WebApplicationInitializer is not getting detected

[Burt Repine]

Hello,

I'm trying to port our application from WildFly 10.1 to WildFly 20 and our WebApplicationInitializers are not getting detected?
Is there additional configuration that needs to be done?

Googling the issue did not seem to turn up anything.

On 10 I can view the following console logging but nothing on 20:

INFO  [io.undertow.servlet] (ServerService Thread Pool -- 58) No Spring WebApplicationInitializer types detected on classpath
INFO  [io.undertow.servlet] (ServerService Thread Pool -- 64) 1 Spring WebApplicationInitializers detected on classpath

Thanks for the help!

Is Spring included in your deployment or is it installed as a module?

[Burt Repine]

It's installed as a module

[James Perkins]

I would assume the deployment would fail if the module isn't being seen. I don't really know how Spring works, but I guess I'd make sure that the modules match.

The deployment is successful. Not sure what you mean by ' make sure that the modules match'?

Do you have a sample project that we could check?

Unfortunately not. That would be quite a bit of effort

There are some examples related with `resteasy-spring` that may have
some reference values:

I was finally able to get this working by making the following jboss-deployment-structure.xml change:

before:

<module name="our.module.that.contains.spring" services="export" slot="1.0"/>

after:

<module name="our.module.that.contains.spring" services="import" slot="1.0"/>

Don't know why 'services' was set to 'export' in the first place (before my time) or what the significance is by switching it to 'import'.

By significance I mean why did it work in WildFly 10 but not in WildFly 20.

The documentation around this is pretty sparse.
Can anyone help/explain?

Thanks,

Burt
