Fwiw, time invested in XML parsing would pay dividends.
Crimson/Xerces ain't nothing to write home about and they seem to
have the lions share of deployments in Java-land.
"The main point here is there is almost an order of magnitude
between straightforward Web services using XML encoding and an
implementation that takes care of binary encoding," - Eduardo.
Find a customer and imagine which you think they want to hear- "yes
its slower but it'll be up in 12 weeks, cheap and cheerful, and
anybody in oppers can read what's coming in off the wire", or "yes
it blazes but it'll take six months cost more, and no, oppers won't
be able to understand anything". Yes I do draw a direct correlation
with text wire formats over internet protocols with cost-effective
high relevancy integrations shipped earlier. Call me biased, but I
honestly don't know how anything got done at all in middleware
before XML and HTTP came along.
If there are plenty of customers who are deeply concerned about
performance then maybe this work has value, but I still think
optimizing the parsers is a better strategy, and even if you proved
it wasn't, I think I'd look for a briefer text format first
(xml2rnc for example), before I'd get into binary codecs.
Just as long as they don't start proposing fast HTTP or fast TCP :)
