Your slave server log is empty. Do you have a firewall between this machines?
1. Please find attached slave logs.
2. We dont have any firewall inbetween its an open network.
Your logs don't match. One is from 11. feb the other is from 14. feb.
Try this example if it works for you: jboss-eap-quickstarts/MainAppSContextBean.java at 6.4.x-develop · jboss-developer/jboss-eap-quickstarts · GitHub
Set up a scoped ejb connection manually instead configuring it inside standalone.xml. I have more or less the same situation as you do and I've done it on AS7 using manual scoped connection (as described in the upper example) and it works correctly.

Hope it helps.
