Java EE (Java Enterprise Edition) General Discussion

When I try to send mails through a proxy server, I get the following exception :

javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 25;
  nested exception is:
        java.net.SocketException: Malformed reply from SOCKS server

What is this "Malformed reply" ?
My program initially had worked. And I modified it to use through a proxy. The problem started since then....
I haven't tried retrieving, I guess there will be the same problem....

Please somebody reply......ASAP.............

thanks......
