Question

I’ve been facing a critical issue from past one week on jetty web application deployment can any one please assist me where I’m doing the wrong stuff?

Description:

I’m building a Spring Boot (version:2.7.8) web application using JDK 17 as per client requirement.
In order to deploy the application, I’m using Jetty server with jetty-maven-plugin artifact (version 11.0.21)
I’ve gone through the below documentation pages to configure jetty-web.xml

https://jetty.org/docs/jetty/11/operations-guide/deploy/index.html

https://jetty.org/docs/jetty/11/programming-guide/maven-jetty/jetty-maven-plugin.html#jetty-run-goal

Now when I’m starting jetty server using clean install and jetty:run from my IDE, the server goes up but it’s not detecting any WebApplicationInitializers on class path and due to this Spring Boot application is not getting initialized.

Logs:

I tried to start spring boot application by changing different jetty version compatible with JDK 17 also added web.xml to manually provide the listener class, but application initialization is not happening. I would like to initiate spring boot application by triggering jetty server.

 <listener>
     <listener-class>org.springframework.web.context.WebApplicationContext</listener-class>
</listener>
