you won't parameter names in order using request.getparameternames(); .

you can either utilize

string [] parameternames = new string[]{"param1","param2","param3"}; for(string param : parameternames){ system.out.println(param); }

where parameternames conains sequence in want parameters. can configure , read sequence config file.

or

you can utilize

request.getquerystring() querystring, while using method

or

you can utilize

request.getinputstream() querystring, while using post method , parse raw info query string.

after getting query string , can split , utilize way want.
