Jetty 11 does not find Jakarta servlets

[Kjell]

Hi,

I am upgrading from Java 8 to Java 17, using maven and Jetty 11.0.18. Everything compiles and the server starts, but I don't get the welcome file and for all servlets I get a 404. This is my Main, which is called during startup. The servlets are in the jar. What could be the problem?

Here is my Main

  public static void main(String[] args) throws Exception {

    // Create a server that listens on port 8080.

    int port = Integer.parseInt(System.getenv().getOrDefault("PORT", "8080"));

    String host = System.getenv("HOST");

    Server server;

    if (host != null)

    server = new Server(new InetSocketAddress("dev.domain.com", port));

    else

    server = new Server(port);

        WebAppContext context = new WebAppContext();

        //Resource base = Main.class.getClassLoader().getResource("./target");

        //context.setBaseResource(base);

        context.setContextPath("/");

        context.setWelcomeFiles(new String[]{"index.html"});

        context.setParentLoaderPriority(true);

        server.setHandler(context);

    // Load static content from inside the jar file.

    URL webAppDir =

        Main.class.getClassLoader().getResource("META-INF/resources");

    System.out.println("webAppDir " + webAppDir);

    // webAppContext.setResourceBase(webAppDir.toURI().toString());

    System.out.println("Configuration discovered? " + context.isConfigurationDiscovered());

    System.out.println("getBaseResource " + context.getBaseResource());

    String [] classes = context.getConfigurationClasses();

    for (int i = 0; i<classes.length; i++)

    System.out.println("getConfigurationClasses " + classes[i]);

    // server.setDumpAfterStart(true);

    server.start();

  }

The output:

webAppDir file:/C:/<rootdir>/target/classes/META-INF/resources
Configuration discovered? true
getBaseResource null
getConfigurationClasses org.eclipse.jetty.webapp.WebInfConfiguration
getConfigurationClasses org.eclipse.jetty.webapp.WebXmlConfiguration
getConfigurationClasses org.eclipse.jetty.webapp.MetaInfConfiguration
getConfigurationClasses org.eclipse.jetty.webapp.FragmentConfiguration
getConfigurationClasses org.eclipse.jetty.webapp.JndiConfiguration
getConfigurationClasses org.eclipse.jetty.webapp.WebAppConfiguration
getConfigurationClasses org.eclipse.jetty.plus.webapp.EnvConfiguration
getConfigurationClasses org.eclipse.jetty.plus.webapp.PlusConfiguration
getConfigurationClasses org.eclipse.jetty.annotations.AnnotationConfiguration
getConfigurationClasses org.eclipse.jetty.webapp.JettyWebXmlConfiguration

Also tried to se MAVEN_OPTS to

-Dorg.eclipse.jetty.annotations.AnnotationConfiguration.LEVEL=DEBUG

but no relevant output. 

setDumpAfterStart(true) didn't list any of my servlets, should it?

What am I missing?

Best,

Kjell

context.setResourceBase(webAppDir.toURI().toString());

solved the welcome file issue, but still no servlets. Is there a way to debug what AnnotationConfiguration actually does?
