It is likely that he has a custom Tomcat component (e.g. a custom Realm) that he also want visable to webapp code. With a little bit more work, it probably wouldn't be hard to stick to the TC 5.5 hierarchy (e.g. an interface and a class containing a ThreadLocal in common/lib, and the Realm implementing the interface and a Valve in server/lib to make the connections). However in its default configuration, TC 6 has a similar classloader hierachy to the one that you have (it uses restrictive SecurityManager restriction to protect TC classes, and says "don't care" if you're not using a SecurityManager). > Any advice is appreciated. > > Mark T.
