javax.faces.application
Class Application

java.lang.Object
  extended by javax.faces.application.Application

public abstract class Application
extends 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).

Application

public Application()
Method Detail

getActionListener

public abstract ActionListener getActionListener()

Return the default ActionListener to be registered for all ActionSource components in this appication. If not explicitly set, a default implementation must be provided that performs the following functions:

  • The processAction() method must first call FacesContext.renderResponse() in order to bypass any intervening lifecycle phases, once the method returns.
  • The processAction() method must next determine the logical outcome of this event, as follows:
    • If the originating component has a non-null action property, retrieve the MethodBinding from the property, and call invoke() on it. Convert the returned value (if any) to a String, and use it as the logical outcome.
    • Otherwise, the logical outcome is null.
  • The processAction() method must finally retrieve the NavigationHandler instance for this application and call NavigationHandler.handleNavigation(javax.faces.context.FacesContext, java.lang.String, java.lang.String) passing:
    • the FacesContext for the current request
    • If there is a MethodBinding instance for the action property of this component, the result of calling MethodBinding.getExpressionString() on it, null otherwise
    • the logical outcome as determined above

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.

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:
NullPointerException - if listener is null

getDefaultLocale

public abstract Locale getDefaultLocale()

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

setDefaultLocale

public abstract void setDefaultLocale(Locale locale)

Set the default Locale for this application.

Parameters:
locale - The new default Locale
Throws:
NullPointerException - if locale is null

getDefaultRenderKitId

public abstract String getDefaultRenderKitId()

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

setDefaultRenderKitId

public abstract void setDefaultRenderKitId(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.

getMessageBundle

public abstract String getMessageBundle()

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

setMessageBundle

public abstract void setMessageBundle(String bundle)

Set the fully qualified class name of the ResourceBundle to be used for JavaServer 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:
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.

setNavigationHandler

public abstract void setNavigationHandler(NavigationHandler handler)

Set the NavigationHandler instance that will be passed the outcome returned by any invoked application action for this web application.

Parameters:
handler - The new NavigationHandler instance
Throws:
NullPointerException - if handler is null

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.

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:
NullPointerException - if resolver is null
IllegalStateException - if called after the first request to the FacesServlet has been serviced.

getResourceBundle

public ResourceBundle getResourceBundle(FacesContext ctx,
                                        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.

Returns:
ResourceBundle for the current UIViewRoot, otherwise null
Throws:
FacesException - if a bundle was defined, but not resolvable
NullPointerException - if ctx == null || name == null
Since:
1.2

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.

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:
NullPointerException - if resolver is null
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 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.

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 5 in the spec document.

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

Since:
1.2

getViewHandler
