JBoss eap6 runtime Empty in eclipse

Hi,

I have migrated to JBoss EAP 6 in Eclipse Juno. I am not using maven. I have intalled befor the JBoss tools JUNO (version 4.0).
I have specified JBoss EAP 6 runtime in my Java Build Path, but it was EMPTY !!.
So my question is why is it empty and how to fix this ?
