I deployed a web service and that went fine, but when I try to call it, I get a
reported NullPointerException. Can anyone give me any hints on what is going
on here? I don't believe my implementation of the service is even getting
called since I am printing to system.out as soon as that method gets called and
that never gets printed. Seems to be somewhere in the guts of Axis and/or the
JDK itself. Here's the stack trace from the server...
