Problem when I upload txt files to the server

Question

Hi, I have a problem when I try to upload files to the server, and I can't understand the fail.
My case is:
I have a jsp page where a from is.
This form is sended to a servlet that proccess its content and upload the attach file to the server.
It works correctly (it uploads the files, txt, xls and csv), the problem is when I try to upload a txt file like this, for example:
Depth     Age
0     0,1
2     0,9
3     2
5     6
6     9
8     12
34     25
56     39
101     40When I verify the uploaded file, this one has a character extra of return of line (a small square). This character prevents me from working then correctly with the file, on having detected a column of more.
Which can be the problem?
The code I use to uploaded the file is:
try
    MyConnection Objconnection = new MyConnection();
    boolean isMultipart = FileUpload.isMultipartContent(req);
    // Create a factory for disk-based file items
    FileItemFactory factory = new DiskFileItemFactory();
     // Create a new file upload handler
    ServletFileUpload upload = new ServletFileUpload(factory);
    // Set overall request size constraint
    upload.setSizeMax(1024*512); //524288 Bytes (512 KB)
     // Parse the request
    List items = upload.parseRequest(req);
    // Process the uploaded items
    Iterator iter = items.iterator();
    String dat = new String();
    String typeFile = new String();
    while (iter.hasNext())
        FileItem item = (FileItem) iter.next();
        if (item.getFieldName().equals("typeFile") )
            typeFile = item.getString();
        if (!item.isFormField())
        String fieldName = item.getFieldName();
        String fileName = item.getName();
        String contentType = item.getContentType();
        boolean isInMemory = item.isInMemory();
        long sizeInBytes = item.getSize();
        int numbers=0;
        for(int i=fileName.length();(i=fileName.lastIndexOf('\\',i-1))>=0;)
             numbers++;
        String stringFile[] = fileName.split("\\\\");
        HttpSession session = req.getSession(true);
        String loginSesion = (String)session.getAttribute("UserLogin");
        String newUserFolder = loginSesion;
        File createFile = new File("/usr/local/tomcat/webapps/Usuarios/FilesUp/"+newUserFolder);
        if ("AgeModel".equals(typeFile))
            createFile = new File("/usr/local/tomcat/webapps/Usuarios/FilesUp/AgeModels/"+newUserFolder);
        if (!createFile.exists())
            createFile.mkdir();
        fileName = stringFile[numbers];
        File uploadedFile = new File("/usr/local/tomcat/webapps/Usuarios/FilesUp/"+newUserFolder+"/"+fileName);
        if ("AgeModel".equals(typeFile) )
            uploadedFile = new File("/usr/local/tomcat/webapps/Usuarios/FilesUp/AgeModels/"+newUserFolder+"/"+fileName);
        existe = Objconnection.existFile(fileName, typeFile, loginSesion);
        if ( true == existe )
             exito = false;
        else
            item.write(uploadedFile);
            ....// NOW REGISTER THE FILE IN TH DATA BASE
    } // if (!item.isFormField())
} // WHILE ( iter.hasNext() )
            catch(Exception e) {
            out.println("Error de Aplicaci�n " + e.getMessage());
            return exito;

Hi,
Sorry I am aware this question was posted way back, but I am having similar problem and haven't been able to find the fix yet.
So please let me known if you have got any ideas.
My problem is same that I have to upload a CSV file from Client Machine (Windows) to Unix Application Server.
I am using JSP method post and multipart/form-data (as in http://www.roseindia.net/jsp/file_upload/Sinle_upload.xhtml.shtml).
The file is uploaded fine but the problem is it displays carraige Return (^M) a square boxes on Unix file.
I can't ask user to convert file to Unox format before uploading. They just convert excel file to CSV and upload.
Is there any way I can get rid of these characters as I have to use this file further.
Sorry, I can't use any paid utility or tool for it.
I would appreciate if you could please help.
Thanks,
SW
