My guess is that it doesn't make any sense to accept requests from
clients before the services are actually available.

As I see it, you have several options:

* Run your webapps in different Tomcat instances, and start them up in
the order you prefer.

* Change your webapps so that they can communicate lazily with each
other instead of immediately upon deployment. This allows you to keep
the existing startup semantics but let your webapps communicate
appropriately.

* Modify Tomcat to start the connectors first and then the webapps.
Understand that you might get some 404s or other weird errors during
webapp deployment.

I'm sure it could have some side effects... what they are I couldn't
guess. Good advice in all environments: test, test, test.
