Subject: Large Scale Deploymenet on Tomcat ?
Hi !
Are there any success stories of deploying a large scale application
(1+ users ) on tomcat+jboss out there ? Really need to convince the
top
bosses down here to give it a chance :)

Agreed. One word of caution...

I've had to do this before when credit card processing was being done. A
double-click can result in the credit card being charged twice, so
you've really got to avoid it.
We actually synchronized on the session for the duration of the
processing, and then set a flag in the session once the processing was
done. Any subsequent attempts would be flagged as duplicates and you'd
just get a results screen.
You aren't guaranteed to have the same HttpSession object for every
request -- HttpSession is an interface which is implemented internally
and wrapped by a facade. Synchronizing on the actual object you get from
req.getSession() can potentially leave you synchronizing on totally
different objects.
