    Default forced HTTP 500 error

    Hi all,

    I would like to ask for some help.

    I made a java servlet. It receives information from sender through http get/post and it processes the information (for example it store received data to database).

    My problem is how can I throw back an http 500 exception to the sender if there is an error during data processing?

    My code:
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
        {
            ...
            PrintWriter out = response.getWriter();
            try
            {
                ...
     
                Integer[] i = new Integer[1];
     
                // it will throw an exception
                i[5] = Integer.valueOf(5);
     
                // out.println("ok");
            }
            catch (Exception ex)
            {
               // TODO to write: send back HTTP 500 error
     
                throw new ServletException(ex);
            }
            finally 
            { 
                out.close();
            }
        }

    Thank you, alma

    Default Re: forced HTTP 500 error

    Why would you want to send that sort of header under these circumstances? It might be better to send a more informative response that notifies the user - perhaps one that might not drive a user away. That being said, you can modify the header information using the HttpServletResponse object setHeader method.
