A word of caution. I am not sure that every version of Tomcat behaves that well. JBoss (based on Tomcat for the web serving portion) had problems with the isolation issue in several of its older versions (roughly around the time of Tomcat 5.0) and claimed that its problems were inherited from Tomcat. As far as I know, this kind of problems do not exist in Tomcat 5.5.
So, I would suggest testing to make sure you get no surprises. Forza Azzurri!!! bruno Bruno Melloni Director of Software Architecture Akuratus Corporation 1333 N.

This is because of Tomcat's default parent-last classloading behavior (recommended by the servlet spec). If you had parent-first classloading behavior, which is usually the default in most larger application servers, then you would have a problem.
