Ah, sorry.  I read your email too quickly.  You are putting a
FieldMethodizer that is wrapping ApplicationConstants and want the
FieldMethodizer to proxy the methods as well as the fields.
Unfortunately, that's just not going to happen.  Too much work for too
little payoff, when there is an easy workaround.  Jian is right, you
will have to put an instance in to get at the methods.  Of course, you
won't be able to get at the constants from that instance.  So, you'll
have to put in both a normal instance and a FieldMethodizer instance.
Sorry.  In Velocity 1.6+, you could just put the
ApplicationConstants.class in to get access to the methods, but it
still wouldn't give you the fields.  So, either put both a
$ApplicationConstants  (the FieldMethodizer) and $ApplicationMethods
(the instance) in the context or else implement a public static Object
get(String fieldName) method in your ApplicationConstants class that
gives access to fields that way (which would let you get the fields
from the instance too).
