<html>
<head><title>Create Person</title></head>
<body>
<h1>Enter your details</h1>
<form action="listPageParameters.jsp" method="post">
<table>
<tr><td>First name:</td> <td><input type="text" name="firstName" /></td></tr>
<tr><td>Last name:</td> <td><input type="text" name="lastName" /></td></tr>
<tr><td>Age:</td> <td><input type="text" name="age" /></td></tr>
</table>
<input type="submit" value="Submit details" />
</form>
</body>
</html>
3.2 이 부분에서 폼 값이 없을경우 기본값을 출력하고 있다.
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<html>
<head><title> Display details</title></head>
<body>
<h1>Your details (or, the details that you entered!)</h1>
<table>

<tr><td>Partner's age</td>
<td><c:out value="${param.partnerAge}">
Unknown age
</c:out>
</td>
</tr>
</table>
</body>
