I am already using Guice for regular DI in my application, and wants it to handle the servlets as well. The relevant classes are given below.The setup still works fine with my regular DI, but once I add a serving rule in GuiceServletModule, I get the attached error/stacktrace on startup (using Jetty).
I get the same message if I set it up as suggested on http://code.google.com/p/google-guice/wiki/Servlets as well. I cannot manage to find any useful information about this error. Is there anybody who understands why this fails? *Error on startup:* 2012-05-16 15:46:31.535:WARN:oejw.WebAppContext:Failed startup of context o.m.j.p.JettyWebAppContext{...},file:...
