public abstract class Application extends Object
Application represents a per-web-application singleton object where applications based on Jakarta Server Faces (or implementations wishing to provide extended functionality) can register application-wide singletons that provide functionality required by Jakarta Server Faces. Default implementations of each object are provided for cases where the application does not choose to customize the behavior.
The instance of Application
is created by calling the getApplication()
method of ApplicationFactory
. Because this instance is shared, it must be implemented in
a thread-safe manner.
The application also acts as a factory for several types of Objects specified in the Faces
Configuration file. Please see createComponent(java.lang.String)
,
createConverter(java.lang.String)
, and createValidator(java.lang.String)
.

public abstract ActionListener getActionListener()
Return the default ActionListener
to be
registered for all ActionSource
components in this application.
If not explicitly set, a default implementation must be provided that performs the
functions as specified in the section titled
"ActionListener Property" in the chapter titled "Application Integration" of the spec prose
document.
Note that the specification for the default ActionListener
contiues to call for
the use of a deprecated property (action
) and class
(MethodBinding
). Unfortunately, this is necessary because the default
ActionListener
must continue to work with components that do not implement
ActionSource2
, and only implement
ActionSource
.

Set the default ActionListener
to be registered for all
ActionSource
components.

Set the renderKitId
to be used to render this application. Unless the client has
provided a custom ViewHandler
that supports the use of multiple
RenderKit

implementation of ResourceHandler
.
The ResourceHandler
implementation is declared in the application configuration
resources by giving the fully qualified class name as the value of the
<resource-handler>
element within the <application>
element.
In all of the above cases, the runtime must employ the decorator pattern as for every other pluggable artifact in Jakarta Server Faces.
A default implementation is provided that throws UnsupportedOperationException
so that users that decorate Application
can continue to function
public void setResourceHandler(ResourceHandler resourceHandler)
Set the ResourceHandler
instance that will be utilized for rendering the markup for

public abstract PropertyResolver getPropertyResolver()
getELResolver()
.
Return a PropertyResolver
instance that wraps the ELResolver
instance that
Faces provides to the Jakarta Expression Language for the resolution of expressions that appear
programmatically in an application.
Note that this no longer returns the default PropertyResolver
since that class
is now a no-op that aids in allowing custom PropertyResolver
s to affect the EL
resolution process.

to be wrapped inside an implementation of
ELResolver
and exposed to the Jakarta Expression Language resolution system as if the user had
called addELResolver(javax.el.ELResolver)
.
Set the PropertyResolver
instance that will be utilized to resolve method and value
bindings.
This method is now deprecated but the implementation must cause the argument to be set as the
head of the legacy PropertyResolver
chain, replacing any existing value that was
set from the application configuration resources.
It is illegal to call this method after the application has received any requests from the client. If an attempt is made to register a listener after that time it must have no effect.

is null
IllegalStateException
- if called after the first request to the

as defined in the application configuration resources
under the specified name. If a ResourceBundle
was defined for the name, return
an instance that uses the locale of the current UIViewRoot
.
The default implementation throws UnsupportedOperationException
and is provided
for the sole purpose of not breaking existing applications that extend this class.

- if a bundle was defined, but not resolvableNullPointerException
- if ctx == null || name == nullpublic ProjectStage getProjectStage()
Return the project stage for the currently running application instance. The default value is
ProjectStage.Production
The implementation of this method must perform the following algorithm or an equivalent with the same end result to determine the value to return.
If the value has already been determined by a previous call to this method, simply return that value.
Look for a
JNDI
environment entry under the key given by the value ofProjectStage.PROJECT_STAGE_JNDI_NAME
(return type ofjava.lang.String
). If found, continue with the algorithm below, otherwise, look for an entry in theinitParamMap
of theExternalContext
from the currentFacesContext
with the key given by the value ofProjectStage.PROJECT_STAGE_PARAM_NAME
If a value is found, see if an enum constant can be obtained by calling
ProjectStage.valueOf()
, passing the value from theinitParamMap
. If this succeeds without exception, save the value and return it.If not found, or any of the previous attempts to discover the enum constant value have failed, log a descriptive error message, assign the value as
ProjectStage.Production
and return it.
A default implementation is provided that throws UnsupportedOperationException
so that users that decorate Application
can continue to function
public abstract VariableResolver getVariableResolver()
getELResolver()
.
Return the VariableResolver
that wraps the ELResolver
instance that Faces
provides to the Jakarta Expression Language for the resolution of expressions that appear programmatically in
an application. The implementation of the VariableResolver
must pass
null
as the base argument for any methods invoked on the underlying
ELResolver
.
Note that this method no longer returns the default VariableResolver
, since that
class now is a no-op that aids in allowing custom VariableResolver
s to affect
the Jakarta Expression Language resolution process.
public abstract void setVariableResolver(VariableResolver resolver)
<el-resolver>
element at the
right place in the application configuration resources which will be considered
in the normal course of expression evaluation. This method now will cause the
argument resolver
to be wrapped inside an implementation of
ELResolver
and exposed to the Jakarta Expression Language resolution system as if the user had
called addELResolver(javax.el.ELResolver)
.
Set the VariableResolver
instance that will be consulted to resolve method and value
bindings.
This method is now deprecated but the implementation must cause the argument to be set as the
head of the legacy VariableResolver
chain, replacing any existing value that was
set from the application configuration resources.
It is illegal to call this method after the application has received any requests from the client. If an attempt is made to register a listener after that time it must have no effect.
resolver
- The new VariableResolver
instanceNullPointerException
- if resolver
is null
IllegalStateException
- if called after the first request to the
FacesServlet
has been serviced.public void addELResolver(ELResolver resolver)
Cause an the argument resolver
to be added to the resolver chain as specified in section JSF.5.5.1 of the Jakarta Server Faces
Specification.
It is not possible to remove an ELResolver
registered with this method, once it
has been registered.
It is illegal to register an ELResolver
after the application has received any
requests from the client. If an attempt is made to register a listener after that time, an
IllegalStateException
must be thrown. This restriction is in place to allow the
Jakarta Server Pages container to optimize for the common case where no additional ELResolver
s
are in the chain, aside from the standard ones. It is permissible to add
ELResolver
s before or after initialization to a CompositeELResolver
that is already in the chain.
The default implementation throws UnsupportedOperationException
and is provided
for the sole purpose of not breaking existing applications that extend Application
.
resolver
- the Jakarta Expression Language resolver to add.IllegalStateException
- if called after the
first request to the FacesServlet
has been
serviced.public ELResolver getELResolver()
Return the singleton ELResolver
instance to be used for all Jakarta Expression Language resolution. This is
actually an instance of CompositeELResolver
that must contain the following
ELResolver
instances in the following order:
ELResolver
instances declared using the <el-resolver> element in the
application configuration resources.
An implementation
that wraps the head of the legacy
VariableResolver
chain, as per section VariableResolver ChainWrapper in
Chapter JSF.5 in the spec document.
An implementation
that wraps the head of the legacy
PropertyResolver
chain, as per section PropertyResolver ChainWrapper in
Chapter JSF.5 in the spec document.
Any ELResolver
instances added by calls to addELResolver(javax.el.ELResolver)
.
The default implementation throws UnsupportedOperationException
and is provided
for the sole purpose of not breaking existing applications that extend Application
.
public FlowHandler getFlowHandler()
Return the thread-safe singleton FlowHandler
for this application. For
implementations declaring compliance with version 2.2 of the specification, this method must
never return null
, even if the application has no flows. This is necessary to enable
dynamic flow creation during the application's lifetime.
All implementations that declare compliance with version 2.2 of the specification must
implement this method. For the purpose of backward compatibility with environments that
extend Application
but do not override this method, an implementation is provided that returns
null
. Due to the decoratable nature of Application
, code calling this method
should always check for a null
return.
public void setFlowHandler(FlowHandler newHandler)
Set the FlowHandler
instance used by the NavigationHandler
to satisfy the
requirements of the faces flows feature.

public UIComponent createComponent(FacesContext context, Resource componentResource)
Instantiate and return a new
UIComponent
instance from the argument Resource
. An algorithm semantically
equivalent to the following must be followed to instantiate the UIComponent
to
return.
Obtain a reference to the ViewDeclarationLanguage
for this Application
instance by calling ViewHandler.getViewDeclarationLanguage(javax.faces.context.FacesContext, java.lang.String)
, passing the
viewId
found by calling UIViewRoot.getViewId()
on
the UIViewRoot
in the argument FacesContext
.
Obtain a reference to the composite component metadata for this composite component
by calling ViewDeclarationLanguage.getComponentMetadata(javax.faces.context.FacesContext, javax.faces.application.Resource)
, passing the
facesContext
and componentResource
arguments to this method. This
version of the Jakarta Server Faces specification uses JavaBeans as the API to the component metadata.
Determine if the component author declared a componentType
for this component instance by
obtaining the BeanDescriptor
from the component metadata and calling its
getValue()
method, passing UIComponent.COMPOSITE_COMPONENT_TYPE_KEY
as
the argument. If non-null
, the result must be a ValueExpression
whose value is the component-type
of the UIComponent
to be created
for this Resource
component. Call through to
createComponent(java.lang.String)
to create the component.
Otherwise, determine if a script based component for this Resource
can be found
by calling ViewDeclarationLanguage.getScriptComponentResource(javax.faces.context.FacesContext, javax.faces.application.Resource)
. If the result is
non-null
, and is a script written in one of the languages listed in JSF.4.3 of
the specification prose document, create a UIComponent
instance from the script
resource.
Otherwise, let library-name be the return from calling
Resource.getLibraryName()
on the argument componentResource
and
resource-name be the return from calling Resource.getResourceName()
on the
argument componentResource
. Create a fully qualified Java class name by removing
any file extension from resource-name and let fqcn be
library-name + "." +
resource-name
. If a class with the name of fqcn cannot be found, take
no action and continue to the next step. If any of InstantiationException
,
IllegalAccessException
, or ClassCastException
are thrown, wrap the
exception in a FacesException
and re-throw it. If any other exception is thrown,
log the exception and continue to the next step.
If none of the previous steps have yielded a UIComponent
instance, call
createComponent(java.lang.String)
passing "javax.faces.NamingContainer
"
as the argument.
Call UIComponent.setRendererType(java.lang.String)
on the UIComponent
instance, passing
"javax.faces.Composite
" as the argument.
Store the argument Resource
in the attributes Map
of the
UIComponent
under the key, Resource.COMPONENT_RESOURCE_KEY
.
Store composite component metadata in the attributes Map
of the
UIComponent
under the key, UIComponent.BEANINFO_KEY
.
Before the component instance is returned, it must be inspected for the presence of a
ListenerFor
annotation. If this annotation is present, the action
listed in ListenerFor
must be taken on the component, before it is
returned from this method.
A default implementation is provided that throws UnsupportedOperationException
so that users that decorate Application
can continue to function.

If FacesContext.isProcessingEvents()
is true
and
there are one or more listeners for events of the type represented by
systemEventClass
, call those listeners, passing source
as the
source of the event. The implementation should be as fast as possible in determining whether
or not a listener for the given systemEventClass
and source
has
been installed, and should return immediately once such a determination has been made. The
implementation of publishEvent
must honor the requirements stated in
subscribeToEvent(java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Class<?>, javax.faces.event.SystemEventListener)
regarding the storage and retrieval of listener instances.
Specifically, if subscribeToEvent(Class,Class,SystemEventListener)
was called, the
sourceClass
argument must match exactly the Class
of the
source
argument in the call to publishEvent()
. The implementation
must not do any inheritance hierarachy inspection when looking for a match between the
sourceClass
passed to subscribeToEvent(Class,Class,SystemEventListener)
and the sourceClass
passed to publishEvent()
in order to find any
listeners to which the event should be published. In the case where the Class
of
the source
argument does not match the Class
of the
sourceClass
used when the listener was subscribed using
subscribeToEvent()
, publishEvent(FacesContext,Class,Class,Object)
can
be used to provide the Class
used to perform the listener lookup and match.
The default implementation must implement an algorithm semantically equivalent to the following to locate listener instances and to invoke them.
If the source
argument implements
SystemEventListenerHolder
, call
SystemEventListenerHolder.getListenersForEventClass(java.lang.Class<? extends javax.faces.event.SystemEvent>)
on it, passing
the systemEventClass
argument. If the list is not empty, perform algorithm
traverseListenerList on the list.
If any view level listeners have been installed by previous calls to
subscribeToEvent(Class, Class, javax.faces.event.SystemEventListener)
on the
UIViewRoot
, perform algorithm traverseListenerList on
the list of listeners for that event installed on the UIViewRoot
.
If any Application
level listeners have been installed by previous calls to
subscribeToEvent(Class, Class, javax.faces.event.SystemEventListener)
, perform
algorithm traverseListenerList on the list.
If any Application
level listeners have been installed by previous calls to
subscribeToEvent(Class, javax.faces.event.SystemEventListener)
, perform algorithm
traverseListenerList on the list.
If the act of invoking the processListener
method causes an
AbortProcessingException
to be thrown, processing of the listeners
must be aborted, no further processing of the listeners for this event must take place, and
the exception must be logged with Level.SEVERE
.
Algorithm traverseListenerList: For each listener in the list,
Call SystemEventListener.isListenerForSource(java.lang.Object)
, passing the
source
argument. If this returns false
, take no action on the
listener.
Otherwise, if the event to be passed to the listener instances has not yet been constructed,
construct the event, passing source
as the argument to the one-argument
constructor that takes an Object
. This same event instance must be passed to all
listener instances.
Call SystemEvent.isAppropriateListener(javax.faces.event.FacesListener)
, passing the listener
instance as the argument. If this returns false
, take no action on the listener.
Call SystemEvent.processListener(javax.faces.event.FacesListener)
, passing the listener instance.
