How can I populate a date object for a struts2 action in a jsp form?

I know how to populate object with simple types (int, String) but how can I do this for a date value???

My class (called User) has an attribute called date of type java.util.Calendar, is there any way to populate this field automatically on a html/jsp form?

My form:

 Date: <input type="text" name=开发者_运维问答"user.date">

dates - uses the SHORT format for the Locale associated with the current request

struts2.0.14

Also take a look at the custom converter example

try and implement a custom converter

public class MyConverter extends StrutsTypeConverter {
    public Object convertFromString(Map context, String[] values, Class toClass) {
       SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
       Date date = sdf.parse(values[0]);
       //do some validation on class and other stuff
    }

    public String convertToString(Map context, Object o) {
       SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
       return sdf.format(o);
    }
 }

then register it with

user.date = com.xyz.MyConverter

in a properties file MyAction-conversion.properties

<s:date name="user.date" format="MM/dd/yyyy" />

here the user.date is of Date type not checked with Calendar. please check
