Thanks Howard, I've altered the 'contribution element to the following: configuration-id="tapestry.init.ApplicationSpecificationInitializer"> id="zzz" object="service:application.zzz"/> But now I get the error message: org.apache.hivemind.ApplicationRuntimeException: Error at context:/WEB-INF/hivemodule.xml, line 29, column 85: Module application has contributed to unknown configuration point tapestry.init.ApplicationSpecificationInitializer. The contribution has been ignored. It seems I don't have visibility of the tapestry configuration points. How I declare/reference the configuration point? Paul.
