             Summary: Class Loading and Modules
                 Key: AS7-5673
                 URL: https://issues.jboss.org/browse/AS7-5673
             Project: Application Server 7
          Issue Type: Clarification
          Components: EJB
    Affects Versions: 7.1.1.Final
            Reporter: Bill Rosenberg
            Assignee: jaikiran pai
            Priority: Minor
             Fix For: No Release



here is my deployment outline:

JB7.ear
--jboss-deployment-structure.xml
--JB7EJB.jar
--JB7Web.war
--JB7Dao.jar


I have a question regarding AS7 module class loading. I am trying to use the quartz library and setup a module to 
do so. I updated the jboss-deployment-structure.xml to look like this after setting up my quartz module

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">
	<ear-subdeployments-isolated>true</ear-subdeployments-isolated>
	<deployment>
		<dependencies>
		 	
			<module name="org.hibernate" slot="3" />
		 	<module name="org.quartz" />
			 
        </dependencies>
	</deployment>

</jboss-deployment-structure>

when i deploy and run the app a getthis exception:

When i change the  jboss-deployment-structure.xml to look like this, it runs fine:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">
	<ear-subdeployments-isolated>true</ear-subdeployments-isolated>
	<deployment>
		<dependencies>
		 	
			 <module name="org.hibernate" slot="3" />
			
			 
        </dependencies>
	</deployment>
	<sub-deployment name="JB7EJB.jar">
		<dependencies>
		 	
			<module name="org.quartz" /> 
			
		</dependencies>
	</sub-deployment>
</jboss-deployment-structure>


I thought that if i put the dependencies under the top 'deployment' section, that all deployments will pick up the quartz module, but i have to add the
  '<sub-deployment name="JB7EJB.jar">' section to have the JB7EJB deloyment pick up the quartz module.

 What am i missing here?
 
 thank you,
 
 Bill
