javax.ejb Interface EJBHome
- 所有父接口:
- Remote
- 所有已知子接口:
- 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.
| 方法摘要 | |
|---|---|
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. |
| 方法详细信息 |
|---|
remove
void remove(Handle handle) throws RemoteException, RemoveException
- Remove an EJB object identified by its handle.
- 抛出异常:
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.
- 抛出异常:
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.
- 返回:
- The enterprise Bean's EJBMetaData interface.
- 抛出异常:
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.
- 返回:
- A handle for the remote home object.
- 抛出异常:
RemoteException- Thrown when the method failed due to a system-level failure.
