In Struts 2, the dojo ajax tag “<sx:datetimepicker>” will render a text box and append a calender icon behind, click on the calender icon will prompt a date time picker component.

To create a date time pick component, just ensure :
1. Download the struts2-dojo-plugin.jar library.
2. Include the “struts-dojo-tags” tag and output its header.

开始时把struts2-dojo-plugin.jar包导入到项目WEB-INF/libx下

<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>
<html>
<head>
<sx:head />
</head>

For example,

<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>
<html>
<head>
<sx:head />
</head>
<body>
<sx:datetimepicker name="date2" label="Format (dd-MMM-yyyy)" 
displayFormat="dd-MMM-yyyy" value="%{'2010-01-01'}"/>
...

Resulting the following HTML, few dojo and JavaScript libraries to create a date time pick component.

<html> 
<head> 
<script language="JavaScript" type="text/javascript"> 
    // Dojo configuration
    djConfig = {
        isDebug: false,
        bindEncoding: "UTF-8"
          ,baseRelativePath: "/Struts2Example/struts/dojo/"
          ,baseScriptUri: "/Struts2Example/struts/dojo/"
         ,parseWidgets : false
    };
</script> 
<script language="JavaScript" type="text/javascript"
        src="/Struts2Example/struts/dojo/struts_dojo.js"></script> 
 
<script language="JavaScript" type="text/javascript"
        src="/Struts2Example/struts/ajax/dojoRequire.js"></script> 
 
<link rel="stylesheet" href="/Struts2Example/struts/xhtml/styles.css" type="text/css"/> 
 
<script language="JavaScript" src="/Struts2Example/struts/utils.js" 
type="text/javascript"></script> 
 
<script language="JavaScript" src="/Struts2Example/struts/xhtml/validation.js" 
type="text/javascript"></script> 
 
<script language="JavaScript" src="/Struts2Example/struts/css_xhtml/validation.js" 
type="text/javascript"></script> 
</head> 
...
<td class="tdLabel">
<label for="widget_1291193434" class="label">Format (dd-MMM-yyyy):
</label></td> 
<td>
<div dojoType="struts:StrutsDatePicker"    id="widget_1291193434"    
value="2010-01-01"    name="date2"    inputName="dojo.date2"    
displayFormat="dd-MMM-yyyy"  saveFormat="rfc"></div> 
</td> 
</tr> 
<script language="JavaScript" type="text/javascript">
djConfig.searchIds.push("widget_1291193434");</script>

Struts 2 <S:datetimepicker> Example

A complete full example of the <s:datetimepicker> tag to generate a datetimepicker component, and show the use of OGNL and Java property to set the default date to the “datetimepicker” component.

1. Pom.Xml

Download the Struts 2 dojo dependency libraries.

pom.xml

//...
   <!-- Struts 2 -->
   <dependency>
      <groupId>org.apache.struts</groupId>
      <artifactId>struts2-core</artifactId>
      <version>2.1.8</version>
    </dependency>
 
    <!-- Struts 2 Dojo Ajax Tags -->
    <dependency>
      <groupId>org.apache.struts</groupId>
      <artifactId>struts2-dojo-plugin</artifactId>
      <version>2.1.8</version>
    </dependency>
//...

2. Action Class

Action class to store the selected date.

DateTimePickerAction.java

package com.mkyong.common.action;
 
import java.util.Date;
import com.opensymphony.xwork2.ActionSupport;
 
public class DateTimePickerAction extends ActionSupport{
 
	private Date date1;
	private Date date2;
	private Date date3;
 
	//return today date
	public Date getTodayDate(){
 
		return new Date();
	}
 
	//getter and setter methods
	public String execute() throws Exception{
 
		return SUCCESS;
	}
 
	public String display() {
		return NONE;
	}
 
}

3. Result Page

Render the date time picker component via “<s:datetimepicker>” tag, set the default date via Java property and OGNL.

The ‘ displayFormat‘ attribute is supported in many date patterns, read this article – Date Format Patterns.

Ensure you put the “struts-dojo-tags” tag and render it’s header <sx:head />

<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>
<html>
<head>
<sx:head />
</head>

datetimepicker.jsp

<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>
<html>
<head>
<sx:head />
</head>
 
<body>
<h1>Struts 2 datetimepicker example</h1>
 
<s:form action="resultAction" namespace="/" method="POST" >
 
<sx:datetimepicker name="date1" label="Format (dd-MMM-yyyy)" 
displayFormat="dd-MMM-yyyy" value="todayDate" />
 
<sx:datetimepicker name="date2" label="Format (dd-MMM-yyyy)" 
displayFormat="dd-MMM-yyyy" value="%{'2010-01-01'}"/>
 
<sx:datetimepicker name="date3" label="Format (dd-MMM-yyyy)" 
displayFormat="dd-MMM-yyyy" value="%{'today'}"/>
 
<s:submit value="submit" name="submit" />
 
</s:form>
 
</body>
</html>

result.jsp

<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
 
<body>
<h1>Struts 2 datetimepicker example</h1>
 
<h4>
   Date1 : <s:property value="date1"/> 
</h4> 
 
<h4>
   Date 2 : <s:property value="date2"/> 
</h4> 
 
<h4>
   Date 3 : <s:property value="date3"/> 
</h4>
