcontainer - the root container

getConfigurationXML

public String getConfigurationXML()

Returns:

the configuration of the container in XML format

reload

public void reload()

Makes the RootContainer reloads itself and all the portal containers

reload

public void reload(String portalContainerName)

Makes the RootContainer reloads only a given portal container

addInitTask

public void addInitTask(javax.servlet.ServletContext context,
                        RootContainer.PortalContainerInitTask task)

Calls the other method addInitTask with ServletContext.getServletContextName() as portal container name

Parameters:

context - the servlet context from which the task comes from

task - the task to add

addInitTask

public void addInitTask(javax.servlet.ServletContext context,
                        RootContainer.PortalContainerInitTask task,
                        String portalContainer)

First check if the related portal container has already been initialized. If so it will call the method onAlreadyExists on the given task otherwise the task will be added to the task list to execute during the related portal container initialization

Parameters:

context - the servlet context from which the task comes from

task - the task to add

portalContainer - the name of the portal container on which the task must be executed

stop

public void stop()

Description copied from class: ConcurrentPicoContainer

Stop the components of this PicoContainer and all its logical child containers. Any component implementing the lifecycle interface Startable will be stopped.

Specified by:

stop in interface org.picocontainer.Startable

Overrides:

stop in class ExoContainer
