Root Cause

Bug in JBOSS prevented the Global Module for oracle from being generated.


Perform the following local-change:

Make the Oracle JDBC driver a global module.

Add lines similar the following to the domain subsystem element. The remote library name depends on the version of Red Hat JBoss app server.

This example is correct for Red Hat JBoss 6.x and above:

<module name=""/>
<module name="org.jboss.remoting-jmx" slot="main"/>
