jars will be deployer before the datasource(-ds.xml), so if there are some classes that are getting initialized and require the datasource it will fail because the -ds.xml are not deployed untill the .jar's are deployed. You should look for the strict deployment as explained over here https://jira.jboss.org/jira/browse/JBAS-2904
Also make sure that the jboss jca MBeans are getting created after the server booting is over, you should look at the jboss.jca:* MBeans through the jmx-console. You should be able to see the set of Mbeans related to the the configured datasource, I don't see any issue with the data source files.
