Re: Question about threads inside wicket pages
I'm not 100% sure, but I'm pretty sure that it would depend on your
servlet container more than Wicket. The threads for handling requests
are spun up by the servlet container before Wicket is ever handed the
request. And typically these threads are pooled - so it wouldn't be
*destroyed*. But you'll definitely need to do some testing on it to
be sure.

Right - the session, etc, is available via a ThreadLocal. So, it's
not available in a new thread.

Hi Jeremy,
I tried to call "Page.info()" inside the new thread created by
axis2client , then it gives the message :
"EXCEPTION :you can only locate or create sessions in the context
of a request cycle"
I guess,this means I must change the page data inside the same thread right?
Thanks in advance,
umanga
