Here's my question:
I have some Stateless Session Bean classes. This is a very simple applications
which lets users leave their names and phone numbers so a salesman can contact
them later. To do this, I have set up an Inquiry entity bean.
I also have a stateless session bean called InquiryManagerBean. There is an
InquiryManagerBean interface like this:
| @Local public interface InquiryManagerBean {
|
| /** Create a new persistent Inquiry instance */
| public Inquiry create(Inquiry toCreate);
| }
|
And then a class which implements it:
| @Stateless public class InquiryManagerBeanLocal implements
InquiryManagerBean {
|
| @PersistenceContext EntityManager entityManager;
|
| /** Creates a new instance of InquiryManagerBeanLocal */
| public InquiryManagerBeanLocal() {
| }
|
| public Inquiry create(Inquiry toCreate) {
| if(entityManager == null) {
| logger.severe("No entity manager was found in " +
| "this persistence context! Nothing will work.");
| return null;
| }
| if(toCreate == null) return null;
| entityManager.persist(toCreate);
| return toCreate;
| }
|
| }
|
Now I have a servlet that needs to get this InquiryManagerBean so it can
persist inquiries, etc. It looks it up like this:
| InitalContext context = new InitialContext();
| InquiryManagerBean inquiryManagerBean =
| (InquiryManagerBean)
context.lookup("MyApplicationName/InquiryManagerBeanLocal/local");
|
My question is, this does not make sense. Shouldn't I be looking the bean up
as "MyApplicationName/InquiryManagerBean/local"? The servlet is getting an
interface which is not necessarily an instance of the actual
InquiryManagerBeanLocal class. All it knows about or cares about is that the
object it gets implements InquiryManagerBean.
So, am I doing something wrong, or?
Thanks
