title: Update particular record on click of specific submit button
body: <p>I have a Jsp page which displays several records from database and with each data row there is a submit button on its click servlet updates the database.</p>
  
  <p>For example my JSP displays:-
  CustomerName  Customer City   SubmitButton.</p>
  
  <p>So I want that submit button next to whichever customer is pressed the data for that customer should be updated.</p>
  
  <p>I m able to display the data in jsp with submit buttons but not able to update the records from servlet.</p>
