Class Loading and Modules
here is my deployment outline for AS7:
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
