Hello
Thanks for the logs and jetty.xml - it helped.
So ChatGPT suggested you to _replace_ the Pax Web handler with your own -
that's how you broke the connection between Jetty and Pax Web.
Pax Web sets a "handler collection" hander as the Server's handler and you
can't replace it - you can _add_ another handler. You can do it
programmatically as I showed with JettyHandlerServceInterationTest.java,
but you can do it declaratively too with jetty.xml. Instead of <Set
name="handler"> do this:
<Get name="handler">
<Call name="addHandler">
<Arg>
<New class="org.eclipse.jetty.server.handler.ContextHandler">
<Set name="contextPath">/static-content</Set>
<Set name="handler">
<New class="org.eclipse.jetty.server.handler.ResourceHandler">
<Set name="resourceBase">target/logs</Set>
<Set name="directoriesListed">true</Set>
</New>
</Set>
</New>
</Arg>
</Call>
</Get>
kind regards
