very useful snippet:

    public static String getRequestParameters( HttpServletRequest aRequest)

   {

           StringBuffer aReturn = new StringBuffer("");

           Enumeration parameterNames = aRequest.getParameterNames();

           while (parameterNames.hasMoreElements()) {

               String requestParameter = (String) parameterNames.nextElement();

               String[] aValues = aRequest.getParameterValues(requestParameter);

               for (int i = 0; i <> 0) {

                       aReturn.append("&");

                   }

                   aReturn.append(requestParameter);

                   aReturn.append("=");

                   aReturn.append(aValues[i]);

               }

           }

           return aReturn.toString();

       }
