Now, I don't know , how to connect/lookup between EJB in one JVM and EJB in another JVM ...


help me please ...

EJB in machine A can use JNDI to lookup the remote component or home interface for the EJB in machine B, creating it (if necessary), and then use the EJBObject to get the services from EJB in machine B.

Properties properties = new Properties(); 
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "allaire.ejipt.ContextFactory");
properties.setProperty(Context.PROVIDER_URL, "ejipt://localhost:2323");
Context ctx = new InitialContext(properties);
*/
 
  

Value for Context.INITIAL_CONTEXT_FACTORY depends on the app server. Context.PROVIDER_URL is the server URL.

Of course, EJB in machine B must register its services and JNDI name to the JNDI registry. Or, there maybe a Service Locator that knows which locations that the EJB located.

What do you mean connect between EJB in one machine and EJB in other machine?
Is it about a cluster? Or is it only 2 applications communication?
If the 1st is true: you declare ejb-ref and than you perform the normal lookup (and is not important where exactly the container is running)
If 2nd is true: your EJB wanting connection will need to do the same steps as a regular client.

If 2nd is true: your EJB wanting connection will need to do the same steps as a regular client

yes, but dont forget to pass the URL of the 2nd machice to the InitialContext.
