Actually it's interesting you mentioned Jason Hunter because I found this
example in his excellent Java Selvet Programming book (p. 339). However it
seems that some of the stuff in there it just got old although all the
examples (if you exclude interservlet communication) ran without problems. I
think there's a new version of this book coming out this month.
I'll have a look at Java World.
Thanks again.
