Just a shot in the dark, but do I need a local interface to call a remote stateless EJB?
when I try call the bean remotely through Netbeans:
Netbeans doesn't allow a remote call, or any call, on this bean. Why not?
Trying to do it manually, as below:
What is the jndi global remote name for the Remote EJB which is deployed on glassfish?
INFO: visiting unvisited references
INFO: visiting unvisited references
INFO: EJB5181:Portable JNDI names for EJB MyRemoteSessionClass: [java:global/RemoteSalutation-ejb/MyRemoteSessionClass!net.bounceme.dur.glassfish.MyRemoteSession, java:global/RemoteSalutation-ejb/MyRemoteSessionClass]
INFO: RemoteSalutation-ejb was successfully deployed in 941 milliseconds.
If possible, I would rather specify the class in the properties file rather than hard-coded. In any event, different variations result in a lookup failure. Here's the stack-trace:

the remote EJB:
package net.bounceme.dur.glassfish;
import javax.ejb.Stateless;
//@LocalBean
@Stateless(mappedName = "salutationBean")
public class MyRemoteSessionClass implements MyRemoteSession {
@Override
public String SayHello() {
return "hello from glassfish..";
}
@Override
public String SayBye() {
return "goodbye..";
}
}
note that the interface is remote, ie: it's literally a Java class library. Correct? This makes the EJB remote.
referencing:
https://netbeans.org/kb/docs/javaee/entappclient.html
although I changed the names a bit..otherwise should be exactly as the tutorial.
Try Object o = ic.lookup("salutationBean");
Note that mappedName specifies the name to use in JNDI for a remote access.
