Specified file not found

Hi,
I am using org.apache.commons.net library for ftpclient.When I try to access the directory in the ftp server I get the 550:The specified file not error.But that file is there in the ftp server.
The code written is given below:

package com.ftp;

import java.io.IOException;

import org.apache.commons.net.ftp.DefaultFTPFileListParser;
import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPFile;
import org.apache.commons.net.ftp.FTPFileEntryParser;
import org.apache.commons.net.ftp.FTPFileEntryParserImpl;
import org.apache.commons.net.ftp.FTPFileList;
import org.apache.commons.net.ftp.FTPListParseEngine;
import org.apache.commons.net.ftp.parser.CompositeFileEntryParser;
import org.apache.commons.net.ftp.parser.DefaultFTPFileEntryParserFactory;
import org.apache.commons.net.ftp.parser.FTPFileEntryParserFactory;
import org.apache.commons.net.ftp.parser.VMSFTPEntryParser;



public class FtpCrawler {

static FTPClient ftp=new FTPClient();
public static void main(String[] args) {
try {

String server="10.16.56.216";

String directory="/lib/account lib/";
ftp.connect(server);
ftp.login(args[0],args[1]);
FTPFile[] files=ftp.listFiles(directory);

for(int i=0;i<files.length;i++){

}


System.out.println("Connected to " + server + ".");
System.out.print(ftp.getReplyString());






ftp.disconnect();

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}


}
