Info

Attention: There are other methods that you can override as well, like reportErrors(). However, there are two methods that are useless to override: processUpdateModel(), and processComponentEvents(). These methods are never called in a JSF context., because they provide functionality that is part of the standard JSF Lifecyle: • The JSF Update Model phase provides the same functionality as processUpdateModel(). • The JSF Invoke Application phase provides the same functionality as processComponentEvents(). The methods are there because the FacesPageLifecycle class extends a generic PageLifecycle class that is also used when building web applications without JSF. For example, when using Struts the ADF framework does call these methods. JHeadstart Developer’s Guide JSF-ADF Page Lifecycle 14 - 7
14.3. JHeadstart Page Lifecycle The JHeadstart Runtime includes its own lifecycle class oracle.jheadstart.controller.jsf.lifecycle.JhsPageLifecycle that subclasses oracle.adf.controller.faces.lifecycle.FacesPageLifecycle. As you will expect after reading the previous section, JHeadstart registers the JhsPageLifecycle class using its own Phase Listener class, JhsADFPhaseListener. When you generate your application with JHeadstart, the following entry is generated into a faces-config file named JhsCommon-beans.xml: oracle.jheadstart.controller.jsf.lifecycle.JhsADFPhaseListener Attention: JHeadstart generates multiple faces-config files, to nicely organize the various elements that can be recorded in a faces-config file. You can set the names or directories of these files through service-level properties in the Application Definition, here is the list if you keep the default settings: • The JhsCommon-beans.xml faces config contains the above element, as well as generic bean definitions that are common to the whole web application. Even when you have multiple application definitions to generate your application, you still need only one JhsCommon-beans.xml. • The “Main” faces-config.xml contains the navigation rules of your service (application definition). You can have multiple Application Definitions generated into the same faces-config.xml, or in different files when you change the Service-level property Main Faces Config. • The “Group” faces-config files hold all the managed bean definitions used by the pages generated for a specific group. • The Breadcrumb faces-config holds all the breadcrumb managed bean definitions for one service (application definition). Of course, JSF needs to know it should load all these generated faces-config files. This is handled by a element named javax.faces.CONFIG_FILES in the web.xml, which contains a commadelimited list of all faces-config files. If this context parameter does not exist, JSF only loads the default faces-config, which should be named facesconfig.xml, located in the WEB-INF folder. If you go to the source of the JhsADFPhaseListener class, you will see the following method: protected PageLifecycle createPageLifecycle() { return (PageLifecycle)JsfUtils.getExpressionValue("#{jhsPageLifecycle}"); } Rather than hardcoding the instantiation of a specific PageLifecycle class, as is done in the default ADFPhaseListener class (see previous section), JHeadstart uses a very powerful JSF technique: you can get hold of any java class defined as a managed bean, by using the same sort of EL expression as you use in your JSP pages to reference managed beans. The above expression will return an instance of the class that is defined 14 - 8 JSF-ADF Page Lifecycle JHeadstart Developer’s Guide
