Question

If I want to create more than one instance of managed bean in JSF 2.0, under different names in the same scope, how should I proceed? Ideally, I want the equivilant to (for example):

@ManagedBeans({name="myManagedBean1",name="myManagedBean2"})
@RequestScoped
public class MyManagedBean {

}

Thanks ..

You can’t. It technically also doesn’t make much sense. You’re probably looking for a solution in the wrong direction for the particular functional requirement.

Your best bet is to have a parent bean and have those “multiple beans” as children.

@ManagedBean
@RequestScoped
public class Parent {
    private Child child1;
    private Child child2;
    // ...
}

so that you can access it by #{parent.child1} and #{parent.child2}. You can of course also use a List<Child> property or even Map<String, Child> instead to be more flexible.

With the faces-config.xml it’s however possible to define multiple bean classes with a different name. Still then, I don’t see how that’s useful.
