1. overview of the java chat application

Server, which implements a remote chat with hot moms. Define the remote interface A remote object is an instance of a class that implements a remote interface. A remote interface extends the interface java. Remote and declares a set of remote methods. Each remote method must declare java.

RemoteException or a superclass of RemoteException sydney shemale chat its throws clause, in addition to any application-specific exceptions. Here is the interface definition for the remote interface used in this chay, example.

Chta declares just one method, sayHello, which returns a string to the caller: package example. Remote; import java. Implement the server A "server" class, in this context, is the class which has a main method that creates an free sex chat essex vermont of the remote object implementation, exports the remote object, and then binds that instance to a name in a Java RMI registry.

The class that contains this main method could be the implementation flirty messages for her itself, or another class entirely. In this example, the main method for the server is defined in the class Server which also implements the remote interface Hello.

The jqca main method does the following: Register the remote object with a Java RMI registry Here jacx the source code for the class Server. Descriptions for writing this server class follow the source code: package example.

Registry; import java. LocateRegistry; import java.

RemoteException; import java. The method sayHello does not need to declare that it throws any exception because the method implementation itself does not throw RemoteException nor does it throw any other checked exceptions. jsca

Note: A class can define methods not specified gay chat avanue the remote interface, but those methods can only be invoked within the virtual machine running the service and cannot be invoked remotely. Create and export a remote object The main method of the server needs to create the remote object that provides the service. Additionally, the remote object must be exported to the Java RMI runtime so that it may receive incoming remote calls.

As a result of the exportObject cnat, the runtime may begin to listen on a new server socket or may sex chat with computer a shared server socket to accept incoming remote calls for the remote object. The returned stub implements the same set of remote interfaces as the remote object's class and contains the host name and port over which the remote object can be contacted.

jacw Note: As of the J2SE 5. If your application needs to support such clients, you will need to generate stub classes for the chat teen rooms objects used in the application and deploy those stub classes for clients to download. For details on how to generate stub classes, see the tools documentation for rmic [ SolarisWindows ].

For details on how to deploy your application along with pregenerated stub classes, see the codebase tutorial. Register the remote object with a Java RMI registry For a caller client, peer, or applet to be able to invoke mobile sex chat in koumae method on a remote object, that caller must first obtain a stub for the remote object. For bootstrapping, Java RMI provides a registry API for applications to bind a name to a remote object's chatt and for clients to look up remote objects by name in order to obtain their stubs.

A Java RMI registry is a simplified name service that allows clients to jaca chat a reference a stub to a remote object.

In general, a registry is used if at cha only to locate the first text sex sites object a client needs to use. Then, typically, that first object would in turn provide application-specific support for finding other objects.

For example, the reference can be obtained as a parameter to, or a return value from, another remote method call. Once a remote object is registered on the server, callers can look cideo chat the object by name, dhat a remote object reference, and then invoke remote methods on the object.

Client code:

Registry and sends invocations to the registry on server's local host on the default registry port of The bind method is then invoked on the registry stub in order to bind the remote object's stub to the name "Hello" in the registry. Note: The call to LocateRegistry. The call does not check to see if a registry is jaca chat running. If no registry is running on TCP port of the local host when the bind method is invoked, los angeles sex chat rooms swinging server will fail with a RemoteException.

The client program obtains a stub for the registry on the server's host, looks up the remote object's stub by name in the registry, and then invokes the sayHello method on the remote object using the stub. Here is the source code for the client: package example.

If no hostname is specified, then null is used as the hostname indicating that the local host address should be used. Next, the client invokes jaca chat remote method lookup on the registry stub to obtain the stub for the remote object from the server's registry. Finally, the client invokes the sayHello method on the remote object's stub, which causes the following actions to happen: The client-side runtime opens a connection to the server using the host and port information in the remote object's stub and then serializes the call data.

The server-side runtime accepts the incoming call, dispatches the call to the remote object, and serializes the result the reply string "Hello, world! The client-side boys roulette chat receives, deserializes, and returns the result to the caller.

The response message returned from the remote invocation on the remote object is then printed to System. The source files for this example can be compiled as follows: javac -d destDir Hello. Note: If the server needs to support clients running on pre See the xhat tutorial for more details. Start the Java RMI registry, server, and client To run this example, you will need to do the following:.
