JBoss EAP 6.1 module.xml dependency for Core Java jars

I have created a module.xml configuration file and added some jars which has dependency on Core Java jars. Shall I copy all the relevant Java jars and create a separate module and take that module as a dependency ? Is it the right way ? Below is what I get when I execute my web app

Caused by: java.lang.ClassNotFoundException: javax.security.auth.callback.CallbackHandler from [Module "com.granite.shared:main" from local module loader @11560a9 (finder: local module finder @7d3660 (roots: C:\Program Files (x86)\Jboss\jboss-eap-6.1\modules,C:\Program Files (x86)\Jboss\jboss-eap-6.1\modules\system\layers\base))]

P.S :- I have seen the default modulus already present in JBoss 6.1 but didn't found the right package for CallbackHandler

Thanks in Advance !
