java.lang.Object org.ow2.jonas.lib.ejb21.JContext org.ow2.jonas.lib.ejb21.JEntityContext
public class JEntityContext
This class implements javax.ejb.EntityContext interface. An Entitycontext is bound to a bean instance. To be used, it must be associated to a JEntitySwitch, and possibly to a Transaction. In case the Context is used inside a Transaction, we use the Synchronization interface to be aware of transaction demarcations.
