Hi!

I am migrating a project from JAS 6 Final to JAS 7.0.2 Final.

Here is the structure of my application:

EJB-MainEAR.ear
        JPA-Main.jar (JPA Project)
        EJB-MainClient.jar (EJB Interfaces Project)
        EJB-Main.jar (EJB Session Beans Project)
        GWT-Main.war (Web Project)

I read the article 
https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7 and i am 
aware of the property ear-subdeployments-isolated.

I tried to add this property to the file 
C:\jboss7\standalone\configuration\standalone.xml setting it to FALSE.
<subsystem xmlns="urn:jboss:domain:ee:1.0">
        <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
</subsystem>

But i get this error message whe starting JBoss. 
"SistemaSession" is the EJB interface inside EJB-MainClient.jar.

10:39:03,356 WARN  [org.jboss.modules] (MSC service thread 1-4) Failed to 
define class com.framework.business.ejb.session.SistemaSessionBean in

Loader: java.lang.LinkageError: Failed to link

"deployment.EJB-MainEAR.ear.EJB-Main.jar:main" from Service Module Loader)

Then i tried to add a jboss-deployment-structure.xml file to the EAR, 
defining all the dependencies.

<jboss-deployment-structure>
  <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
  <deployment>
    <dependencies>
      <module name="com.keyworks.k3" />
    </dependencies>
  </deployment>
  <sub-deployment name="JPA-Main.jar">
  </sub-deployment>
  <sub-deployment name="EJB-MainClient.jar">
    <dependencies>
      <module name="deployment.EJB-MainEAR.ear.JPA-Main.jar:main" />
    </dependencies>
  </sub-deployment>
  <sub-deployment name="EJB-Main.jar">
    <dependencies>
      <module name="deployment.EJB-MainEAR.ear.JPA-Main.jar:main" />
          <module 
name="deployment.EJB-MainEAR.ear.EJB-MainClient.jar:main" />
    </dependencies>
  </sub-deployment>
  <sub-deployment name="GWT-Main.war">
    <dependencies>
      <module name="deployment.EJB-MainEAR.ear.JPA-Main.jar:main" />
          <module 
name="deployment.EJB-MainEAR.ear.EJB-MainClient.jar:main" />
    </dependencies>
  </sub-deployment>
</jboss-deployment-structure>

And the error message when starting JBoss was:

What i need to do for my modules (JAR and WAR) to see each other and get 
this working?
