That looks like the one where promoted services are ignored so you need to move your <service> with the WS binding to be inside the <component>. See this thread: http://apache.markmail.org/search/?q=%22[2.x]+Calculating+Endpoints+to+promoted+services%22+order%3Adate-forward I note that we still haven't added the message. Thanks for the feedback on the poor error messages and having to "include everything", we are continually improving this and I'd hope its much better by 2.0 ...ant
