Do you mean create an object with a formatDate(String s, Date d) method,
and put this in the context as "tool".

However... I think velocity would evaluate $person.dob to a String first then call the method, thus
trying to call.

formatDate(java.lang.String, java.lang.String)
instead of
formatDate(java.lang.String, java.util.Date)

i.e. the second argument being the result of a java.util.Date.toString()
the equivalent of.

formatDate("MM/YY/DD", "Thu Jan 10 15:13:53 GMT 2002")

 "Everything coming to and from a reference is treated as a String object. If
 there is an object that represents $foo (such as an Integer object), then
 Velocity will call its .toString() method to resolve the object into a
 String."

that's what he means.  a good example of such a tool is at
http://cvs.apache.org/viewcvs/jakarta-commons-sandbox/rupert/src/java/org/ap
ache/commons/rupert/nathan/DateTool.java

no.  if your method dob()  in the $person object returns a Date,   then
velocity will pass the Date object to the method.   toString() is only
called when $person.dob is rendered.   if you pass it off to another method
before that, (e.g. $datetool.format("MM/DD/YYYY", $person.dob) )  then
velocity will try to find a format(String, Date)  method in $datetool.
