When a Java RMI client invokes a remote method using a reference that contains an unresolvable server hostname, the client will throw an
UnknownHostException.銆?/span>In order to generate functional remote references, Java RMI servers must be able to supply a fully qualified hostname or IP address that is resolvable from all Java RMI clients (an example of a fully qualified hostname is foo.bar.com). If a Java RMI program provides a remote callback operation, then that program serves a Java RMI object and consequently, must be able to determine a resolvable hostname to use as its server hostname in the remote references it passes to Java RMI clients. VMs that make calls to applets that serve remote objects may throwUnknownHostExceptions because the applet has failed to provide a usable server hostname.
If your Java RMI application throws an UnknownHostException, you can look at the resulting stack trace to see if the hostname that the client is using to contact its remote server is incorrect or not fully qualified.銆?nbsp;If necessary, you can set the java.rmi.server.hostname property on the server to the correct IP address or hostname of the server machine and Java RMI will use this property's value to generate remote references to the server.銆?/strong>
