The text that you want to display, will it come from the server. — Uchenna Nwanyanwu, Jul 06 '12 at 13:33

You can do this

<div id='myDiv'></div>

<input id='myButton' type='button' value='My Button' />

<script type="text/javascript">
$('#myButton').click(function()
{

$("#myDiv").html("The text that you want to display");
});
</script>

There is no such event system in servlet/JSP. In fact you may pass key-value pair data along with the servlet request.

sample.jsp

<form method="post" action="servlet_url">
  <input type="submit" name="cmd" value="Add"/>
  <input type="submit" name="cmd" value="Delete"/>
</form>

and code in doPost of servlet

String cmd=request.getParameter("cmd");
if(cmd.equals("Add"))
  {
   //
  }
else
if(cmd.equals("Delete"))
 {
 //
 }
