ok... How do I create one of these? I've downloaded you sample custom fields, and I've been trying for days to get a date time one. The date time selector from dynarch is a great little plugin, but for the life of me, I can't seem to get all the pieces of the puzzle to fit.

I have a custom field (based on the existing datetime field) that calls a new js function: show_calendar3 (which I created in date_picker.jsp). I am trying to get this new function to call a new jsp file CalendarTime which I can change the settings of the calendar component to include time, and format the string properly...

However, I am stuck with this error: HTTP Status 404 - Could not execute action [CalendarTime]:Action 'popups.CalendarTime' not found or could not be initialized: java.lang.ClassNotFoundException: popups.CalendarTime<...

I added the new action in actions.xml ( located in atlassian-jira\WEB-INF\classes )

<action name="popups.CalendarTime" alias="CalendarTime">
<view name="input">/secure/popups/calendartime.jsp</view>
<view name="success">/secure/popups/calendartime.jsp</view>
</action>

What else am I missing? Or, am I even in the right ballpark on how to do this?
