Problem in writing file....

Question

hi
i am using tomcat 5.0.19 what my application doing is allowing a user to upload a text file
and before processing it the file is writen to the Specified path on server directory(for backup purpose).
the problem is in writing the file. the file is written to the specified location but the size is
reduced to approx 1/3 ie a file of 100 kb to 30kb. the code which i am using is given below..
one more thing it is working fine except for one system . Is there any problem in tomcat or
the code is creating some probs...
plz help....
public void writeToFile(String fileName) throws IOException, FileNotFoundException{
          //writes Uploaded File to the Specified path on server directory;
          OutputStream bos = new FileOutputStream(fileName);
          InputStream stream = destinationNumberFile.getInputStream();
        int bytesRead = 0;
          byte[] buffer = new byte[8192];
          while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
                         bos.write(buffer, 0, bytesRead);
        //close the stream
          bos.close();
        stream.close();
     }thanks in advance..

Answer 1

if so try to call the flush() method on bos before close it.Closing implies flushing, there is no need to invoke it "by hand".
