file upload (evt. via ftp)

jeg lavede engang denne applet til et andet spørgsmål:

import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;

import javax.swing.*;

public class UploadManagerApplet extends JApplet implements ActionListener {
    private final static String UPLOAD_URL = "http://localhost/upload.asp";
    private JButton select;
    private JTextArea files;
    private JButton upload;
    private String dirname;
    private String[] filenames;
    public void init() {
        getContentPane().setLayout(new BorderLayout());
        select = new JButton("Select dir");
        select.addActionListener(this);
        getContentPane().add(select, BorderLayout.NORTH);
        files = new JTextArea();
        getContentPane().add(new JScrollPane(files), BorderLayout.CENTER);
        upload = new JButton("Upload");
        upload.addActionListener(this);
        getContentPane().add(upload, BorderLayout.SOUTH);
    }
    public void actionPerformed(ActionEvent ev) {
        if(ev.getSource() == select) {
            JFileChooser chooser = new JFileChooser(System.getProperty("user.home"));
            chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
            if(chooser.showOpenDialog(this) == JFileChooser.APPROVE_OPTION) {
                File dir = chooser.getSelectedFile();
                dirname = dir.getAbsolutePath();
                filenames = dir.list();
                StringBuffer sb = new StringBuffer("");
                for(int i = 0; i < filenames.length; i++) {
                    sb.append(filenames[i]);
                    sb.append("\r\n");
                }
                files.setText(sb.toString());
            }
        }
        if(ev.getSource() == upload) {
            for(int i = 0; i < filenames.length; i++) {
                upload(dirname, filenames[i]);
            }
        }
    }
    private void upload(String dirname, String filename) {
        try {
            URL url = new URL(UPLOAD_URL + "?filename=" + filename);
            HttpURLConnection con = (HttpURLConnection) url.openConnection();
            con.setRequestMethod("POST");
            con.setDoOutput(true);
            InputStream is = new FileInputStream(dirname + File.separator + filename);
            OutputStream os = con.getOutputStream();
            byte[] b = new byte[100000];
            int n;
            while((n = is.read(b)) >= 0) {
                os.write(b, 0, n);       
            }
            con.connect();
            if (con.getResponseCode() == HttpURLConnection.HTTP_OK) {
                //JOptionPane.showMessageDialog(this, filename + " uploaded");
            } else {
                JOptionPane.showMessageDialog(this, filename + " not uploaded");
            }
        } catch (Exception e) {
            JOptionPane.showMessageDialog(this, filename + " not uploaded");
        }
    }
}

bemærk at den dog kalder et upload script. Men den kan nemt ændres til at bruge FTP
(Jakarta Commons Net har et godt FTP lib)

FTP snippet:

        FTPClient client = new FTPClient();
        try {
            client.connect("localhost");
            client.login("anonymous", "arne@");
            InputStream is = new FileInputStream("C:\\z.zip");
            client.setFileType(FTPClient.BINARY_FILE_TYPE);
            OutputStream os = client.storeFileStream("z.zip");
            byte[] b = new byte[1000];
            int n;
            while((n = is.read(b)) >= 0) {
                os.write(b,0,n);
            }
            os.close();
            is.close();
            client.disconnect();
        } catch (SocketException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

har ikke den store erfaring med java, har du det eventuelt samlet og klar til brug. Eventuelt mod en lille betaling?

hej.. har købt noget software fra http://www.somethingjava.com så det er ikke længere relevant.

smid  et svar, så får du point :)

ok

så mangler du bare at acceptere svaret
