    What do you mean by "continuous value without refreshing"? – Jon Skeet May 17 '11 at 17:21

    Start learning Ajax. You can find here some kickoff examples to build further on: http://stackoverflow.com/questions/4112686/update-current-page-with-a-servlet – BalusC May 17 '11 at 17:30
  • @umar: Okay, so that's periodically updating... I'm finding it hard to guess what you then want to store in the database... – Jon Skeet May 17 '11 at 17:32
  • My answer with that Q. already answers you. please re read it. – jmj May 17 '11 at 17:32
  • @Jon Skeet performing some test work on google app engine . creating some sensor type of data for it . – umar May 17 '11 at 17:34
  • @umar: That's still *way* too vague. You're showing lots of numbers. Which one do you want to store in the database? And where do sensors come into play? Please read http://tinyurl.com/so-hints – Jon Skeet May 17 '11 at 17:38
  • Possibly not accurate way but i have find this shortcut <%response.setIntHeader("Refresh",1); %> <%= (int) (Math.random() * 10) %> – umar May 17 '11 at 18:17

  • Thanks for your concern but it will only give random value for once . As i want to get same result as done in javascript http://jsfiddle.net/mattball/c9t3T/ ie values are constantly changing – umar May 17 '11 at 17:27
