Examples of com.sun.faces.spi.ManagedBeanFactory

com.sun.faces.spi.ManagedBeanFactory
some action after the instantiation of every managed // bean, for example, notify a bean lifecycle listener. Scope scope = parent.getScope(); if (scope == Scope.SESSION) { // Take some action involving an HttpSessionListener // to call a lifecycle method when the session is destroyed } else if (scope == Scope.REQUEST) { // Take some action involving an ServletRequestListener // to call a lifecycle method when the session is destroyed } else if (scope == Scope.APPLICATION) { // Take some action involving a ServletContextListener to call // a lifecycle method when the application is destroyed. } } }
This example shows how you can provide a simple class that hooks into the managed bean creation lifecycle to provide a lifecycle notification scheme.
