<s:textfield id="txtDob" name="dateOfBirth" />
public class Person {
private Calendar dateOfBirth;

public void setDateOfBirth(Calendar dateOfBirth) {
this.dateOfBirth = dateOfBirth;

Instead of using s:textfield tag try using dojo ajax sx:datetimepicker tag. 而不是使用s：textfield标记尝试使用dojo ajax sx：datetimepicker标记。 Before using dojo tags add respective jars. 在使用dojo标签之前添加相应的jar。
<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ taglib prefix="sx" uri="/struts-dojo-tags"%>
<html>
<head>
<title>Example/title>
<s:head />
<sx:head />
</head>
<body>
<sx:datetimepicker name="dateOfBirth" label="Date Of Birth"
displayFormat="MM/dd/yyyy" />
</body>
</html>

This is because struts2 has a set of type convertors out of the box and struts2 only supports date conversion and it uses the SHORT format for the Locale associated with the current request. 这是因为struts2有一组开箱即用的类型转换器，struts2只支持日期转换，它使用与当前请求关联的Locale的SHORT格式。
You can create your custom type convertor and can tell struts2 to use that type convertor for Calendar object. 您可以创建自定义类型转换器，并可以告诉struts2将该类型转换器用于Calendar对象。 creating a custom type convertor is quite easy and straight forward.make use of StrutsTypeConverter class being provided by S2 for this purpose 创建自定义类型转换器非常简单直接。可以使用S2为此提供的StrutsTypeConverter类
public class MyConverter extends StrutsTypeConverter {
public Object convertFromString(Map context, String[] values, Class toClass) {
.....
}
public String convertToString(Map context, Object o) {
.....
}
}
