Remote EJB Lookup via JNDI on Jboss EAP 6.4

I'm trying to run the ejb-remote example from here: Jboss eap quickstart

I don't see any issues when I run the server and client on the same machine. However there are issues if the client is executed from a different machine than on server.

I'm assuming the examples provided by jboss team should be working out of the box. I also read article on https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI and various online blogs. Please let me know if I am missing anything obvious. Trying to get the remote client working for couple of days now. :(

ENV: Server deployed on Jboss EAP 6.4. JDK/JAVA version 8.

Few issues caused the problem.

  1. Port should be 4447, the one in the project on jboss is 8080.

  2. one should add user via JBOSS_HOME/bin/add-user.sh and add it to the jboss-ejb-client.properties as below.

    remote.connection.default.username=user2 remote.connection.default.password=password12(

  3. Use the correct version of client. In my case I was using 6.4 version of server and 7.0.X version of client.
