It is not an ActiveX control. If it were an ActiveX control, then it would be
easier to deal with but harder to port to different environment. ActiveX can
only work on Microsoft Windows family.
Let me give you an example of what I'm going to do.
If you do online banking, you can set up bill payments on specific dates.
Usually, the online banking web interface provides a calendar for your select
the date on which the payment will occur.
Typically, the default date is today and, if you change the month or the year,
the calendar itself refreshes itself by displaying the days in the month of
the year you have selected.
Obviously, when you select a new month or a new year, the html page that
accomodates the calendar control should post back to the server and render the
page again with the correct days displayed.

Sorry for the confusion.
By "pure HTML controls", I meant those <html:form>, <html:text> tags
introduced in Struts after you declare them in the web.xml.
<taglib>
<taglib-uri>/tags/struts-html.tld</taglib-uri>
<taglib-location>/WEB-INF/struts-html.tld</taglib-location>
</taglib>

Yes, the page should change by posting back to itself and display respective
days of the month you've selected.
I want to use this control in future projects. For, this control should only
be responsible for displaying a calendar.
So, in the JSP page, I want to simply to a calendar tag like:
<html>
<body>
<form>
<calendar />
</form>
</body>
</html>
If necessary, we can add necessar attributes to the <calendar> tag. Once the
page is submitted to the server, I can catch the date selected via the
calendar control and do something accordingly.
Just like a textbox control on an HTML page. You enter some value in the
textbox and submit it to the server for processing. In my case, I'm just
finding out a way to submit the selected date of the calendar to the server
and have the information processed.
Hope this makes things clear. :-)
Thanks!
Peter
