Create the Output JSP That Displays a Message
Create another JSP, showmessage.jsp, which displays a message assuming that an instance of Message called "message" exists in the request scope. There are three ways of displaying the properties of a scoped variable:
- Use an expression such as <%= message.getId()%>
- Use the getProperty tag, such as <jsp:getProperty name="message" property="name"/>
- Use strut's htmlProperty custom tag. This tag ensures that the HTML-sensitive characters such as < and > are aptly filtered for display.
Listing 2 shows how you can display the properties of Message using a combination of the three methods.
Listing 2 showmessage.jsp
<%@ taglib uri="/WEB-INF/struts.tld" prefix="struts" %>
<jsp:useBean id="message" class="Message" scope="request"/>
<html>
<head>
<title><struts:htmlProperty name="message" property="subject"/></title>
</head>
<body bgcolor="#ffffbb">
<a href="create.do?parentId=<%= message.getId()%>">
<struts:message key="showmessage.reply"/></a>
<table border="1" cellpadding="1" width="100%" bgcolor="white">
<tr>
<td><b><struts:message key="showmessage.name"/></b></td>
<td><a href="mailto:<jsp:getProperty name="message" property="email"/>">
<jsp:getProperty name="message" property="name"/></a></td>
</tr>
<tr>
<td><b><struts:message key="showmessage.when"/></b></td>
<td><jsp:getProperty name="message" property="timestamp"/></td>
</tr>
<tr>
<td><b><struts:message key="showmessage.subject"/></b></td>
<td><h2><struts:htmlProperty name="message" property="subject"/></h2></td>
</tr>
</table>
<p/>
<struts:htmlProperty name="message" property="body"/>
</body>
