LifecycleFactory and implement the following methods:
EAN13 Drawer In Java
Using Barcode maker for Java Control to generate, create EAN 13 image in Java applications.
UPC-A Maker In Java

Create Barcode In Java
Using Barcode encoder for Java Control to generate, create bar code image in Java applications.
Like the RenderKitFactory, the LifecycleFactory maintains a Map of lifecycleIds to Lifecycle instances In order to take advantage of using a custom LifecycleFactory, you must examine the API of the Lifecycle class

European Article Number 13 Printer In None
Using Barcode creator for Font Control to generate, create EAN-13 Supplement 5 image in Font applications.
The first three methods are simply an implementation of a JavaBeans listener property for PhaseListener The execute( ) method is responsible for running the postback part of the lifecycle, as described in 3 The render( ) method is responsible only for rendering
Code 39 Drawer In None

development of the specification we realized that a postback to a Portlet limited the postback portion of the request processing lifecycle to only the one Portlet in the page that actually is experiencing the form submit, while every Portlet in the page must re-render itself Breaking these out into two separate phases allowed this design to be possible
Please see 3 for details on the request processing lifecycle, which will give you insight into ways to provide your own implementation, if desired Finally, note that LifecycleFactory implements FacesWrapper, making it easier to decorate the existing lifecycle
JSF 12 TIP In JSF 12, Expert Group member Jacob Hookom, inventor of Facelets, introduced a
new way to specify the lifecycleId for an application with a potential use in AJAX applications: having a different lifecycle for different FacesServlet instances in the same application Prior to JSF 12, every FacesServlet in a single Web application was required to share the same LifecycleFactory and therefore the same kind of lifecycle This was because the only way to specify an alternate lifecycle was through a lifecycleId context-param in the faces-configxml file Jacob s idea was to also allow an init-param element to contain a lifecycleId By doing this, it s possible to write a custom Lifecycle implementation that is optimized for handling AJAX requests and responses

Building Non-UI Custom Components
PartialViewContextFactory
Decorating this class allows you to affect how the runtime processes partial traversals of the view, most importantly during Ajax requests
Abstract Class to Extend
A custom PartialViewContextFactory must extend the class javaxfacescontextPartialViewContextFactory and implement the following method:
public PartialViewContext getPartialViewContext(FacesContext context);
This class implements FacesWrapper, so really it s only necessary to override the getWrapped( ) method as shown in the introductory section on decoration It is convenient to use the inner class decorator pattern shown in the section ExceptionHandlerFactory to implement the getPartialViewContext( ), as shown here:
public class MyPartialViewContextFactory extends PartialViewContextFactory { private PartialViewContextFactory parent; public MyPartialViewContextFactory(PartialViewContextFactory parent) { thisparent = parent; } public PartialViewContextFactory getWrapped( ) { return thisparent; } public PartialViewContext getPartialViewContext(FacesContext context) { final PartialViewContext parentContext = getWrapped( ) getPartialViewContext( ); PartialViewContext result = new PartialViewContextWrapper( ) { public PartialViewContext getWrapped( ) { return parentContext; } // implement as many or as few methods from // PartialViewContext }; }
PART II
The class PartialViewContext has methods that control nearly every aspect of how Ajax requests are processed Please see 12 for a more detailed discussion of Ajax and JSF
ViewDeclarationLanguageFactory
Decorating this class allows you to affect how the runtime takes an input file and produces a tree of UIComponent instances against which the JSF lifecycle can be run
Abstract Class to Extend A custom ViewDeclarationLanguageFactory must extend the class
javaxfacesviewViewDeclarationLanguageFactory and implement the following method:
public ViewDeclarationLanguage getViewDeclarationLanguage(String viewId);
This class implements FacesWrapper, so really it s only necessary to override the getWrapped( ) method as shown in the introductory section on decoration It is convenient
