I could not deploy an ear but I can rename my ear as a .SAR under the following conditions
The packages are in a jar file and located in the [SAR]/lib directory
The jboss-service.xml will not get picked up by the class loader unless it is in the [SAR]/META-INF directory.
It should look like this
I set this up in eclipse and export as an ear, then rename it to SAR. Hope this helps.
