Provide an implementation for each remote method
The implementation class must provide a method for each method name specified in the Remote interface. (Other methods may also be given, but they will only be available locally from other server classes.)
Note that any objects to be passed as parameters or returned as values must implement the java.io.serializable interface. Most of the core Java classes in java.lang and java.util, such as String, are serializable. public String sayHello() throws RemoteException { return “Hello, World! From” + name; }
