Jars in the JBoss EAP 6 Runtime

I have downloaded JBoss developer Studio, by adding the JBoss EAP 6 runtime, I have seen that it contains only some jars but not all of them. So I have errors in some jar import in my code (exp : ironjacamar-jdbc-jar which is in the folder C:\jboss-eap-6.1\modules\system\layers\base\org\jboss\ironjacamar\jdbcadapters\main).

What are these jars that JBoss eap 6 runtimes contains by default?
How to fix the missing jars that comes with JBoss eap 6 but are not seen in the Java Build Path?

PS: I don't like to use maven.
