Hi,
I am running RMI on Apache Server. The server I am running RMI on is Windows NT and it had dynamic IP. It used to work absolutely perfect. But now we changed our network and that server has got a static IP but now since then I am not able to run RMI on that server. As and when I try to login using RMI..It gives the following error messages.

Hi Pratik,
Here is what happens : when the RMI client wants to fetch the class definition of the stub from the Apache server, the connection to the Apache server fails.
Possible reasons :
1- DNS problem : the host name pratik cannot be resolved to the IP address of the Apache server
--->replace the name pratik by the actual IP of Apache server
2- The Apache server is not running or is running at a port different from 80
----> try : telnet apache_server_ip 80
3- either 1 or 2
Regards
