JBoss CMP 2.0 does not need a mapping. By default, it will create all db tables. The default datasource used is defined in jboss-3.0.x/server/default/conf/standardjbosscmp-jdbc.xml

JBoss ships with HypersonicSQL. This is an embedded Java relational DB and the default datasource (java:/DefaultDS)

exactly.

yes, it will be your job to map the JBoss CMP stuff over your legacy schema. Sometimes, tricky mappings are not possible and may be a problem for your project. JBoss 4.0 will allow for much more flexible mappings though.

The 7.2 example/deployment seems to be missing the mapping for the ShipEJB to the Ship table and ALL relationship mappings in the jbosscmp-jdbc.xm file. Am I missing something?
