Question

I am trying to download files from a server using FTP protocol in java.
By using following URL I am able to connect to the server & download files.

URL url = new URL("ftp://"+user+":"+password+"@"+host+"/"+remoteFile+";type=i"); 

But when my password contains the “@” (ex : soft@2011) symbol it throws the following exception:

  java.net.UnknownHostException: 2010@192.168.1.100 

It is not able to differentiate both “@” symbols.

How can I avoid this problem? Can I use any escape characters to avoid this problem?

Answer 1

URI encoding the password (and preferably the user name as well) should work just fine.

URL url = new URL("ftp://" + 
                  URLEncoder.encode(user, "UTF-8") + ":" + 
                  URLEncoder.encode(password, "UTF-8") + "@" + 
                  host + "/" + remoteFile + ";type=i");
