Question on The @EJB Annotaion

Question

Hello everyone,
How does the @EJB annotation works? Does it already assign an instance of the EJB once a field is annotated by it?
For example I have a code below;
public class MyClass {
    @EJB
    StudentEJB studentEJB;
    @EJB
    EmployeeEJB employeeEJB;
    public void process(int type) {
        switch(type) {
            case STUDENT:
                studentEJB.processRecord();
                break;
            case EMPLOYEE:
                employeeEJB.processRecord();
                break;
}From the code above, either one of the EJB will be used/invoked, making the other EJB not used at all. My concern there is that other wasted EJB instance.
I would appreciate any of your insights on these.
- Pat
