Hi
Got a big problem with this servlet
In one of the cycles suddenly it stops with not apparent reason

this is the code:

try
       {

           FileOutputStream fileoutputstream = new
FileOutputStream(path + "NHOOOLF01.html");
           out = new PrintWriter(fileoutputstream);
           out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0
TRANSITIONAL//EN\">");
           out.println("<HTML>");
           out.println("<HEAD>");
           out.println("<title>SIAS</title>" );
           out.println("<meta http-equiv=\"Content-Type\"

                  out.println("</table>");
                  out.println("</body>");
                   out.println("</html>");

      }

and this is the end of the output ... when it stops not completing the
html
any idea?
Thanks Gianni
