I checked the web console and I was able to confirm that, in fact, Jboss is starting my data source properly. That said, it appears that my application cannot find it.
I have tried various combinations of jndi names on both sides : java:xxx_prod_ds and just xxx_prod_ds but nothing seems to work. Any suggestions?
Keep in mind that I've got the proper jndi names configured in my 4.2 instance and just copied those files over.
