FTP connection without proxy

I have a system, where we were sending files by FTP transfer through Proxy. Now i need to make a change to send the files with or without Proxy.

I tried just creating an FTPClient connection without host and port values and also without user id and pwd. like client = new FtpClient();

Alone this makes sending the files without Proxy?

I read about Proxy.Type.DIRECT, not understanding the usage of that whether i should apply for my requirement.

Solution

  • From your code, it seems that you are using an FTP proxy (not a normal proxy).

    client = new FtpClient(proxy, Integer.parseInt(port));  
client.login(username+"@"+host, password);

    If you want to connect directly, connect to the host, not proxy. Also I assume that the actual username of the target host is just a username. The FTP proxy uses a username in format username@host to tell, what host it should forward the connection to.

    client = new FtpClient(host, Integer.parseInt(port));  
client.login(username, password);

    Not sure about the port. If your FTP proxy uses a non-standard port, you probably should not use the port, but connect to a standard FTP port 21.
