I am trying to migrate my application ( EAR) from jboss 7.1 to wildfly . So to achieve this i copied over the configuration from standalone-full.xml from 7.1 to wildfly (8.0) ( datasources , queues etc ) . The app is not able to connect to any of the datasources defined . The same conf works on 7.1 but not on wildfly (8.0 ) . I see this error a lot on the console .
