Not able to deploy EAR file

Question

I am developing a web module in struts2 framework and ejb module in eclipse with hibernate as ORM framework. Every time when I modify my ejb module I have to package it into jar and include it in my web module /WEB-INF/lib folder in order to run my whole application. Though the application worked fine in this way but it was really time consuming. So I tried to map them in a EAR module. But when I try to run EAR module. It gives below exceptions

2016-12-24 13:23:43,992 ERROR [org.apache.struts2.dispatcher.DefaultDispatcherErrorHandler] (default task-4) Exception occurred during processing request: WFLYEJB0442: Unexpected Error: javax.ejb.EJBException: WFLYEJB0442: Unexpected Error

Below is where I suspect to get the exception

private static SessionFactory sessfct = SessionFactoryGenerator.getSessionFactory();

It seems to be some issue with classloader. Since earlier it use to work fine with same set of jars when EAR was not in the picture. I am probably new to EAR. Below is the structure of application.xml

  <module>
    <web>
      <web-uri>EBS-web.war</web-uri>
      <context-root>EBS-web</context-root>
    </web>
  </module>
  <module>
    <ejb>EBS-ejb.jar</ejb>
  </module>

I also tried including all the jars in EAR lib folder but no success was achieved

You can not deploy your EAR file because the following class could not be found.

java.lang.ClassNotFoundException: org.hibernate.HibernateException

Make sure you have hibernate libraries in your server lib folder or packed in your EAR lib archive.
