Help: how to look up ejb3 deployed in ear using jndi

[zzuli]

Hi,everyone:
I'm trying to use jndi to look up ejb3 depoyed in ear-file. The structure of ear file is like: taas.ear\app.jar , the "app.jar" is where the ejbs are deployed.
If i write code:

jndiContext.lookup("ServiceProviderDaoImpl/local");

There will be exception:

javax.naming.NameNotFoundException: ServiceProviderDaoImpl not bound

However, if i deploy the ejbs directly in a app.jar which is not in a ear-file, then same same code will work fine.

I cannot figure out how to write the correct code to look up the ejbs.
I use jboss 5.0.1GA.
Could anyone help me? Thanks a lot.

When deployed in an ear, the default jndi name will be of the form:

EARName/BeanName/local

or

EARName/BeanName/remote

So in this case, you should use taas/ServiceProviderDaoImpl/local
