Java Enterprise Edition (EE)

EJBObject


javax.ejb
Interface EJBObject

All Superinterfaces:
java.rmi.Remote
All Known Subinterfaces:
Management
public interface EJBObject
extends java.rmi.Remote

The EJBObject interface is extended by all enterprise Beans' remote interfaces. An enterprise Bean's remote interface provides the remote client view of an EJB object. An enterprise Bean's remote interface defines the business methods callable by a remote client.

The remote interface must extend the javax.ejb.EJBObject interface, and define the enterprise Bean specific business methods.

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

Method Summary
 EJBHome getEJBHome()
          Obtain the enterprise Bean's remote home interface.
 Handle getHandle()
          Obtain a handle for the EJB object.
 java.lang.Object getPrimaryKey()
          Obtain the primary key of the EJB object.
 boolean isIdentical(EJBObject obj)
          Test if a given EJB object is identical to the invoked EJB object.
 void remove()
          Remove the EJB object.
 

Method Detail

getEJBHome

EJBHome getEJBHome()
                   throws java.rmi.RemoteException
Obtain the enterprise Bean's remote home interface. The remote home interface defines the enterprise Bean's create, finder, remove, and home business methods.

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

getPrimaryKey

java.lang.Object getPrimaryKey()
                               throws java.rmi.RemoteException
Obtain the primary key of the EJB object.

This method can be called on an entity bean. An attempt to invoke this method on a session bean will result in RemoteException.

Returns:
The EJB object's primary key.
Throws:
RemoteException - Thrown when the method failed due to a system-level failure or when invoked on a session bean.

remove

void remove()
            throws java.rmi.RemoteException,
                   RemoveException
Remove the EJB object.

Throws:
RemoteException - Thrown when the method failed due to a system-level failure.
RemoveException - The enterprise Bean or the container does not allow destruction of the object.

getHandle

Handle getHandle()
                 throws java.rmi.RemoteException
Obtain a handle for the EJB object. The handle can be used at later time to re-obtain a reference to the EJB object, possibly in a different Java Virtual Machine.

Returns:
A handle for the EJB object.
Throws:
RemoteException - Thrown when the method failed due to a system-level failure.

isIdentical

boolean isIdentical(EJBObject obj)
                    throws java.rmi.RemoteException
Test if a given EJB object is identical to the invoked EJB object.

Parameters:
obj - An object to test for identity with the invoked object.
Returns:
True if the given EJB object is identical to the invoked object, false otherwise.
Throws:
RemoteException - Thrown when the method failed due to a system-level failure.
