Hi
I built an app based on RMI. Client (which is applet) connects to a server and sends it's own stub so the server could also invoke client methods.

Everything works fine as long as client machine has public IP.
But when he has not:

java.rmi.ConnectException: Connection refused to host: <here is client IP>;
nested exception is: java.net.ConnectException: Connection timed out
at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:574)
at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:185)
at sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:171)
at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:94) ...

This exception occurs when server for the first time tries to invoke remote method of the client.

Is there any solution for this problem?
Thanks in advance.

Sun's RMI FAQ has a section on workarounds for firewalls.
 
If you send is by car it's a shipment, but if by ship it's cargo. This tiny ad told me:
