  public Application()

Method Detail

• getActionListener

  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.

  Returns:

  the action listener.

• setActionListener

  public abstract void setActionListener(ActionListener listener)

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

  Parameters:

  listener - The new default ActionListener

  Throws:

  java.lang.NullPointerException - if listener is null

• getDefaultLocale

  public abstract java.util.Locale getDefaultLocale()

  Return the default Locale for this application. If not explicitly set, null is returned.

  Returns:

  the default Locale, or null.

• setDefaultLocale

  public abstract void setDefaultLocale(java.util.Locale locale)

  Set the default Locale for this application.

  Parameters:

  locale - The new default Locale

  Throws:

  java.lang.NullPointerException - if locale is null

• getDefaultRenderKitId

  public abstract java.lang.String getDefaultRenderKitId()

  Return the renderKitId to be used for rendering this application. If not explicitly set, null is returned.

  Returns:

  the default render kit id, or null.

• setDefaultRenderKitId

  public abstract void setDefaultRenderKitId(java.lang.String renderKitId)

  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 instances in the same application, this method must only be called at application startup, before any Faces requests have been processed. This is a limitation of the current Specification, and may be lifted in a future release.

  Parameters:

  renderKitId - the render kit id to set.

• getMessageBundle

  public abstract java.lang.String getMessageBundle()

  Return the fully qualified class name of the ResourceBundle to be used for Jakarta Server Faces messages for this application. If not explicitly set, null is returned.

  Returns:

  the message bundle class name, or null.

• setMessageBundle

  public abstract void setMessageBundle(java.lang.String bundle)

  Set the fully qualified class name of the ResourceBundle to be used for Jakarta Server Faces messages for this application. See the JavaDocs for the java.util.ResourceBundle class for more information about the syntax for resource bundle names.

  Parameters:

  bundle - Base name of the resource bundle to be used

  Throws:

  java.lang.NullPointerException - if bundle is null

• getNavigationHandler

  public abstract NavigationHandler getNavigationHandler()

  Return the NavigationHandler instance that will be passed the outcome returned by any invoked application action for this web application. If not explicitly set, a default implementation must be provided that performs the functions described in the NavigationHandler class description.

  • The NavigationHandler implementation is declared in the application configuration resources by giving the fully qualified class name as the value of the <navigation-handler> element within the <application> element.

  The runtime must employ the decorator pattern as for every other pluggable artifact in Jakarta Server Faces.

  Returns:

  the navigation handler.

  java.lang.NullPointerException - if handler is null

• getResourceHandler

  public ResourceHandler getResourceHandler()

  Return the singleton, stateless, thread-safe ResourceHandler for this application. The Jakarta Server Faces implementation must support the following techniques for declaring an alternate 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.

• getPropertyResolver

  public abstract PropertyResolver getPropertyResolver()

  Deprecated. This has been replaced by 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 PropertyResolvers to affect the EL resolution process.

  Returns:

  the property resolver.

• setPropertyResolver

  public abstract void setPropertyResolver(PropertyResolver resolver)

  Deprecated. The recommended way to affect the execution of the Jakarta Expression Language is to provide an <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 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.

  Parameters:

  resolver - The new PropertyResolver instance

  Throws:

  java.lang.NullPointerException - if resolver is null

  java.lang.IllegalStateException - if called after the first request to the FacesServlet has been serviced.

• getResourceBundle

  Find a ResourceBundle 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.

  Parameters:

  ctx - the Faces context.

  name - the name of the resource bundle.

  Returns:

  the resource bundle.

  Throws:

  FacesException - if a bundle was defined, but not resolvable

  java.lang.NullPointerException - if ctx == null || name == null

  Since:

  1.2

• getProjectStage

  public 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 of ProjectStage.PROJECT_STAGE_JNDI_NAME (return type of java.lang.String). If found, continue with the algorithm below, otherwise, look for an entry in the initParamMap of the ExternalContext from the current FacesContext with the key given by the value of ProjectStage.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 the initParamMap. 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

  .

  Returns:

  the project stage.

  Since:

  2.0

• getVariableResolver

  public abstract VariableResolver getVariableResolver()

  Deprecated. This has been replaced by 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 VariableResolvermust 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 VariableResolvers to affect the Jakarta Expression Language resolution process.

  Returns:

  the variable resolver.

• setVariableResolver

  public abstract void setVariableResolver(VariableResolver resolver)

  Deprecated. The recommended way to affect the execution of the Jakarta Expression Language is to provide an <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.

  Parameters:

  resolver - The new VariableResolver instance

  Throws:

  java.lang.NullPointerException - if resolver is null

  java.lang.IllegalStateException - if called after the first request to the FacesServlet has been serviced.

• addELResolver

  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 ELResolvers are in the chain, aside from the standard ones. It is permissible to add ELResolvers 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.

  Parameters:

  resolver - the Jakarta Expression Language resolver to add.

  Throws:

  java.lang.IllegalStateException - if called after the first request to the FacesServlet has been serviced.

  Since:

  1.2

• getELResolver

  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:

  1. ELResolver instances declared using the <el-resolver> element in the application configuration resources.

  2. An implementation that wraps the head of the legacy VariableResolver chain, as per section VariableResolver ChainWrapper in Chapter JSF.5 in the spec document.

  3. An implementation that wraps the head of the legacy PropertyResolver chain, as per section PropertyResolver ChainWrapper in Chapter JSF.5 in the spec document.

  4. 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.

  Returns:

  the Jakarta Expression Language resolver.

  Since:

  1.2

• getFlowHandler

  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.

  Returns:

  the flow handler.

  Since:

  2.2

• setFlowHandler

  public void setFlowHandler(FlowHandler newHandler)

  Set the FlowHandler instance used by the NavigationHandler to satisfy the requirements of the faces flows feature.

• createComponent

  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.

  Parameters:

  context - FacesContext for the current request

  componentResource - A Resource that points to a source file that provides an implementation of a component.

  Returns:

  the UI component.

  Throws:

  FacesException - if a UIComponent from the Resource cannot be created

  To locate an appropriate Converter class, the following algorithm is performed, stopping as soon as an appropriate Converter class is found:

  • Locate a Converter registered for the target class itself.
  • Locate a Converter registered for interfaces that are implemented by the target class (directly or indirectly).
  • Locate a Converter registered for the superclass (if any) of the target class, recursively working up the inheritance hierarchy.

  If the Converter has a single argument constructor that accepts a Class, instantiate the Converter using that constructor, passing the argument targetClass as the sole argument. Otherwise, simply use the zero-argument constructor.

  If the toLowerCase() of the String represenation of the value of the "javax.faces.DATETIMECONVERTER_DEFAULT_TIMEZONE_IS_SYSTEM_TIMEZONE" application configuration parameter is "true" (without the quotes) and the Converter instance to be returned is an instance of DateTimeConverter, DateTimeConverter.setTimeZone(java.util.TimeZone) must be called, passing the return from TimeZone.getDefault().

  Parameters:

  targetClass - Target class for which to return a Converter

  Returns:

  the converter.

  Throws:

  FacesException - if the Converter cannot be created

  java.lang.NullPointerException - if targetClass is null

• publishEvent

  public void publishEvent(FacesContext context,
                           java.lang.Class<? extends SystemEvent> systemEventClass,
                           java.lang.Object source)

  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.

  A default implementation is provided that throws UnsupportedOperationException so that users that decorate Application can continue to function

  .

  Parameters:

  context - the FacesContext for the current request

  systemEventClass - The Class of event that is being published.

  source - The source for the event of type systemEventClass.

  Throws:

  java.lang.NullPointerException - if either context, systemEventClass or source is null

                           java.lang.Object source)

  This method functions exactly like publishEvent(FacesContext,Class,Object), except the run-time must use the argument sourceBaseType to find the matching listener instead of using the Class of the source argument.

  A default implementation is provided that throws UnsupportedOperationException so that users that decorate Application can continue to function

  .

  Parameters:

  context - the FacesContext for the current request

  systemEventClass - The Class of event that is being published.

  sourceBaseType - The Class of the source event that must be used to lookup the listener to which this event must be published. If this argument is null the return from source.getClass() must be used as the sourceBaseType.

                               SystemEventListener listener)

  Install the listener instance referenced by argument listener into the application as a listener for events of type systemEventClass that originate from objects of type sourceClass.

  If argument sourceClass is non-null, sourceClass and systemEventClass must be used to store the argument listener in the application in such a way that the listener can be quickly looked up by the implementation of publishEvent(javax.faces.context.FacesContext, java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Object) given systemEventClass and an instance of the Class referenced by sourceClass. If argument sourceClass is null, the listener must be discoverable by the implementation of publishEvent(javax.faces.context.FacesContext, java.lang.Class<? extends javax.faces.event.SystemEvent>, java.lang.Object) given only systemEventClass.

  It is valid to call this method during the processing of an event which was subscribed to by a previous call to this method.

  Parameters:

  systemEventClass - the Class of event for which listener must be fired.

  sourceClass - the Class of the instance which causes events of type systemEventClass to be fired. May be null.

  listener - the implementation of SystemEventListener whose SystemEventListener.processEvent(javax.faces.event.SystemEvent) method must be called when events of type systemEventClass are fired.
