our own defined Servlet class . 5. Servelt the relationship between core APIs UML diagram:6. The start of the servlet (default is a singleton servlet) (the Init method is executed the first time the servlet is called by default)• The servlet container loads the servlet at the following times:–servlet loading some servlets automatically when the container starts– After the servlet container is started, the customer makes the first request to the servletAfter the –servlet class file is updated,

properties.4. Build a new view based on the component tree.5. The view is presented as a response to the request client.6, the component tree is automatically destroyed.7. In the subsequent request, rebuild the component tree and apply the saved state.Examples of event processing in the JSF lifecycle:In a JSF application, the JSF implementation uses a controller servlet to process the request and then executes the JSF lifecycle. JSF is event-driven,

folder.3.2 Configuring the Application Server Xdoclet (optional)Xdoclet is able to generate server-specific deployment descriptors.Note: you will see later the steps for deploying FIRSTEJB to the local JBoss server, which use the JBoss subtasks.1. Right-click FIRSTEJB, select Properties, expand MyEclipse, and then select Xdoclet.2. Select the standard EJB to view the task, right-click Ejbdoclet, and select Add.3. Select JBoss, then click OK.4. Select JBoss subtask, double-click the Destdir prop
