Hi

I am trying on FTP

I struck at listing the files of a directory...i can list the normal files ..here is the sample code for that:

Code

GeSHi (java):
 String ftpHost = "123.xx.xx.yyy";  //hostipadress
     String ftpUserName = "abcdef";  //username
     String ftpPassword = "passwoed";
     FTPClient ftp = new FTPClient();
    ftp.connect(host);
            ftp.login(user,pwd);
   String name[] = ftp.listNames();
   if(name.length > 0)
        {
          for( int i=0; i<name.length; i++ ){
 
        out.println(name[i]);
}
}

Try the code below, it logs into the ftp server and lists the files in the directory and also saves the structure on the disk ( c:\ftpFile.txt )

Code

GeSHi (java):
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.ObjectOutputStream;
import java.io.PrintStream;
import java.net.URL;
import java.net.URLConnection;
import java.util.Scanner;
import java.util.Vector;
 
public class FileDirectoryStructure {
	static int j = 0;
	static int k = 0;
	static String userDir = System.getProperty("user.dir");
	static String urlToSave = "c:\\ftpFile.txt";
	public static void main(String[] args) {	
		copyRight();
		System.out.println("###############\n" + 
				"#Example usage#\n" + 
				"FTP username:\t\tyourusername\n"+
				"FTP password:\t\tyourpassword\n"+
				"Host:\t\t\tengineeringserver.com\n"+
				"Directory to scan:\tpublic_html\n"+
		"##############\n");
		FileDirectoryStructure fds = new FileDirectoryStructure();
 
		Scanner sc = new Scanner(System.in);
		System.out.print("FTP username: ");
		String userName = sc.next();
 
		System.out.print("FTP password: ");
		String userPassword = sc.next();
 
		System.out.print("Host: ");
		String userHost = sc.next();
 
 
		System.out.print("Directory to scan: ");
		String userDirectory = sc.next();
 
		System.out.print("Making connecting, please wait.\n\n");
 
		fds.connectToFTPAndSaveStructure(userName,userPassword,userHost,userDirectory);
 
		//fds.scanLocalDisk();
	}
 
	public void connectToFTPAndSaveStructure(String userName, String userPassword, String userHost, String userDirectory){
		try {
			byte[] buf = new byte[4096];
			URL u = new URL("ftp://" + userName + ":" +userPassword + "@" +userHost +":21/" + userDirectory);
			URLConnection uc = u.openConnection() ;
			uc.setDoInput(true);
			InputStream in = uc.getInputStream() ;
 
			File saveFiles = new File(urlToSave);
			if(!saveFiles.exists()){
				saveFiles.createNewFile();
			}
 
			FileOutputStream saveFile = new FileOutputStream(urlToSave);	
			ObjectOutputStream OS = new ObjectOutputStream(saveFile);
			for(int i = in.read(buf); i > -1; i = in.read(buf)){
				System.out.write(buf, 0 , i);		
				PrintStream d = new PrintStream(OS);
 
				d.write(buf, 0 , i);
			}			
			in.close();
			OS.close();
			System.out.println("File saved!");
 
		} catch (IOException e) {
			//e.printStackTrace();
			System.out.println("Something happened, please check for correct input!");
		}
	}
 
	public static void copyRight(){
		System.out.println("*****************");
		System.out.println("FTP Directory Structure");
		System.out.println("By: HappyFace @ www.engineeringserver.com");
		System.out.println("This is a FREE version, but do not distribute without license!");
		System.out.println("Contact mail: info@engineeringserver.com");
		System.out.println("Ver: 02/April/2008");
		System.out.println("*****************");
		System.out.print("\n");	
	}
