Well I've only got to the point of writing my first simple client/server
application with XML. By pure conincidence I'd managed to get _something_
working just before I saw your email so thought I'd chip in. It's a way of
doing it for me with simple client/server applications but I've yet to come
across HTTP POST and don't know of any implication here. Basically I'm
saying don't listen to the newbie too much cos I'm groping in the dark a bit

I'm curious to know if the solution I've found for my client/server
applications is wrong or is just wrong in the context for John. I was happy
to get it working but I'd be pleased to know if there is a better way of
achieving the same thing.
A previous attempt on my own solution had me sending a character count
before the document and doing more like the FAQ. I modified this when
someone pointed out that I only know the character count because my example
deals with disk files. If I had been sending the stream out from an
XMLOuputter in the client then how would I know up front how many characters
would be in that stream. The FAQ requires a known array size, I simply
modified this to use a string instead.
I couldn't close the output stream from the client because this closed the
socket. The server couldn't then respond back to the client with any results
it had generated.
Should I actually be layering another level of technology on top of what I
have here (HTTP POST?) to help me handle this?
As I've said before I'm pretty new to the technologies here. Taught myself
sockets from Bruce Eckels "Thinking in Java" and learnt how to read XML from
Jason & Bretts 2 articles on JavaWorld. I'm just at the bottom of the
ladder. Where would you suggest I go from here (articles/books) to get an
understanding of more complex XML comms?
I hope someone has the patience to set me straight.
