Does JBoss 7 support local EJB clients from different applications?

[tinche]

Hello.

The EJB 3.1 spec states:

Access to an enterprise bean through the local client view is only required to be supported for local clients packaged within the same application as the enterprise bean that provides the local client view.

Compliant implementations of this specification may optionally support access to the local client view

of an enterprise bean from a local client packaged in a different application. The configuration requirements for inter-application access to the local client view are vendor-specific and are outside the scope

of this specification. Applications relying on inter-application access to the local client view are

non-portable.

Does JBoss 7.1 support local EJB access from different applications, and if so, under which circumstances?

Thanks in advance.

I've not checked explicit, but I've used this in former versions. I see no reason why it should not supported.

You can call via local interface if you run the application in the same JVM (server instance)

Possibly because of the way JBoss isolates different deployments. I was hoping for an authoritative answer, since the documentation for this is currently missing. (https://docs.jboss.org/author/display/AS71/Enterprise+JavaBeans+Technology+%28EJB%29)

You should not be using local interfaces for that instead you should be using remote interfaces. Take a look at this Java EE documentation http://docs.oracle.com/javaee/6/tutorial/doc/gipjf.html#gipiz (the "Local Clients") section. Here's the relevant part:

Local Clients

A local client has these characteristics.

• It must run in the same application as the enterprise bean it accesses.

That's fine, we do use remote interfaces.

The spec (in the OP) states vendors are required to support remote access, but may support local access as well. I was curious whether JBoss supports it or not. Judging by your answer, I'm going to go with a definite 'no'.

Which is perfectly fine, but might be clearly stated in the documentation.

Just to updating the post, two years later(feb/2015) I make this test and the behavior is the same yet. JBoss does not support call of EJB using Local interfaces client from other application in the same container instance that is not the same package where EJB is contained.

I made a simple injection in a Servlet using @EJB and this runs only when I use @Remote interface

Curiously using Apache Camel with Spring, in a route using "ejb" component is possible to use @Local interface in a separate app to call EJB
