Help me on HTTP PUT please

[chris B]

Please, can you help me do the following thing?   I have to write a servlet. This servlet must show an HTML form in which the user has to enter name, age and "attach" a picture. As he click upon "submit" the servlet has to get name, picture and store them in a database (the picture in a directory). I tried to use method="PUT" in form and method doPut() of HttpServlet but I can't get my servlet go into the doPut method... it "re-prints" the page with the form and does nothing. I have also a log into I try to write a message as I enter doPut, but, it seems the servlet does not enter the method ablsolutely.   This is the code:   public void doPut(HttpServletRequest req, HttpServletResponse res)              throws ServletException, IOException  {   PrintWriter toBuyer;   String operation="";   if (servletPath == null ) servletPath = req.getServletPath();   toBuyer = res.getWriter();   res.setContentType("text/html");   operation = req.getParameter ("operation ");   if (operation == null) {}   else if (operation == "testPut")    {      // to read the name       String s = req.getParameter("name");        // to read the picture... is this the way?       try       {        ServletInputStream b = req.getInputStream();        byte[] ba = null;        b.read(ba );       } catch (Exception e) {msg ("excp: "+ e.toString() ); } // msg is a method which writes to log file         ... save the picture and update db    }    else res.sendRedirect("http://java.sun.com/");    toBuyer.close();  }     I have to complete this, please help me!!!
