JBoss Enterprise Application Platform - Version 6.1.0.GA adding custom log handler - jboss

Question

I am trying to add a custom log handler to the JBoss Enterprise Application Platform - Version 6.1.0.GA using a tutorial. However, when I add my module to the joboss modules, and update the standalone.xml for the custom log handler and then starting jboss, it crashes.Below is the custom log module.xml and standalone.xml configuration. In the standalone.xml, my custom handler is configured under the custom handler tag.
module.xml
<module xmlns="urn:jboss:module:1.1" name="siteelf.loggers">
<resources>
<resource-root path="SiteElfCustomLogger.jar"/>
<!-- Insert resources here -->
</resources>
<dependencies>
<module name="org.jboss.logging"/>
<module name="javax.api"/>
</dependencies>
</module>
standalone.xml
