Hi,
You have to have a wap gateway that supports http sessions.
new versions of waplite support this.. (i'm guessing most gateways do)
if yours supports them, the HttpSession object (via session cookies) will
work fine.
Just use it as if the client is a web browser.
if not, you'll have to use url rewriting. I think the servlet api has direct
support for this, saving you alot of effort.
Use cookies if you can
