How about a ServletContextListener?

  http://docs.oracle.com/javaee/6/api/javax/servlet/ServletContextListener.html

or a LifecycleListener?

  https://tomcat.apache.org/tomcat-7.0-doc/config/listeners.html

Either one should allow you to configure your proxy settings before your 
applications start.
