well, this is better than restart the context by yourself each time.

Hm, but this isn't really bad in my opinion, is it?

i think this is no problem as long as you have no "backoffice" part in 
your online webapp. Then the session is destroyed but the user will not 
see this.

Another option could be the usage of JBoss. Here the Tomcat destroys no 
sessions if you add a lib as far as i know. Next possibility could be to 
configure tomcat in this way that the sessions are stored in a database 
instead of the ram. So you are able to manage the session handling at 
reload cycle by yourself.
