Problem with added carrige returns in download of fixed length records.

Question

Hi,
I'm hoping that someone can help me, I'm at a complete loss.
I am downloading fixed length text records from our extranet via JSP. The problem is that 8 addtional carrige returns are being added to the records somewhere during this process, rendering the files useless. The following is the code I'm using
<%
FileInputStream fInputStream = null;
String piccareD = "/usr/local/apache/tomcat/webapps/piccare/";
String filePath = piccareD + "x/" + request.getRemoteUser() + "/dnload/";
String fileName = request.getParameter("fileName");
int ch;
String dnloadFile = filePath + fileName;
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment;filename=" + dnloadFile);
Connection con = ConnectionServlet.getConnection();
try
  fInputStream = new FileInputStream(dnloadFile);
  while ( (ch = fInputStream.read() ) != -1)
      out.write(ch);
  log.logEvent(con, LogElement.DNLOAD, fileName);
  log.setRetrieved(con, fileName, tStamp.getStamp());
  if( ! (fileName.indexOf("archive/") > -1) )
       String proc = "mv " + dnloadFile + " " + filePath + "archive/" + fileName;
       Process mv  = Runtime.getRuntime().exec( proc );
       Thread.sleep(100);
       int ec = mv.exitValue();
       mv.destroy();
       System.err.println( ec );
       if( ec != 0 )
} catch (Exception e) {
        System.err.println(e.getMessage());
        log.logEvent(con, LogElement.DNLOAD_ERR, fileName);
%>Any help is sincerely appreciated.
Thank you!

You might try setting the buffer size to 0 for the jsp page and see if that helps.
