I have set up RMI system successfully on local ubuntu srver.
Registry port 1099 and remote object export on 1100(fixed by calling super(1100))
Now I am trying to make it work on Ubuntu over internet with a public IP.
I could bind service properly with public ip.But the client applet is trying to connect to ubuntu server at random ports.
Below is the error thrown by client applet:
// Exception
network: Connecting public-ip:1100 with proxy=DIRECT
network: Connecting public-ip/cgi-bin/java-rmi.cgi?forward=1099 with proxy=DIRECT
network: Connecting public-ip:3733 with proxy=DIRECT
network: Connecting public-ip:3721 with proxy=DIRECT
//
java.rmi.ConnectException:
Connection refused to host: public-ip; nested exception is: java.net.ConnectException: Connection refused: connect at sun.rmi.transport.tcp.TCPEndpoint.newSocket(Unknown Source)Source) at java.net.AbstractPlainSocketImpl.connectToAddress(Unknown Source)
...
//
// I have only 2 ports open on server, i.e., 1099(registry) and 1100(export). How can I fix ports in applet requests such that it does always connect server on same open port?
//
//
Another issue.As I have bound service on public IP i.e. //public-ip:1099/ServiceName, a job running on server to send message to clinets is not able to make request to RMI service. public-ip URL does not work on same machine,i.e., server.Do you think I should use fixed socket factory?If so please give me code snippet and guide me how i can set it up.
