I am building a simple application for sending and receiving mails using Java Mail API.
I am using a proxy server for connecting to the internet. We are having a LAN connection. When I run a simple send message application on the PC which is directly connected to internet the application RUNS FINE.
But when I run it on a pc which is on the LAN and using proxy server for internet connection, the example DOES NOT WORK and THROWS EXCEPTIONS.
Does anyone know how to do the settings if one is proxy server?
Can anyone please help me?
Thanks in advance.

More probably you need to mess with the LAN and server not your code...
What you would have to do relates specifically to how the network is set up. I have written Net apps that work fine on my modem link at home as well as the LAN in work.
It could be a lot of things�..perhaps you only have access to port 80 for internet�nothing else? It�s hard to pin down without knowing the LAN.

Thanks for the reply.
You are right pal I know I dont have to mess with code. I know that the problem is with LAN settings in Windows NT.
We are using port 81 for internet connection. Do u think there is any problem with port 81?
Where exactly do u think is the problem? I am not much familiar with LAN and networking.
Can u help?

Hmm....
You say you have a prog that sends and recieves mails huh??
Therefore I assume you are using SMTP and POP3??
Open Telnet, and connect to your mailserver for sending on port 25. If you connect you should get a reply with "250" in it. Do the same for your POP3 server, but this time connect to port 110.
In the reply you should get a response with "+OK" in it.....
If for whatever reason you can't do the above, then it could be that your LAN has a firewall that is blocking those ports....If this is the case - your stuck. No mail programs will be able to access these ports.
If you can connect to these ports then....???
