What engine does OpenEJB use for CMP?
In versions 1.0 and before, OpenEJB uses Castor JDO for CMP persistence. The CMP config files are all Castor controlled files (http://www.castor.org). At the moment, most of the real juicy CMP configuration file information is at the Castor site. There is no difference between configuring a CMP EntityBean in OpenEJB than with any other Castor controlled java object, so anything you learn about Castor’s config files will be applicable.
