EJB 3.0 local interface JNDI

Question

Hello
I found some information that will probably help a lot of people having trouble with local interface not referenced in JNDI.
You need to delacre each local interface in the web.xml.
     <ejb-local-ref>
          <ejb-ref-name>MappedNameInYourEJB</ejb-ref-name>
          <ejb-ref-type>Session</ejb-ref-type>
<local> yourLocalInterface
          </local>
     </ejb-local-ref>
The weird thing about this is you don't need to do it when you use remote interface!! I would have thought Weblogic was smart enough to put your EJB in the JNDI when you declare @local on your interface!!
Am I wrong with something here?
When I read the EJB spec, it says you don't need to declare your EJB anywhere when you use annotation....
If someone have an explanation I would be very happy to read about it!!!!

Hi,
In our current impl, we don't bind local business interface impl onto global jndi, this is because adding global JNDI binding for local EJB means every local business interface object must be bound into global JNDI, which will give rise to strange errors when accessing remotely or in different application context.
On the other hand, you needn't add each local interface in the web.xml, you can use annotation through EJB link, which is the suggested way to use EJB local reference, for example:
@Stateful(name="AccountManagementBean")
public class AccountManagementBean
@EJB(
name="PersonBeanRef",
beanName="PersonBean"
Person person;
@Stateless(name="PersonBean")
public class PersonBean implements Person {
In this example, AccountManagementBean has a local reference of PersonBean, the key is you should use beanName in @EJB, whose value is the ejb name of referenced EJB.
