RE: EAR using Deltaspike
I sure didn’t. 😊 Vaadin CDI is in place. Maybe an article updated is needed, or a “Part 2”. I added exclusions in the UI pom.xml. And work perfectly. Thank you for your help, Ricardo De: Matti Tahvonen
RE: EAR using Deltaspike
That is it. As soon as I added them, it worked. The intent to play with EAR is to have a clear separation between business logic , domain objects and UI. But I will also play with the WAR packaging. Thank you for the advise. De: John D. Ament
Re: EAR using Deltaspike
I hope you are not literally following those instructions as they are rather
dated. As John said you are probably better of with plain war packaging these
days. If you are using Vaadin CDI ( and you should, even though the old wiki
instructions don't mention), I'd check there are no version collisions with
Deltaspike. Vaadin CDI depends on an older version, but you can most probably
exclude its dependencies and use a newer version.
I hope this helps,
Matti

Re: EAR using Deltaspike
Ok, I see you're packaging JARs. Is DeltaSpike packaged in your lib folder?
And I have to ask - do you need to use EAR packaging? Your whole
deployment structure is going to be orders of magnitude less complex by
packaging a WAR file, with your dependent JARs in it.
