I am using Apache Continuum 1.3.4 (Beta) running under Tomcat 5.5.28 on linux.

I see the following WARNING in my continuum.log on startup (I don't
have a shared.xml - there is no documentation to create this xml
file). My continuum instance seems pretty normal, but I just wanted to
forward this info on just in case there really is something that I
should do about it.
