import com.opensymphony.xwork2.ActionSupport;
 
public class DateTagAction extends ActionSupport{
 
	public Date customDate;
 
	public String execute() {
 
		Calendar cal = Calendar.getInstance();
		//set date to january 31, 2010
		cal.set(2010, 0, 31);
		Date newDate = cal.getTime();
 
		setCustomDate(newDate);
 
		return SUCCESS;
 
	}
 
	public Date getCustomDate() {
		return customDate;
	}
 
	public void setCustomDate(Date customDate) {
		this.customDate = customDate;
	}
 
}

    Hy Mkyong,
    I have really learnt a lot about struts 2 from your tutorials. But I’m having some trouble with taking date input in my POC application. Hope you can find some time to help me out.

    My problem:
    I’m using the modeldriven method, one of the feild is a date. when I run the application from IE it takes almost any date format (eg dd/MM/yyyy dd-MMM-yyyy dd.MM.yy)
    But when I run the same application from firefox (portable version) only MM/dd/yyyy works (any other format give error message “Invalid value enter for xxx”). I’m guessing this is bcoz its a portable version and locale must be set to en-us.

    Now, is there some setting by which I can set the locale or date format for my application. I’ve tried struts.date.format in the properties, but it only affects the tag and not the input format.

    What would be the best way to fix my date input format irrespective of locale? eg en-uk

    if you can give a sample code then that would be great or can you atleast point me in the right direction.

    Thanks,
    Rushi
