Not able to deploy EAR file

问题

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

回答1:

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.
