⚠️ usually common users of MyFaces Core does not need to deal with these specific stuff, because the application/web server could already provide the necessary hooks or integration modules "out of the box"
MyFaces core provides some "points of integration" that can be used by application and web servers to override or add some specific code. For example, JBoss AS provides a custom virtual file system (VFS), and MyFaces core needs to scan for faces-config.xml files, so it is necessary to provide some code that uses JBoss VFS to locate faces-config.xml files to be parsed later.
Some features uses Service Provider Interface (SPI) pattern, so take a look at java.util.ServiceLoader description in java 6 api to get the idea how it works.
Below there is a table of the "points of integration" used by application and web servers:
| Integration Point | Classes Involved | Description | Since |

Get all org.apache.myfaces.config.element.FacesConfig data and then it combines it into one org.apache.myfaces.config.element.FacesConfigData instance. | 2.0.3, 2.1.0 |
| Get configuration information from different sources and allow cache them. | org.apache.myfaces.spi.FacesConfigurationProvider org.apache.myfaces.spi.FacesConfigurationProviderFactory org.apache.myfaces.config.element.* |
This interface provide a way to merge and store all JSF config information retrieved from faces-config.xml files, META-INF/service files and annotations that works as base point to initialize MyFaces. The objective is allow server containers to "store" or this information, preventing calculate it over and over each time the web application is started. | 2.0.3, 2.1.0 |
| Override javax.faces.FactoryFinder default algorithm | org.apache.myfaces.spi.FactoryFinderProvider org.apache.myfaces.spi.FactoryFinderProviderFactory |
Provide an interface to override javax.faces.FactoryFinder class methods. This is useful if containers does not want to use Thread Context Class Loader to load classes, like in OSGi. | 2.0.5, 2.1.0 |
| Provide additional info from web.xml files | org.apache.myfaces.spi.WebConfigProvider org.apache.myfaces.spi.WebConfigProviderFactory org.apache.myfaces.spi.ServletMapping |
Provide additional info from web.xml files, like mapping or if an error page is present. | 2.0.3, 2.1.0 |
| Override initialization and destroy web applications | org.apache.myfaces.webapp.FacesInitializer org.apache.myfaces.webapp.FacesInitializerFactory |
Allow customize initialization / destroy operations or provide an alternate MyFaces initializer to a specific container. | 2.0.1, |
| Scan for annotated Flows and manage Flow scope | org.apache.myfaces.spi.FacesFlowProvider org.apache.myfaces.spi.FacesFlowProviderFactory |
In this interface @FlowDefinition annotation is scanned for flows defined programatically and it is also managed the flow scope logic. By default MyFaces provides two implementations, one using CDI and one without CDI (that only manages flow scope) | 2.2.0 |
| Manage View scope | org.apache.myfaces.spi.ViewScopeProvider org.apache.myfaces.spi.ViewScopeProviderFactory |
This interface manage the logic to plug the view scope with JSF. It has some methods to handle view scope destroy or session destroy | 2.2.0 |
| Scan for available contracts | org.apache.myfaces.spi.ResourceLibraryContractsProvider org.apache.myfaces.spi.ResourceLibraryContractsProviderFactory |
Provides an interface to scan for the available resource library contracts in the current environment. By default it scans using external context getResource(...) methods and in the classpath according to JSF spec. | 2.2.0 |
