Interface EJBHome

All Superinterfaces:

Remote

All Known Subinterfaces:

ManagementHome

---

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 EJB objects, as well as home business methods that are not specific to a bean instance (Session Beans do not have finders and home methods).

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

---

Method Summary
EJBMetaData	getEJBMetaData()           Obtain the EJBMetaData interface for the enterprise Bean.
HomeHandle	getHomeHandle()           Obtain a handle for the remote home object.
void	remove(Handle handle)           Remove an EJB object identified by its handle.
void	remove(Object primaryKey)           Remove an EJB object identified by its primary key.

 

Method Detail

remove

void remove(Handle handle)
            throws RemoteException,
                   RemoveException

Remove an EJB object identified by its handle.

Throws:

RemoveException - Thrown if the enterprise Bean or the container does not allow the client to remove the object.

RemoteException - Thrown when the method failed due to a system-level failure.

---

remove

void remove(Object primaryKey)
            throws RemoteException,
                   RemoveException

Remove an EJB 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.

Throws:

RemoveException - Thrown if the enterprise Bean or the container does not allow the client to remove the object.

RemoteException - Thrown when the method failed due to a system-level failure.

---

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:
