Reconnect RMI client after server restart

I have an RMI server and a desktop RMI client. When I restart the server, I get errors in the client. Is it possible to restart the RMI connection without restarting the client?

[EDIT] Here is the stacktrace:

java.rmi.ConnectException: Connection refused to host: xxx.xxx.xxx.xxx; nested exception is: 
    java.net.ConnectException: Connection refused: connect

回答1:

When the server is terminated, you will receive a ConnectException. After that you can just use Naming.lookup to get a new server object.

回答2:

If you're using Spring (namely RmiProxyFactoryBean), you can simply set the property refreshStubOnConnectFailure to true and the bean will survive a restart of the server.

<property name="refreshStubOnConnectFailure" value="true" />
