Java Reference
In-Depth Information
Any instance of the bean that utilizes a producer method or field, disposer method or field, or
observer method invocation can service only that invocation.
Any injections of the bean into method parameters of disposer or observer methods exist to
service that method invocation only.
Going back to the example that was previously demonstrated using the @New qualifier, the same results can be
achieved using the following code:
@Dependent
public class Order (){
...
@Produces @ConversationScoped
Order getOrder(Order order){
...
}
...
}
