Fat jar works for embedded Jetty and Tomcat but not for Undertow

[bjorntj]

I am trying to create a executable fat jar instead of war files for my Spring Boot projects , where I use JSF and Primefaces.
My test project works fine using either Jetty or Tomcat but Undertow complains about not finding the resources for the Primefaces theme I use..

I have included a test project...
undertow_test.tar.zip

btw, this test project works when running as java -jar jarfile but not when I run it as gradle bootRun, any pointers what I need to do to make it work using gradle bootRun?

Thanks for the sample, but it's left me a bit confused. It appears to be using Jetty but you said the problem was with Undertow. I get a failure with bootRun when I try to access http://localhost:8080. The index appears to work fine with java -jar. If I switch to Undertow I see the same failure as Jetty with bootRun and it doesn't work with java -jar either (but with a different failure to the one seen with bootRun).

Can you please clarify the problem that you're reporting? I don't want to waste time diagnosing something else.

Yes, forgot to change the dependency back to undertow, so yes, my problem is when using undertow and using java -jar. bootRun does not work on either and as I mention in my comment above, I am not sure how to make this project wok using bootRun, but perhaps you have some ideas?
And yes, the error is different when using bootRun. When using bootRun, is seems that it does not find the static resources in the web_resources jar file at all.

There are two things going on here. Firstly, your resources are in the wrong place. They're in src/main/resources/META-INF/resources/resources but they should be in src/main/resources/META-INF/resources. Secondly, things don't work with bootRun due to #8525 which is fixed in 1.4.6 and 1.5.3 snapshots.

If I move your resources to the right location and use 1.5.3.BUILD-SNAPSHOT things work fine with Undertow using both bootRun and java -jar.

ok, the placement is just copied from the example project from Primefaces using their theme but I guess I do not need to follow this...
Thx... :)
