See more:

DropDownList to show the item I selected in the list. I get it to serve the page with a request response
but it goes to the default I was hoping if someone could show me how to make the list show the Item I picked.
PS. I'm very new to programing so could you please explain what is going on as well
This is my code

<%@page language="java" contentType="text/html; charset=ISO-8859-1"
	pageEncoding="ISO-8859-1"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
<title>clock</title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
</head>
<body>
	Current date and time on server
	${requestScope.time}
	Use this form to select another format
	<form action="${pageContext.request.contextPath}/clock" method="post">
		Select format <select name="format">
			<option value="full" selected>full</option>
			<option value="long" selected>long</option>
			<option value="medium" selected>medium</option>
			<option value="short" selected>short</option>
			<option value="bad">bad</option>
		</select> and click <input type="submit" name="getTime" value="Get Time">
		
	</form>
</body>
</html>

If I understood properly, then you want to set the drop down list whatever you select before sending the request.
In that case you have to return back the selected option in response and do the following :

HTML

var textToFind = 'medium';//value read from scope variable

var dd = document.getElementById('formatId');
for (var i = 0; i < dd.options.length; i++) {
    if (dd.options[i].text === textToFind) {
        dd.selectedIndex = i;
        break;
    }
}

Note:Call this method after drop down is list
