// assumes your RecordSet is named rs

                ResultSetMetaData md = rs.getMetaData();
                Logger.debug("Col count is " + md.getColumnCount());
                for(int i=1; i < (md.getColumnCount() +1) ; i++) {
                        Logger.debug("Column name is " + i +" "+ md.getColumnName(i));
                }
                
                

This is a quick and dirty way to log the request parameters, when using a servlet.

                Enumeration db = request.getParameterNames();
                while (db.hasMoreElements()) {
                        String foo = (String)db.nextElement();
                        Logger.debug("***********************************");
                        Logger.debug("***" + foo + " : " + request.getParameter(foo) + "***");
                        Logger.debug("***********************************");
                }
