You can use below < select > of before < /body >

<script>
  document.getElementById('paper').value = '<%= data %>';
</script>

as suggested by @s3ib

OR

<select  name="paper" onBlur="f_papper();" >   
<option value="">---SELECT---</option> 
<option value="value1" <%if("value1".equals(data)out.print("selected='selected'");%>>item1</option>

 <option value="value2"    <%if("value2".equals(data)out.print("selected='selected'");%>>item2</option>
...
</select>

The above code is ideal if you are generating the options using loop

<select name="paper" id="paper" onBlur="f_papper();" >
  <option value="">---SELECT---</option>
  <option value="value1">item1</option>
  <option value="value2">item2</option>
  <option value="value3">item3</option>
  <option value="value4">item4</option>
  <option value="value5">item5</option>
  <option value="value6">item6</option>
  <option value="value7">item7</option>
</select>

<script>
  $('#paper').val('<%= data %>');
</script>

This would be one way of doing it using jQuery.

EDITED: Or if you dont want to use jQuery, you can use pure JavaScript also like that:

<script>
   document.getElementById('paper').value = '<%= data %>';
</script>

thanks @Tarmo i really get the task done..by ur help – RaviN Feb 04 '14 at 07:29 — RaviN, Feb 04 '14 at 07:29
