All known Subclasses: java.rmi.activation.ActivationGroup,
| UnicastRemoteObject | | public class UnicastRemoteObject extends RemoteServer (Code) | | Used for exporting a remote object with JRMP and obtaining a stub
that communicates to the remote object.
For the constructors and static exportObject methods
below, the stub for a remote object being exported is obtained as
follows:
- If the remote object is exported using the
UnicastRemoteObject.exportObject(Remote) UnicastRemoteObject.exportObject(Remote) method,
a stub class (typically pregenerated from the remote object's class
using the
rmic tool) is loaded and an instance of that stub
class is constructed as follows.
- A "root class" is determined as follows: if the remote object's
class directly implements an interface that extends
Remote , then
the remote object's class is the root class; otherwise, the root class is
the most derived superclass of the remote object's class that directly
implements an interface that extends
Remote.
- The name of the stub class to load is determined by concatenating
the binary name of the root class with the suffix
"_Stub".
- The stub class is loaded by name using the class loader of the root
class. The stub class must extend
RemoteStub and must have a
public constructor that has one parameter, of type
RemoteRef .
- Finally, an instance of the stub class is constructed with a
RemoteRef .
- If the appropriate stub class could not be found, or the stub class
could not be loaded, or a problem occurs creating the stub instance, a
StubNotFoundException is thrown.
- For all other means of exporting:
- If the remote object's stub class (as defined above) could not be
loaded or the system property
java.rmi.server.ignoreStubClasses is set to
"true" (case insensitive), a
java.lang.reflect.Proxy instance is constructed with the following
properties:
- The proxy's class is defined by the class loader of the remote
object's class.
- The proxy implements all the remote interfaces implemented by the
remote object's class.
- The proxy's invocation handler is a
RemoteObjectInvocationHandler instance constructed with a
RemoteRef .
- If the proxy could not be created, a
StubNotFoundException will be thrown.
- Otherwise, an instance of the remote object's stub class (as
described above) is used as the stub.

| exportObject | | public static Remote exportObject(Remote obj, int port, RMIClientSocketFactory csf, RMIServerSocketFactory ssf) throws RemoteException(Code) | | Exports the remote object to make it available to receive incoming
calls, using a transport specified by the given socket factory.
Parameters:
obj - the remote object to be exported
Parameters:
port - the port to export the object on

| unexportObject | | public static boolean unexportObject(Remote obj, boolean force) throws java.rmi.NoSuchObjectException(Code) | | Removes the remote object, obj, from the RMI runtime. If
successful, the object can no longer accept incoming RMI calls.
If the force parameter is true, the object is forcibly unexported
even if there are pending calls to the remote object or the
remote object still has calls in progress. If the force
parameter is false, the object is only unexported if there are
no pending or in progress calls to the object.
Parameters:
obj - the remote object to be unexported
Parameters:
force - if true, unexports the object even if there arepending or in-progress calls; if false, only unexports the objectif there are no pending or in-progress calls true if operation is successful, false otherwise
exception:
NoSuchObjectException - if the remote object is notcurrently exported
