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.

<%@ 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>

</head> 
...
<td class="tdLabel">
<label for="widget_1291193434" class="label">Format (dd-MMM-yyyy):
</label></td> 
<td>
<div dojoType="struts:StrutsDatePicker"    id="widget_1291193434"

<%@ 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>

displayFormat="dd-MMM-yyyy" value="%{'today'}"/>
 
<s:submit value="submit" name="submit" />
 
</s:form>
 
</body>
</html>
