Class EJBMetaDataImpl

java.lang.Object
  org.openejb.client.EJBMetaDataImpl

All Implemented Interfaces:

Externalizable, Serializable, javax.ejb.EJBMetaData

public class EJBMetaDataImpl
extends Object
implements javax.ejb.EJBMetaData, Externalizable

------------------------------------------------- EJB 1.1 9.3.6 Meta-data class The deployment tools are responsible for implementing the class that provides meta-data information to the client view contract. The class must be a valid RMI-IIOP Value Type, and must implement the javax.ejb.EJBMetaData interface. Because the meta-data class is not entity bean specific, the container may, but is not required to, use a single class for all deployed enterprise beans. ------------------------------------------------- The OpenEJB implementation of the javax.ejb.EJBMetaData interface.
