problem to create FTP client

[Zoran Jeremic]

Hi,
   
  I'm using a commons-net to upload an ArgoUML project (archive with extension 
.zargo) and its class diagram as picture (.png) to the remote FTP server. Its 
works fine in case FTP client and FTP server are on the same PC. However, if 
the FTP client is on other PC it also upload both files picture and project to 
the FTP repository but those files has only 1 kb instead of 5 or more and are 
unreadable. 
Here is the code:
   
  public void createConnectionToFTPServer(String host,String username, String 
password){
 
 try{
 ftp.connect(host);
 ftp.login(username, password);
 int reply=ftp.getReplyCode();
  if(FTPReply.isPositiveCompletion(reply)){
      LOG.info("Connected Successfully to the FTP server");
  }else{
      LOG.info("Connection to the FTP server Failed");
      ftp.disconnect();
  }
  ...
  public void uploadFileToRepository(File file,String filename){
    try{
 ftp.setFileType(FTP.IMAGE_FILE_TYPE);
 LOG.info("uploadFileToRepository");
    InputStream fis = new FileInputStream(file);
 OutputStream os = ftp.storeFileStream(filename);
 int t=0;
        while( (t=fis.read()) >=0){
            os.write(t);
        }
 }catch(IOException ioe){
 ...
 
 public void closeConnection(){
    try{
    ftp.disconnect();
....
  I hope that somebody has an idea what can be problem.
   
  Thanks
Zoran
