Makes perfect sense to me.
The servlet times out on the DB connection, which may take up to a
minute or so
If so, how?
On BEGIN events I am storing the HttpServletRequest, HttpServletResponse,
and the ServletContext associated with the request.

No, Tomcat renames the classes in the jar to avoid collisions with any webapps

Sorry - I was going to put that in and just forgot. Old age strikes again.
It is 6.0.20.
Can I simply delete the tomcat version of dbcp (jar file) and drop in

You are all correct.
So, I wasn't necessarily looking for a code solution. The system works

It still seems like a simple issue to me.
Split your initialization of A into A1 and A2.
A2 is no longer part of immediate initialization for A.
Put your Scheduler launches, with their Data retrieve components, into
A2.
When A is started, it will only run A1.
When B is started, at the end of it

Cross-context forwarding
True, I did ask for a reference, for the specific issue of http requests out
of a webapp to another webapp in the same container "during initialization,"
causing a halt condition.
