Class PersistenceBrokerBean

java.lang.Object
  org.apache.ojb.broker.core.PersistenceBrokerBean

All Implemented Interfaces:

java.io.Serializable, javax.ejb.EnterpriseBean, javax.ejb.SessionBean, PersistenceBroker, org.apache.ojb.broker.util.configuration.Configurable, ObjectContainer

public class PersistenceBrokerBean
extends java.lang.Object
implements PersistenceBroker, javax.ejb.SessionBean

Author:

Matthew Baird The PersistenceBrokerBean wraps a persistenceBroker implementation and allows PersistenceBroker server operations with communication happening over RMI. Useful if you are going to use OJB in a J2EE environment. Allows for OJB objects with proxies to be taken outside of the VM, say to an instance of a servlet container, and the proxies will call back on the bean to materialize proxies via standard RMI bean calls, instead of the custom protocol. Container will be responsible for pooling of bean instances. Can be used by normal EJB clients, not just the PersistenceBrokerClient

Description copied from interface: PersistenceBroker

Stores the given m:n implementor int the underlying persistence system. This is usually done by inserting a row in an indirection table.
Note that OJB currently doesn't handle collection inheritance, so collections descriptors are written per class. We try to match one of these collection descriptors, iterating from the left side and looking for possible for classes on the right side using isAssignableFrom(rightClass).
