It's a bit flakey to do in JavaScript (better to do it in Java) but here's an example of how to in JavaScript

    if ( new Date(document.frmTest.startDate.value) > new Date( <%= dbDateValue %> ) ){
        alert ("Start Date is greater");
    }

you will need to convert the db date to the correct string version so that JavaScript can understand it. For this you will need to use the SimpleDateFormatter in your Java code like this

Format formatter = new SimpleDateFormat("dd/MM/yyyy");
String s = formatter.format(date); //where date is your date object from the db
// s = "01/11/2006"

<%
String restric-date = rs.getString("RESTRIC_DATE");
SimpleDateFormat fmtDate = new SimpleDateFormat("yyyy-mm-dd HH:mm:ss.S");
Date dtNow = new Date();
Date dtRestricDate = fmtDate.parse(restric-date);

if (dtRestricDate.compareTo(dtNow) < 0) { %>
<SCRIPT...>
    alert("Your alert message here.");
