!!!Answer!!!- From Technical Expert

Add <html:errors/> to your jsp page.

validate() : Used to validate properties after they have been populated; Called before FormBean is handed to Action. Returns a collection of ActionError as ActionErrors. Following is the method signature for the validate() method.

public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) {

ActionErrors errors = new ActionErrors();
if ( StringUtils.isNullOrEmpty(username) && StringUtils.isNullOrEmpty(password)){
                    errors.add(ActionErrors.GLOBAL_ERROR, new ActionError("error.usernamepassword.required"));
                }
return errors;
}

You have to add the error key from resource bundle.

error.usernamepassword.required : key from resource bundle properties file.

In the JSP , you have to add the below tag to display the error message from validate() method.
<html:errors />
