Unable to connect to ftp server java

Question
I should be able to successfully send and receive file to/from FTP server.
But then, no changes occurred in the code and I started getting this :
Error: java.net.ConnectException: Connection timed out: connect
What I am doing is:
FTPClient ftp = new FTPClient();
ftp.connect( IPADDRESS of FTP server);
connect()
is giving this execption. I am not understanding the cause for it.
Solution
The error message is telling you that the OS's attempt to connect to the server timed out. This typically means that:
- the remote server has dropped off the network, or
- something (e.g. a firewall) is "black holing" packets sent to the server on the FTP port.
OTHER TIPS
Signals that an error occurred while attempting to connect a socket to a remote address and port. Typically, the connection was refused remotely (e.g., no process is listening on the remote address/port).
