JAVA SERVER FACES USING ANNOTATION

Using Annotation 


@ManagedBean(name = "helloWorld", eager = true) 
@RequestScoped 
public class HelloWorld { 
  
   @ManagedProperty(value="#{message}") 
   private Message message; 

@ManagedBean Annotation 


@ManagedBean marks a bean to be a managed bean with 
the name specified in name attribute. If the name 
attribute is not specified, then the managed bean 
name will default to class name portion of the fully 
qualified class name. In our case it would be helloWorld. 
Another important attribute is eager. If eager="true" 
then managed bean is created before it is requested 
for the first time otherwise "lazy" initialization is 
used in which bean will be created only when it is requested.
