Include Tag (Data Tag) Example
In this section, we are going to describe the include
tag. The include tag is a generic tag that is used to include a servlet's
output (result of servlet or a JSP page) to the current page.
Add the following code snippet into the struts.xml
file.
struts.xml
<action name="includeTag" class="net.roseindia.includeTag">
<result name="success">/pages/genericTags/includeTag.jsp</result>
</action> |
Create an action class as shown below:
includeTag.java
package net.roseindia;
import com.opensymphony.xwork2.ActionSupport;
import java.util.*;
public class includeTag extends ActionSupport {
private Date myBirthday;
public String execute() throws Exception{
setMyBirthday(new Date("Jan 12, 1984 11:21:30 AM"));
return SUCCESS;
}
public Date getMyBirthday(){
return myBirthday;
}
}
|
Create a simple jsp (myBirthday.jsp) that we
want to include in our main jsp page ie..includeTag.jsp.
myBirthday.jsp
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Include Tag (Data Tag) Example!</title>
</head>
<body>
<b><font color="#000080">My Birth Day (Date Format)</font></b>
<table border="1" width="35%" bgcolor="ffffcc">
<tr>
<td width="50%"><b><font color="#000080">Date Format</font></b></td>
<td width="50%"><b><font color="#000080">Date</font></b></td>
</tr>
<tr>
<td width="50%">Day/Month/Year</td>
<td width="50%"><s:date name="myBirthday" format="dd/MM/yyyy" /></td>
</tr>
<tr>
<td width="50%">Month/Day/Year</td>
<td width="50%"><s:date name="myBirthday" format="MM/dd/yyyy" /></td>
</tr>
<tr>
<td width="50%">Month/Day/Year</td>
<td width="50%"><s:date name="myBirthday" format="MM/dd/yy" /></td>
</tr>
<tr>
<td width="50%">Month/Day/Year Hour<B>:</B>Minute</td>
<td width="50%"><s:date name="myBirthday" format="MM/dd/yy hh:mm" /></td>
</tr>
<tr>
<td width="50%">Month/Day/Year Hour<B>:</B>Minute<B>:</B>Second</td>
<td width="50%"><s:date name="myBirthday" format="MM/dd/yy hh:mm:ss" /></td>
</tr>
<tr>
<td width="50%">Nice Date (Current Date & Time)</td>
<td width="50%"><s:date name="myBirthday" nice="false" /></td>
</tr>
</table>
</body>
</html>
|
Now create a jsp page using <s:include> tag
as shown in the includeTag.jsp
page. The <s:include value="myBirthday.jsp" />
tag includes another jsp using the value parameter
includeTag.jsp
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Include Tag Example!</title>
</head>
<body>
<h1><span style="background-color: #FFFFcc">Include Tag (Data Tags)
Example!</span></h1>
<s:include value="myBirthday.jsp" />
</body>
</html>

Output of the includeTag.jsp :
