I want to use the tag weekdays in my jsp. I copy the code as the following: Select a Week Day <select name="weekday"> <dt:weekdays id="day"> <option value="<jsp:getProperty name="day" property="dayOfWeek"/>"> <jsp:getProperty name="day" property="weekday"/> </dt:weekdays> </select> then I display my jsp. In the select tag, ??? is displayed. Does this mean i have to usebean? I wonder what property it should have? how to set the property?
