Having trouble converting Spring time field on my JSP

Question

I'm using Spring 3.1.1.RELEASE. I have a model with the following attribute

@DateTimeFormat(pattern = "h:mm:ss a")
private java.util.Date meetingTime;

On my JSP, I have

                        <form:select path="meetingTime">
                            <form:option value="8:00 AM" name="8:00 AM" />
                        </form:select>

However, whenever I access my JSP I get the following error. Any ideas why its having trouble with the "AM/PM" portion of the time?

Answer 1

Try to use attribute "label": http://static.springsource.org/spring/docs/2.0.x/reference/spring-form.tld.html#spring-form.tld.option And note that you have time format: @DateTimeFormat(pattern = "h:mm:ss a") so use "8:00:00 AM" instead of "8:00 AM":

<form:select path="meetingTime">
   <form:option value="8:00:00 AM" label="8:00 AM" />
</form:select>

Answer 2

Try this:

                     <form:select path="meetingTime">
                        <form:option value="8:00 AM">8:00 AM</form:option>
                     </form:select>

"8:00 AM" is not the name of the option; it is the value and the text you wish to display.

Also, I believe the format specification for "8:00 a" is "h:mm a", not "h:mm:ss a".
