Highlight the Field in Validation

My jsp page gets validated fine and it displays errors. I am using server-side validation of struts.

The question I have is suppose there is a text field for example say: "LastName" If I do not fill it shows "Last Name is Required" But can any one help me that when this error is displayed, I also want to highlight the field with an "yellow" or any color. How can we do this on struts?

Thank you very much for your time in advance.

In order to do this, you will have to use javaScript, but Struts can certainly do some of the work. Here's one way to do it:

in your Action class:

errors.add("lastName", new ActionMessage("error.lastname");

in your jsp:
function init() {
<logic:messagesPresent property="lastName">
document.getElementById("lastNameLabel").style.color = "yellow";
<html:form action="myaction" on load="init()">
<div id="lastNameLabel">Last Name:</div>
<html:text property="lastName"/>
