Class Application

  • Direct Known Subclasses:
    ApplicationWrapper

    public abstract class Application
extends java.lang.Object

    Application represents a per-web-application singleton object where applications based on JavaServer Faces (or implementations wishing to provide extended functionality) can register application-wide singletons that provide functionality required by JavaServer 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).

    • 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.

        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​()

      • 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 JSF.

        Returns:

        Return the singleton, stateless, thread-safe ResourceHandler for this application. The JSF 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 JSF.

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

        .
        Returns:
        the resource handler.
        Since:
        2.0

      • setResourceHandler

        public void setResourceHandler​(ResourceHandler resourceHandler)

        Set the ResourceHandler instance that will be utilized for rendering the markup for resources, and for satisfying client requests to serve up resources.

        Parameters:
        resourceHandler - The new ResourceHandler instance
        Throws:
        java.lang.IllegalStateException - if this method is called after at least one request has been processed by the Lifecycle instance for this application.

        Since:
        2.0

      • 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 unified EL 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 EL 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 EL 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

        public java.util.ResourceBundle getResourceBundle​(FacesContext ctx,
                                                  java.lang.String name)

        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 unified EL 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 EL resolution process.

        Returns:
        the variable resolver.

      • setVariableResolver

        public abstract void setVariableResolver​(VariableResolver resolver)
        Deprecated. The recommended way to affect the execution of the EL 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 EL 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 JavaServer 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 JSP 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 EL 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 EL 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 EL 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

        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().

        The argument converter must be inspected for the presence of the ResourceDependency annotation. If the ResourceDependency annotation is present, the action described in ResourceDependency must be taken. If the ResourceDependency annotation is not present, the argument converter must be inspected for the presence of the ResourceDependencies annotation. If the ResourceDependencies annotation is present, the action described in ResourceDependencies must be taken.

        Parameters:
        converterId - The converter id for which to create and return a new Converter instance
        Returns:
        the converter.
        Throws:
        FacesException - if the Converter cannot be created
        java.lang.NullPointerException - if converterId is null

      • createConverter

        public abstract Converter createConverter​(java.lang.Class<?> targetClass)

        Instantiate and return a new Converter instance of the class that has registered itself as capable of performing conversions for objects of the specified type. If no such Converter class can be identified, return null.

        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

        .
        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.
        source - The source for the event of type systemEventClass.
        Throws:
        java.lang.NullPointerException - if any arguments except for sourceBaseType are null

        Remove the listener instance referenced by argument listener from the application as a listener for events of type systemEventClass that originate from objects of type sourceClass. See subscribeToEvent(Class, Class, javax.faces.event.SystemEventListener) for the specification of how the listener is stored, and therefore, how it must be removed.

        See subscribeToEvent(java.lang.Class,java.lang.Class,javax.faces.event.SystemEventListener) for an additional requirement regarding when it is valid to call 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 to remove from the internal data structure.
        Throws:

        Parameters:
        resolver - the SearchKeywordResolver to add.
        Throws:
        java.lang.IllegalStateException - if called after the first request to the FacesServlet has been serviced.
