EXP 5: Connect remote EJBs on clustered environment

Problem
Cannot connect remote EJBs on clustered enviroment (Glassfish 4 app server)

Cause
in clustered environment, Glassfish use different JNDI compare single server.

Solution
Correct JNDI as described as below:

java:globbal/<earname>/<ejbprojectname>/

You can find exactly JNDI on server.log file of Glassfish Server when it startup.

Example

java:global/gbear/gbeejb/

If EJB which you need to connect named TestEJB, the full JNDI is:

java:global/gbear/gbeejb/TestEJB

Quotes from server.log
