Subject Large Scale Deploymenet on Tomcat ?
Date Tue, 28 Oct 2003 03:13:42 GMT


Hi !
Are there any success stories of deploying a large scale application
(10000+ 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...

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.
