Portable JNDI Syntax lookup for EJB on Glassfish

问题:

Previous attempts were to have Netbeans deploy an EJB module, which builds as a JAR rather than an EAR, onto the Glassfish server which Netbeans has access to. However, deploying that JAR to Glassfish through the CLI with asadmin possibly runs into a bug.

The EAR deploys through the CLI without issue -- however, the JNDI names for the EJB doesn't appear to work. What is the discrepancy?

32.4.1.1 Portable JNDI Syntax

Three JNDI namespaces are used for portable JNDI lookups: java:global, java:module, and java:app.

The java:global JNDI namespace is the portable way of finding remote enterprise beans using JNDI lookups. JNDI addresses are of the following form: java:global[/application name]/module name /enterprise bean name[/interface name ] Application name and module name default to the name of the application and module minus the file extension. Application names are required only if the application is packaged within an EAR. The interface name is required only if the enterprise bean implements more than one business interface.

http://docs.oracle.com/javaee/7/tutorial/doc/ejb-intro004.htm

What is the correct syntax to lookup this bean? Is it java:global/HelloEAR/HelloEAR-ejb/greetings.GreetingsBeanRemote? I've tried more than a few variants of that without success.

deploying the app:

thufir@dur:~$ 
thufir@dur:~$ glassfish-4.1/glassfish/bin/asadmin list-applications
HelloEAR  <ear, ejb>  
Command list-applications executed successfully.
thufir@dur:~$

Why is the invocation of the bean without "java:" or anything like that?

If you are using Maven as well then check if "-1.0-SNAPSHOT" (or other version/as per your app) is attached at the end of the application-ejb file name as "application-ejb-1.0-SNAPSHOT", The full name would be "java:global/application-ear/application-ejb-1.0-SNAPSHOT/fileName"
