Uses of Class java. Packages that use RemoteException. Provides a class and two interfaces for the RMI registry. Provides classes and interfaces for supporting the server side of RMI.
Subclasses of RemoteException in java. Modifier and Type. An AccessException is thrown by certain methods of the java. Naming class specifically bind , rebind , and unbind to indicate that the caller does not have permission to perform the action requested by the method call. A ConnectException is thrown if a connection is refused to the remote host for a remote method call.
A MarshalException is thrown if a java. IOException occurs while marshalling the remote call header, arguments or return value for a remote method call.
A NoSuchObjectException is thrown if an attempt is made to invoke a method on an object that no longer exists in the remote virtual machine. A ServerError is thrown as a result of a remote method invocation when an Error is thrown while processing the invocation on the server, either while unmarshalling the arguments, executing the remote method itself, or marshalling the return value.
It's parameters are: local listening port used by the registry stub to receive one-to-one messages , registry multicast address and registry multicast port registry "frequency". Registry is the object that has to be started before exporting any remote object similar to RMI. The method LocateMcastRegistry. It has the same parameters as the method getRegistry. Registry can be started within the same process the remote object is exported:.
Way of use try-catch clause in example above assures that even when another process already created multicast registry on a given "frequency" and it's impossible to create own registry, there is still possibility to join already created one.
Registry in the MRMI library is jr. There is no way to use ordinary RMI registry - java. Registry class. Use of the replicated remote object is possible after obtaining a stub from the proper registry. It can be done with MutlticastRegistry. It's only parameter is the name of the object in the registry. Register an object descriptor for an activatable remote object so that is can be activated on demand. The registerObject method is used to register an activation descriptor, desc , and obtain an activation identifier for a activatable remote object.
Set the activation descriptor, desc for the object with the activation identifier, id. Set the activation group descriptor, desc for the object with the activation group identifier, id. Revokes previous registration for the activation descriptor associated with id. Remove the activation id and associated descriptor previously registered with the ActivationSystem ; the object can no longer be activated via the object's activation id. Constructs an activatable remote object by registering an activation descriptor with the specified location, data, and restart mode for this object, and exporting the object with the specified port.
Constructs an activatable remote object by registering an activation descriptor with the specified location, data, and restart mode for this object, and exporting the object with the specified port, and specified client and server socket factories. The clean call removes the 'vmid' from the reference list of each remote object indicated in 'id's.
The dirty call requests leases for the remote object references associated with the object identifiers contained in the array 'ids'. Creates and exports a Registry instance on the local host that accepts requests on the specified port.
Creates and exports a Registry instance on the local host that uses custom socket factories for communication with that instance. Returns a reference to the remote object Registry for the local host on the default registry port of Returns a reference to the remote object Registry for the local host on the specified port.
Returns a reference to the remote object Registry on the specified host on the default registry port of Returns a reference to the remote object Registry on the specified host and port.
Returns a locally created remote reference to the remote object Registry on the specified host and port. Returns the remote reference bound to the specified name in this registry. I'm aware that you run it on remote objects, but if the remote interface s it implements has methods that don't throw RemoteException it will complain.
