Re: Stateful Web Services...

hi Cristovao,

i don't know which definition you are refering to, but i do not think that 

such a restriction would be useful.

Sure, HTTP is a stateless protocol (maybe that's what you are referring 
to),
but you can use things like session tokens to group multiple stateless
calls into (stateful) sessions. 

e.g.:
1. login(username, pwd) => return sessoin token sid 
2. listItems(sid)
3. addToCart(sid, someItem)
3. checkout(sid)

yes, this is already possible

check out Apache Axis (http://ws.apache.org/axis/index.html) and/or
WS-enabled application servers like JBoss, etc.
