EJB, removal between two application servers (glass fish)


I want to have a bean Fooin the host A, which is entered using the annotation @EJBfor the bean Barin the host B.
Both of these nodes are separate standalone instances Glassfish-v3.
When reading the documents, GlassfishI found a lot of information, some of them sounded a bit contradictory.
I realized that every bean has a global jndi assigned to it and understands how it is built. What is the syntax for portable JNDI global names? . I also realized that the declaration Fooin Barshould be something like this (assuming it FooRemoteis a remote business interface Fooand fooejbis its module):, @EJB(lookup=java:global/fooejb/FooRemote) FooRemote foothis is based on this .
I can't figure out where I say host Aand host Bto get to know each other.
I saw many examples for application clients and application servers, but I could not find an example for such a scenario.
In this issue Set sun-web.xmland Global-JNDI, but I think it's not EJB3.1 (since it is not Portable JNDI), and I do not understand where it should be this sun-web.xml(I'd like to avoid it if you can).
This mainly differs in two ways:

  • There is no option -Dorg.omg.CORBA.ORBInitialHost = param (as far as I can see)
  • Any solution should, of course, allow the inclusion of a third host C, with which they interact both Afor and Bfor different purposes.

We use remote EJBs and work great.

First, you'll need an EJB on "Host A", which implements an interface whose class is present on both hosts.

//For host A + B
public interface FooClass {
    public void theMethod();
}

//Only for host A
@Stateless
public class FooClassImpl implements FooClass {
    public void theMethod(){//Code goes here}
}

Then you need to create (on host B) the glassfish-web.xml file in your WEB-INF directory, where you specify where the remote EJB is located:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">
<glassfish-web-app error-url="">
  <ejb-ref>
    <ejb-ref-name>RemoteEJBName</ejb-ref-name>
    <jndi-name>corbaname:iiop:<servername or IP>:3700#java:global/<projectname>/FooClassImpl!com.test.foo.FooClass</jndi-name>
  </ejb-ref>
</glassfish-web-app>

At the injection point on host B, you need to enter EJB as follows:

@EJB(name = "RemoteEJBName")
private FooClass theFooClassInstance;

Hope this helps.
