org.jboss.as.cmp.jdbc.bridge.JDBCCMRFieldBridge
JDBCCMRFieldBridge a bean relationship. This class only supports relationships between entities managed by a JDBCStoreManager in the same application.
Life-cycle: Tied to the EntityBridge.
Multiplicity: One for each role that entity has. @author Dain Sundstrom @author Alex Loubyansky @version $Revision: 81030 $
