Interface EJBHome

All Superinterfaces:
Remote
public interface EJBHome extends Remote
The EJBHome interface must be extended by all enterprise beans' remote home interfaces. An enterprise bean's remote home interface defines the methods that allow a remote client to create, find, and remove enterprise bean objects.

The remote home interface is defined by the enterprise bean provider and implemented by the enterprise bean container.

Enterprise beans written to the EJB 3.0 and later APIs do not require a home interface.

Since:
EJB 1.0

    • remove

      void remove(Object primaryKey) throws RemoteException, RemoveException
      Remove an enterprise bean object identified by its primary key.

      This method can be used only for an entity bean. An attempt to call this method on a session bean will result in a RemoveException.

      Note: Support for entity beans is optional as of EJB 3.2.

      Parameters:
      primaryKey - the primary key of the enterprise bean object to be removed
      Throws:

    • getEJBMetaData

      EJBMetaData getEJBMetaData() throws RemoteException
      Obtain the EJBMetaData interface for the enterprise bean. The EJBMetaData interface allows the client to obtain information about the enterprise bean.

      The information obtainable via the EJBMetaData interface is intended to be used by tools.

      Returns:
      The enterprise Bean's EJBMetaData interface.
      Throws:
      RemoteException - Thrown when the method failed due to a system-level failure.

    • getHomeHandle

      HomeHandle getHomeHandle() throws RemoteException
      Obtain a handle for the remote home object. The handle can be used at later time to re-obtain a reference to the remote home object, possibly in a different Java Virtual Machine.
      Returns:
      A handle for the remote home object.
      Throws:
      RemoteException - Thrown when the method failed due to a system-level failure.
