Thread: JFileChoose and FileOutputStream, nothing is being saved

Hey I'm pretty lost, hence my username, but I have this code here:

package downloadtesting;
import java.io.*;
import java.net.*;
import javax.swing.JFileChooser;
 
public class FileDownLoader {
    private JFileChooser jfc;
    public boolean saveUrl(String urlString) throws MalformedURLException, IOException {
        BufferedInputStream in = null;
        FileOutputStream fout = null;
    	jfc = new JFileChooser();
        if(jfc.showSaveDialog(null) == JFileChooser.APPROVE_OPTION){
            try {
                File selectedFile = jfc.getSelectedFile();
                in = new BufferedInputStream(new URL(urlString).openStream());
                fout = new FileOutputStream(selectedFile);
                byte data[] = new byte[1024];
                int count;
                while ((count = in.read(data, 0, 1024)) != -1) {
                    fout.write(data, 0, count);
                }
            }
            finally {
                if (in != null)
                        in.close();
                if (fout != null)
                        fout.close();
            }
            return true;
        } else {
            return false;
        }
    }
}

Which I'm trying to use to download a .jar file from my shell account for testing, however nothing is even being saved.

So what I'm trying to do is have this class/method download a jar file from my webhost and save it to where I specify with JFileChooser.showSaveDilog, however nothings even being saved, stuck and help much appreciated.

Are there any exceptions being thrown? If so, please post the full error message

I'm wishing I knew how to save files too. It must be very advanced Java to save them, because I've tried lots of things.



How do you write a JPanel to a file?

How do you write a JPanel to a file?

You really should start a separate thread for that question. Suffice to say that JPanel implements Serializable. And take a look at ObjectOutputStream.

Actually, the code works fine... The file I was trying to grab I forgot I had changed the name, sorry about this..
