Using jfilechooser

hi all,
how to use jfilechooser to select a file available in another computer of my LAN.
i used setFileSelectionMode(JFileChooser.FILES_ONLY);with this statement, if i give 'c:' or any local/mapped drive names in text box, it lists the files properly and i can choose the file.
but, if i give the IP address of another system, i.e like '\\192.168.0.243', it simply accepts this (\\192.168.0.243) as filename and closes the file chooser dialog. if i type the ip address, the file chooser should list the shared drives in that system. how to do this?
i tried java.awt.filedialog, but it does this, but supports only single file selection
thanking you.

Cross-posting and not saying in the post that you are cross-posting is even worse. (Cross-posts are often removed from these forums).

File size using JFileChooser

Hi,
I have a File[] array (with directories and files on it), and want to take to another array the size of files only. I don't want to use File.length, because in this way i take the size of directories too.
I tried to use this:
for(int i=0; i<array.length; i++)
File f = new File(path, array.toString());
Size[i]=f.length();
}//for
but i don't think is good to have a Size array with "zeros" (when it finds directories) and long values (when it finds files).
What do you propose me to do?
Would it be good to use JFileChooser and how?
Thanks,
TSolonel

What do you want to do with that array? Why not having a File[] array, so you have both length and isDirectory info. Sorting? Something else? JFileChooser seems irrelevant. But again, it's all up to what you are trying to do. Clarify

How to get the file path of selected file using JFileChooser

Hi All,
I am trying to store the file on my FTP server after selecting the file from the user workstation using JFileChooser. But I am not able to write the file on FTP server or on user local machine where application is running. I am new to this FTP server coding. Can anyone help me in this.
This is the code I wrote on button click user will able to select the file:
String filename1;
File file;
JFileChooser fc = new JFileChooser();
fc.showOpenDialog(this);
file = fc.getSelectedFile();
filename1 = file.getPath();
txtFilePath.setText(filename1);
Below is the code to write the file on my local machine first:
BufferedWriter outFile = new BufferedWriter( fileName ) );
outFile.write();
outFile.flush( );
outFile.close( );
Any help will be greatly appriciated

There is NOTHING named 'fileName' in any of the code you posted so that code can't possibly compile let alone actually run.
How can anyone help you if you won't post the actual code you are using?Its just a random snippet of other code that is totally irrelevant to this thread if you ask me.

Folders that having non-ascii chars are not displaying on MAC using JFileChooser

On MAC OS X 10.8.2, I have latest Java 1.7.25 installed. When I run my simple java program which allows me to browse the files and folders of my native file system using JFileChooser, It does not show the folders that having non-ascii char in there name. According this link, this bug had been reported for Java 7 update 6. It was fixed in 7 Update 10. But I am getting this issue in Java 1.7.21 and Java 1.7.25.
Sample Code-
{code}
public class Encoding {
public static void main(String[] arg) {
try {
//NOTE : Here at desktop there is a folder DKF}æßj having spacial char in its name. That is not showing in file chooser as well as while is trying to read for FILE type, it is not identify by Dir as well as File - getting File Not Found Exception
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

How to save a copy of a file to different location using jfilechooser

hi, this is ravikiran,
In my project there is a situation where when a user clicks on some button, a copy of a file(which is initially in my project folder) must be saved to a location specified by the user.
I have no idea how to do this using JFileChooser.
help me,
thanx in advance

JFileChooser lets you choose a file. Once it's done you will have to program the copy function with womething like :
     public void copyToDir(String fileSource,String fileDest) {
          try {
               FileChannel srcChannel = new FileInputStream(fileSource).getChannel();
               FileChannel dstChannel = new FileOutputStream(fileDest).getChannel();
               dstChannel.transferFrom(srcChannel, 0, srcChannel.size());
               srcChannel.close();
               dstChannel.force(true);
               dstChannel.close();
          } catch (IOException e) {
               e.printStackTrace();
     }

Using JFileChooser in GUI Builder / Matisse

Would appreciate any help with how to modify the code created by the NetBeans GUI Builder / Matisse to use jFileChooser.
I've added a Menu item to act as a file Open option, called OpenItem, and the GUI builder has added a listener which points to a method OpenItemActionPerformed:
private void OpenItemActionPerformed(java.awt.event.ActionEvent evt) {
        // TODO add your handling code here:
} I have also added a jFileChooser component, named jFileChooser1, but if I try to use it in the OpenItemActionPerformed method I get an error.
private void OpenItemActionPerformed(java.awt.event.ActionEvent evt) {
       JFileChooser1.
}     shows error: "<identifier> expected" (as soon as I get to the dot).
The variable seems to be defined:
private void initComponents() {
        jFileChooser1 = new javax.swing.JFileChooser();
}// Variables declaration - do not modify
private javax.swing.JFileChooser jFileChooser1;
// End of variables declaration
Maybe I have gone about this the wrong way, so any clues as to either how I can get the jFileChooser1 variable to work or any way I can use JFilechooser with GUI Builder created application would be much appreciated.
Thanx in advance.

The following example creates a file chooser and displays it as first an open-file dialog and then as a save-file dialog:
    String filename = File.separator+"tmp";
    JFileChooser fc = new JFileChooser(new File(filename));
    // Show open dialog; this method does not return until the dialog is closed
    fc.showOpenDialog(frame);
    File selFile = fc.getSelectedFile();
    // Show save dialog; this method does not return until the dialog is closed
    fc.showSaveDialog(frame);
    selFile = fc.getSelectedFile();Here is a more elaborate example that creates two buttons that create and show file chooser dialogs.
    // This action creates and shows a modal open-file dialog.
    public class OpenFileAction extends AbstractAction {
        JFrame frame;
        JFileChooser chooser;
        OpenFileAction(JFrame frame, JFileChooser chooser) {
            super("Open...");
            this.chooser = chooser;
            this.frame = frame;
        public void actionPerformed(ActionEvent evt) {
            // Show dialog; this method does not return until dialog is closed
            chooser.showOpenDialog(frame);
            // Get the selected file
            File file = chooser.getSelectedFile();
    // This action creates and shows a modal save-file dialog.
    public class SaveFileAction extends AbstractAction {
        JFileChooser chooser;
        JFrame frame;
        SaveFileAction(JFrame frame, JFileChooser chooser) {
            super("Save As...");
            this.chooser = chooser;
            this.frame = frame;
        public void actionPerformed(ActionEvent evt) {
            // Show dialog; this method does not return until dialog is closed
            chooser.showSaveDialog(frame);
            // Get the selected file
            File file = chooser.getSelectedFile();
    };Here's some code that demonstrates the use of the actions:
    JFrame frame = new JFrame();
    // Create a file chooser
    String filename = File.separator+"tmp";
    JFileChooser fc = new JFileChooser(new File(filename));
    // Create the actions
    Action openAction = new OpenFileAction(frame, fc);
    Action saveAction = new SaveFileAction(frame, fc);
    // Create buttons for the actions
    JButton openButton = new JButton(openAction);
    JButton saveButton = new JButton(saveAction);
    // Add the buttons to the frame and show the frame
    frame.getContentPane().add(openButton, BorderLayout.NORTH);
    frame.getContentPane().add(saveButton, BorderLayout.SOUTH);
    frame.pack();
    frame.setVisible(true);

Problem using JFileChooser

Hi,
I am encoutering a strange error dialog, javaw.exe No-Disk dialog box with this message "There is no disk in the drive. please insert a disk in drive A" when using JFileChooser.
I have been referring to some forums and understood this is a bug. But most encountered this when they are using it with Java Web Service or some web application.
I have Windows 2000 and mine is a java application. I have tried a workaround with WindowsAltFileSystemView but that does work with Windows 2000.
So is there any workaround..help needed.
thanks.

If you do not do so already, try setting a starting point for your JFileChooser.
JFileChooser chooser = new javax.swing.JFileChooser();
chooser.setCurrentDirectory( someDirectory );The "someDirestory" could be any directory you want or need depending on Platform independance or not.

Using JFileChooser to select directory only

Hi. I am using JFileChooser to let the user to select the directory to save some files into the user-selected directory. I set the JFileChooser to show only directory and not files. Below show part of my code:
private JFileChooser chooser = new JFileChooser();
chooser.setFileHidingEnabled(true);
chooser.setMultiSelectionEnabled(false);
chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
chooser.setDialogType(JFileChooser.OPEN_DIALOG);
int state = chooser.showDialog(frame, "Select Directory");
if (state == JFileChooser.APPROVE_OPTION )
file = chooser.getCurrentDirectory();
However, the File reference that i get is not the user-selected directory. Please help.
Thank you.

Hi,
i found that if user writes in the text field of save dialog name of the file(but application needs directory), getCurrentDirectory() returns correct directory. but if user chooses directory, getCurrentDirectory() returns parent directory but getSelectedFile() returns correct one, so i suggest something like this(it's nasty but it works [i hope;])
JFileChooser dirChooser = new JFileChooser("");
dirChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
if (dirChooser.showSaveDialog(this) == JFileChooser.APPROVE_OPTION)
java.io.File curDir = dirChooser.getSelectedFile().isDirectory()?dirChooser.getSelectedFile():dirChooser.getCurrentDirectory();

RMI -How to use JFileChooser to see remote computer FileSystem

i hav made a program in RMI which uses JFileChooser to show remote-machine File System. i have made my own FileSyatemView class (MyFileSyatemViewClient which extends FileSystemView) and override all the methods of FileSystemView Except getFileSystemView.
Similarly i have made my own FileView(MyFileViewClient).
i fed these to the JFileChooser. And object of JFileChooser i am recieving from the server through remote method getFileChooser(). Thus the code is like:
                         MyFileSystemViewClient mfsvc; //Defined Globally
                         MyFileViewClient mfvc; //Defined Globally
public void actionPerformed(ActionEvent ae)
if(ae.getActionCommand().equals("Open"))
                         mfsvc = new MyFileSystemViewClient();
                         mfvc = new MyFileViewClient();
try
JFileChooser jfc=fi.getFileChooser();
// "fi" is the FileInterface through which we access server-side methods.
                              jfc.setFileSystemView(mfsvc);
                              jfc.setFileView(mfvc);
                              int retval = jfc.showOpenDialog(null);
                              if(retval==JFileChooser.APPROVE_OPTION)
                                   getf = jfc.getSelectedFile();
                         catch(Exception e)
                              System.out.println("Error Occurred In OPEN :"+e);
MyFileSystemViewClient class looks as :

//.....................................................End of the MyFileSystemViewClient.......................
Thus each method in the class MyFileViewClient brings the required information from the server. BUT we are getting two problems:
1) so many folders at the server-side are shown as files in the dialogbox.
2)dialog box shows all "folders of the desktop" of the local filesystem and some more "local drives without any name". when i click a folder in the dialog box which is on my local machine, nothing happens. they are just the icon with the name but don't show the content. although i can easily see the drives of the remote filesystem and browse through except for the problem stated above at no.1.
ok guys now its your turn to speak up.....
plz give some suggestions and comments..
ciao!!

sry to all friends there who can't read the code clearly. as per the suggestion i am putting the code afresh..
the main client class which binds to the server contains following piece of code :
MyFileSystemViewClient mfsvc; //Defined Globally
MyFileViewClient mfvc; //Defined Globally
public void actionPerformed(ActionEvent ae)
     if(ae.getActionCommand().equals("Open"))
          mfsvc = new MyFileSystemViewClient();
          mfvc = new MyFileViewClient();
          try
               JFileChooser jfc=fi.getFileChooser();//Requesting JFileChooser object from server.
               // "fi" is the FileInterface through which we access server-side methods.
               jfc.setFileSystemView(mfsvc);
               jfc.setFileView(mfvc);
               int retval = jfc.showOpenDialog(null);
               if(retval==JFileChooser.APPROVE_OPTION)
               getf = jfc.getSelectedFile();

}i again like to convey that, "fi" is the FileInterface through which we access server-side methods.

Problem in using JFileChooser

Hi all
i m using JFile chooser

super.fireActionPerformed(command);
when i open the form, following exception arises.
java.io.IOException
     at sun.awt.image.GifImageDecoder.readHeader(GifImageDecoder.java:337)

File Extention when using JFileChooser

I'm using the JFileChooser and a FileFilter with for extensions of .ses, and I can't get it to append .ses to a file name if the user doesn't do it at the time they are in the File choser.
What I've tried:
JFileChooser fc = new JFileChooser();
fc.setFileFilter(new SessionFileFilter());
int retVal = fc.showSaveDialog(null);
if(retVal == JFileChooser.APPROVE_OPTION){
     f = fc.getSelectedFile();
if(!f.getName().endsWith(".ses")){
               f=new File(f.getName()+".ses");
...SessionFileChooser...
public boolean accept(File f) {
          boolean retval = false;
          int pos = f.getName().indexOf(".");
          if(pos != -1){
               if(f.getName().substring(pos).equals(".ses")){
                    retval = true;
          return retval;
     public String getDescription() {
          return ".ses";
...any help would be appreciated, if you need source that compiles i'll get some worked out...
to clarify the problem, if you go to save this web page and a dialog appears, you don't have to type .htm, but it automatically adds it before saving, this is what i'm trying to achieve.

These two classes should do it. Let me know if there are any problems
