I tried to use the usertype-mappings (standard)jbosscmp-jdbc.xml for ejb3 entity-beans. But I can not see any effect of my definitions on the generated tables and didn't get error messages when starting Jboss.
So my suspision is, that this definition have no relation to any EJB3-Stuff.
Am I right ? And If yes, is there another way to define some user mappings ?
