Hi philippe,
When I read this question, I cant help feeling there is a conceptual issue 
It is possible to pack servlets into libs and use them in TC, and the 
web.xml in the main project will govern all the servlets?
Its possible to make TC reload libs, but its better to use late binding, ie 
once TC has loaded libs and is running, replacing the jar
will not change the TC's existing lib, which is actually just the way java 
itself works?

I think you'd be better off describing to the guys, "why" you doing what you 
doing... and then let the gurus tell you how they would do it.
There are many ways in TC, but some ways are just not right ;)

Soon as you say deploy Jars... not Wars, that raises issues, if you mean 
wars and you just need one to start before the other
that is also possible from the XML setting... please explain more?
