I don't think you can do that. The Local interface is only accessible
inside the same application (which is your .ear). To access it from
another application, even running on the same GlassFish instance, you
will have to use a Remote interface (or some other approach, for
example, a coarse-grained JAX-RS (REST) web service).

How can I call a Local Session Bean inside an EAR from another EAR, both
deployed in the same Glassfish v3 domain?
This is the structure:
Glassfish v3 Domain1
EAR1
EAR1-EJB.jar
class TestSessionBean <-- @Stateless
common.jar
interface TestSessionLocal <-- @Local
EAR2
EAR2-EJB.jar
class TestSessionBeanClient <-- @Singleton, @LocalBean
common.jar
interface TestSessionLocal <-- @Local
TestSessionBean implements TestSessionLocal, boths EARs has common.jar.
I need to use TestSessionBean from TestSessionBeanClient. I would like to take
advantage of local session bean because of performance.
I know I can't use a simple @EJB call in the TestSessionBeanClient, so I tried
to lookup like this:
InitialContext ic = new InitialContext();
TestSessionLocal tsl = ic.lookup("java:global/EAR1/EAR1-
EJB/TestSessionBean!org.test.TestSessionLocal");
That will throw a ClassCastException because the returned object will not be
TestSessionLocal but a proxy class like:
TestSessionLocal_1389930137
that to be able to call its methos I must do reflection to find its methods.
Please help.
Thank you in advance.

| I completely agree, I wish there was a specification-compliant way to get around using a remote interface for this very situation. |

Local EJB access across applications is not supported in GlassFish.

The EJB spec does not disallow invocation of local EJBs from other applications. It is an optional feature and left to vendors. In GlassFish, one can access local EJBs from other applications by using OSGi/EJB applications approach, where in the local EJBs are made available as OSGi services and then consumed from other bundles using OSGi service registry.

I believe Jason iis correct, as according to the EJB specification, you must use the remote interface to access and EJB from another archive (EAR, EJB, or WAR). This is for security reasons, because you may have both a local and remote interface on a single EJB class, allowing you to specify different interfaces for internal and external consumption. I'm curious as to why the JNDI approach works - and wonder if this is actually a bug. There are several cases I would not like to expose my internal business interface out to the world, but if it was simply available through JNDI from another EAR running on the same domain. I think you might have found a bug =)
Which version of GF are you running (3.0.1, 3.1)? I'm interested in testing this, as it has security implications for me.
Thanks,
