I've been working on this part of xt myself, and I sort of hope that
thinking through your issue will help me think about mine.
There are two troubles here...a bit with the Date itself, mostly with the
conversion. Clark's very brief documentation, in "xt.htm", says that
xt numbers are traded for Java Doubles, and the IllegalArgumentException
message you're getting from his ExtensionHandlerImpl.java comes from
trying to use Doubles to construct a Date. So far as I know, you can
only do this by subclassing Date like so:
-----------------------------------------------------------------
package MyNa.jspUtil; // if you want it in a package
public class DDate extends java.util.Date{
public DDate(Double y, Double m, Double d){
super(y.intValue(),m.intValue(),d.intValue());
}
}
-----------------------------------------------------------------
I then put the package in a jar (it has to be in a jar (?)) like so:
javac MyNa/jspUtil/DDate.java
jar -uf MyNajsp.jar MyNa/jspUtil/DDate.class
and make sure the jar is on the class path or in the right lib/ext
directory.
Then I can call it, with other examples, like so (some header
stuff not needed but I'm editting an existing example); first I
call on the straight date:new(), then on System.getProperties(),
then on DDate(100,1,1) (That's Feb 1, 2000, and as you'll see
below it shows as "Tue Feb 01 00:00:00 EST 2000"; Date is a
deprecated class, after all, and DDate(2000,1,1) will show Feb 1,
3900). And then, just for the fun of it, I call on a "vdoc" class
which generates a NodeIterator as output from a jdbc ResultSet.

The mechanism is very nice...as I was moaning yesterday, I can't
get it to generate non-html output and still set the contentType
so I can't see it on my simulated WAP phone, but the basic
mechanism is very nice.
