RMI -How to use JFileChooser to see remote computer FileSystem

Question

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 :
public class MyFileSystemViewClient extends FileSystemView
               public MyFileSystemViewClient()
                    //super();
                    try{
                    fi.invokeMyFileSystemViewCons();
                    }catch(Exception e){
                         System.out.println("Error in invokeMyFileSystemViewCons : "+e);
               public File[] getFiles(File file,boolean tr)
                    try{
                    return fi.getFiles(file,tr);
                    }catch(Exception e){
                         System.out.println("Error in getFiles : "+e);
                         return null;}
               public File getHomeDirectory()
                    try{
                    return fi.getHomeDirectory();
                    }catch(Exception e){
                         System.out.println("Error in getHomeDirectory : "+e);
                         return null;}
               public File getParentDirectory(File dir)
                    try{
                    return fi.getParentDirectory(dir);
                    }catch(Exception e){
                         System.out.println("Error in getParentDirectory : "+e);
                         return null;}
               public File[] getRoots()
                    try{                         
                    return fi.getRoots();                    
                    }catch(Exception e){
                         System.out.println("Error in getRoots : "+e);
                         return null;}
               public File getDefaultDirectory()
                    try{
                    return fi.getDefaultDirectory();
                    }catch(Exception e){
                         System.out.println("Error in getDefaultDirectory : "+e);
                         return null;}
               public File createNewFolder(File containingDir)
                    try{
                    return fi.createNewFolder(containingDir);
                    }catch(Exception e){
                         System.out.println("Error in createNewFolder : "+e);
                         return null;}
               public String getSystemDisplayName(File f)
                    try{
                    return fi.getSystemDisplayName(f);

                    }catch(Exception e){
                         System.out.println("Error in getSystemTypeDescription : "+e);
                         return null;}
               public File getChild(File parent, String fileName)
                    try{
                    System.out.println("Child FIle : "+fi.getChild(parent,fileName));
                    return fi.getChild(parent,fileName);
                    }catch(Exception e){
                         System.out.println("Error in getChild : "+e);
                         return null;}
               public boolean isParent(File folder,File file)
                    try
                         return fi.isParent(folder,file);
                    catch(Exception e)
                    System.out.println("Error in isParent : "+e);
                         return false;     
               public Icon getSystemIcon(File f)
                    try{
                    return fi.getSystemIcon(f);
                    catch(Exception e)
                    System.out.println("Error in getSystemIcon : "+e);
                         return null;     
               public boolean isDrive(File dir)
                    try{
                    return fi.isDrive(dir);
                    catch(Exception e)
                    System.out.println("Error in isDrive : "+e);
                         return false;     
               public boolean isFileSystem(File f)
                    try{
                    return fi.isFileSystem(f);
                    catch(Exception e)
                    System.out.println("Error in isFileSystem : "+e);
                         return false;     
               public boolean isFileSystemRoot(File dir)
                    try{
                    return fi.isFileSystemRoot(dir);
                    catch(Exception e)

//.....................................................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!!

Answer 1

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();
          catch(Exception e)
          System.out.println("Error Occurred In OPEN :"+e);
}i again like to convey that, "fi" is the FileInterface through which we access server-side methods.
MyFileSystemViewClient class looks as :
public class MyFileSystemViewClient extends FileSystemView
               public MyFileSystemViewClient()
                    //super();
                    try{
                    fi.invokeMyFileSystemViewCons();
                    }catch(Exception e){
                         System.out.println("Error in invokeMyFileSystemViewCons : "+e);
               public File[] getFiles(File file,boolean tr)
                    try{
                    return fi.getFiles(file,tr);

                         System.out.println("Error in getFiles : "+e);
                         return null;}
               public File getHomeDirectory()

               public boolean isFileSystemRoot(File dir)
