Find file on a server with FTP

[tomitzel]

I'm making a FTPClient using the Apache library org.apache.commons.net.ftp
I made this function, which doesn't work correct because it goes to the "deepest" folder in the server and I don't know how to get back to try the other folders.

public static String isFile(String file, String director) throws IOException{
		
		ftp.changeWorkingDirectory(director);
		FTPFile f[] = ftp.listFiles();
		sortByDirectory(f);
						
	  for(int i = 0; i < f.length; i++){		  
		  if(f[i].isDirectory()){
			  return isFile(file, f[i].getName());
			
		  }
		  else
			  if(f[i].getName().equals(file))
				  return director;
				
	  }
		return "";	
	}

	}

How are u invoking the isFile() ... I dont understand..

is this a normal function or something else..

Maybe I thing i gotta learn many things from you bro.

isFile() is going to return the directory where the file is found, but this is just a prototype/ideea.
If the file isn't found anywhere, I return an empty string. (return ""; )
In my main function, I'm saving the result in a String variable, and check for the blank string.

I'm a beginner also...I just got hired at a small programming company and have a deadline

You could try to open the site in Internet Explorer and use CTRL-F.

Dude I have asked it to my friends about this problem of yours.. and well his vague idea is that why dont you simply open the file by using the html command <input type='file'> if you are using servlets ... and he says isFile() is usually used to distinguish between directory and file...it rearly helps in browsing the files on server..

I think there's a confusion... I'm not using the function isFile from the Apache library, I just defined my own function as isFile ...
I don't understand how that HTML code can help me find a file, my problem is to browse within folders/subfolders when you don't have any idea how the structure looks like.
Thanks anyway, turns out I don't need that function after all because our application will have a DB Server which will contain all the FTP links for all the files.
I just need to make a function which would verify is the link is valid.
