Servlet UnavailableException: no class in holder when launching berth

Can someone tell me what this exception throws when the berth server starts. I am using berth 9.2.2

javax.servlet.UnavailableException: class is not supported

Web.xml contains

<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<servlet>
    <servlet-name>com.test.api.TestApiApplication</servlet-name>
</servlet>
<servlet-mapping>
    <servlet-name>com.test.api.TestApiApplication</servlet-name>
    <url-pattern>/v1/*</url-pattern>
</servlet-mapping>
</web-app>

TestApiApplication.java extends the application

public class TestApiApplication extends Application {

 public TestApiApplication() {
 }

@Override
 public Set<Class<?>> getClasses() {
    Set<Class<?>> s = new HashSet<Class<?>>();
    s.add(TestResource.class);
    return s;
 } 
}

A minimized version of my pom.xml:

<properties>
    <jersey.version>2.11</jersey.version>
    <spring.framework.version>4.0.6.RELEASE</spring.framework.version>
    <jaxrs.version>2.0</jaxrs.version>

You need to know how Jetty starts in yours yjava.servlet.container.jetty.JettyDaemonin order to respond with more depth.

If you want automatic posting in Jersey using the Servlet 3.0 technique described org.glassfish.jersey.servlet.init.JerseyServletContainerInitializer, then the class JettyDaemonwill have to include various annotation scan configurations for Jetty.
