Hi Francois, "I have looked at the spec and I haven't seen something saying that the CDI event couldn't be received if the observer is packaged in war itself embedded in an ear."
specifications work the opposite way. If you didnt find it then it is not specified and up to the implementation. Said otherwise wildfly is not right but is not wrong and same for tomee. IIRC TomEE propagates events from webapp to ear-libs part but the opposite is avoided - we are aligned on classloaders to avoid to leak informations. The EJB should use the ear-lib classloader by spec so it would be weird to leak the event in the webapp by design. I agree you can say it is under a request so we could find it - technically it is true and easy - but then take into account @Asynchronous, concurrency-utilities and simply hierarchy model and reusing the request is really no more obvious - personally I fight to not reuse it to keep the application understandable. I know wildfly has a "flat" mode but from experience we chose the less broken solution to stay friendly with deltaspike and codi to cite a few. ear and CDI is highly under specified and portability there needs some carefulness.
