Calling a remote ejb on a different glassfish 4.0 instance

Question

I have two servers installed. Both are running an own Glassfish 4.0 domain.

On one server, I've installed an Singleton Remote EJB. This Glassfish has an IIOP-Listener specified (name=UF enabled=true network adress=192.168.10.95 listener port=1072).

The second Glassfish instance is running a simple JSF-2.2 Application. Now I'm trying to connect to the remote ejb in one JSF-Managed-Bean constructor.

        Properties props = new Properties();
        props.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.enterprise.naming.SerialInitContextFactory");
        props.put(Context.PROVIDER_URL, "iiop://192.168.10.95:1072");
        props.setProperty("org.omg.CORBA.ORBInitialHost", "192.168.10.95");
        props.setProperty("org.omg.CORBA.ORBInitialPort", "1072");
        InitialContext ctx = new InitialContext(props);
        return (IUF) ctx.lookup("java:global/UFRemote/UFRemote!com.uf.IUF");

The lookup took about one minute and ends up with following exception:

I think, something is wrong with the connection, because everything works fine, if I deploy both on the same Glassfish instance.

How do I call a remote EJB correctly from a different Glassfish domain?

Answer 1

1) IP Addressing

Try to set org.omg.CORBA.ORBInitialHost to the network host-name instead the ip address. Make sure that the client can reach the server by host-name (ping host-name), if necessary edit hosts table (linux: etc/hosts windows: c:\windows\system32\drivers\hosts) and add a line with:

'ip' 'host-name' (Example 192.168.1.1 server1)

(Even after you solve the naming issue, problems can appear because of direct ip addressing )

2) Accessing EJB Components in a Remote GlassFish Server

In addition to the ip issue, make sure that the server as declared the JDNI resource. See text bellow from Glassfish Application-development-guide Manual:

The recommended approach for looking up an EJB component in a remote GlassFish Server from a client that is a servlet or EJB component is to use the Interoperable Naming Service syntax. Host and port information is prepended to any global JNDI names and is automatically resolved during the lookup. The syntax for an interoperable global name is as follows:

corbaname:iiop:host:port#a/b/name

This makes the programming model for accessing EJB components in another GlassFish Server exactly the same as accessing them in the same server. The deployer can change the way the EJB components are physically distributed without having to change the code.

For Java EE components, the code still performs a java:comp/env lookup on an EJB reference. The only difference is that the deployer maps the ejb-ref element to an interoperable name in a GlassFish Server deployment descriptor file instead of to a simple global JNDI name.

For example, suppose a servlet looks up an EJB reference using java:comp/env/ejb/Foo, and the target EJB component has a global JNDI name of a/b/Foo.

The ejb-ref element in glassfish-web.xml looks like this:

<ejb-ref>
    <ejb-ref-name>ejb/Foo</ejb-ref-name>
    <jndi-name>corbaname:iiop:host:port#a/b/Foo</jndi-name>
</ejb-ref>

The code looks like this:

Context ic = new InitialContext();
Object o = ic.lookup("java:comp/env/ejb/Foo");

For a client that doesn't run within a Java EE container, the code just uses the interoperable global name instead of the simple global JNDI name. For example:

Context ic = new InitialContext();
Object o = ic.lookup("corbaname:iiop:host:port#a/b/Foo");

Objects stored in the interoperable naming context and component-specific (java:comp/env) naming contexts are transient. On each server startup or application reloading, all relevant objects are re-bound to the namespace.
