2 simple ways to do this. 1st you can incorporate javascript inside in your jsp. Then create function that would hide your the field that can be editted if the user is not admin.(Then show only the read-only or text field) Then show it otherwise which seemed a little complicated this way. But anyway, 2nd is you can use jsp standard tag library or jstl.. use . It works like a switch with case statements :) for reference please see: http://www.tutorialspoint.com/jsp/jstl_core_choose_tag.htm

if you want do this as other said, you must have a database gestion, anyway the code that you must have is like:

<input id ="label1" value="http://google.com" class="form-control" readonly></div>
<script type="text/javascript">
  var isAdmin = "1" //this variable must be valorized with a flag or something that is supposed to be, for example 0 for users 1 for admins

  if(isAdmin==1){
    var checkVisible = document.getElementById("label1");
    checkVisible.readOnly= false;
  }
</script>

for sure it's not a professional solution but this can give to you and idea how it works
