Struts 2 - DateTimePicker

I'm trying to implement the 'easy to use' datetimepicker (or datepicker) for a Struts 2 application based on this example and I'm getting the following error when I use the tag:

org.apache.jasper.JasperException: /MyApp.jsp(21,1) No tag "datetimepicker" defined in tag library imported with prefix "s"

I opened up the struts-tags.tld library for 2.1.6 and I don't see the tag defined. I'm guessing I'm missing a library but I can't tell which one.

I think I found the solution... I added the "struts2-dojo-plugin-2.1.6.jar" to my class-path and I added a second tag library:

<%@taglib prefix="d" uri="/struts-dojo-tags"%>

I must have 'missed' the documentation that covered these steps.

The S2.1 series release notes discuss the move to a Dojo tag plugin and the Ajax tag documentation includes the same information. As has been noted by others here on JavaRanch, RoseIndia isn't always your best bet for reliable, current information.

RoseIndia seems to come up with a lot of examples in google. Either way I'm still having trouble with the datetimepicker. The code compiles and runs, but it doesn't do much, as in, I see "Enter Date:" but that's about it. What other config do I need to add/install to make it work?

Number of hits != useful.

Do you have the <sx:head/> tag in your pages <head> section? (Also in the S2 docs.)

Ah, that did it. I saw an empty tag when the include ajax theme was taken out, and just 'assumed' it wasn't do anything anymore. My bad.
