JavaServer Page Example

Here is an example JavaServer page that checks the date of a specific location using a typical HTML web page form:

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core
"
         prefix="c" %>
<%@ taglib uri="/functions" prefix="f" %>
<html>
<head><title>Localized Dates</title></head>
<body bgcolor="white">
<jsp:useBean id="locales" scope="application"
    class="mypkg.MyLocales"/>

<form name="localeForm" action="index.jsp" method="post">
<c:set var="selectedLocaleString" value="${param.locale}" />
<c:set var="selectedFlag"
     value="${!empty selectedLocaleString}" />
<b>Locale:</b>
<select name=locale>
<c:forEach var="localeString" items="${locales.localeNames}" >
<c:choose>
    <c:when test="${selectedFlag}">
        <c:choose>
            <c:when
                 test="${f:equals(selectedLocaleString, localeString)}" >
                <option selected>${localeString}</option>
            </c:when>
            <c:otherwise>
                <option>${localeString}</option>
            </c:otherwise>
        </c:choose>
    </c:when>
    <c:otherwise>
        <option>${localeString}</option>
    </c:otherwise>
</c:choose>
</c:forEach>
</select>
<input type="submit" name="Submit" value="Get Date">
</form>

<c:if test="${selectedFlag}" >
    <jsp:setProperty name="locales"
        property="selectedLocaleString"
        value="${selectedLocaleString}" />
    <jsp:useBean id="date" class="mypkg.MyDate"/>
    <jsp:setProperty name="date" property="locale"
        value="${locales.selectedLocale}"/>
    <b>Date: </b>${date.date}</c:if>
</body>
</html>

The example is from the Java EE Tutorial
