How do I programmatically configure Jetty that I can use Servlet Annotations?

If you doing just servlets with jetty, this article could be interesting for you.

I show you how I did it. Here comes the configuration:

...
server = new Server(port);
server.addBean(LOG);
WebAppContext webAppContext = new WebAppContext();
webAppContext.setContextPath("/");
String webxmlLocation = JettyServer.class.getResource("/webapp/WEB-INF/web.xml").toString();
webAppContext.setDescriptor(webxmlLocation);
String resLocation = JettyServer.class.getResource("/webapp").toString();
webAppContext.setResourceBase(resLocation); webAppContext.setParentLoaderPriority(true);
webAppContext.getMetaData().addContainerResource(Resource.newResource(
new File(JettyServer.class.getProtectionDomain().getCodeSource().getLocation().getPath())));
webAppContext.setConfigurations(new Configuration[] { new WebInfConfiguration(), new WebXmlConfiguration(),
new MetaInfConfiguration(), new FragmentConfiguration(), new EnvConfiguration(), new PlusConfiguration(),
new AnnotationConfiguration(), new JettyWebXmlConfiguration() });
server.setHandler(webAppContext);
server.start();
...

And I defined the following dependencies in build.gradle.

...
def jettyVersion = '9.4.7.v20170914'
dependencies {
providedCompile 'javax.servlet:javax.servlet-api:3.1.0'
compile group: 'org.eclipse.jetty', name: 'jetty-servlet', version: jettyVersion
compile group: 'org.eclipse.jetty', name: 'jetty-webapp', version: jettyVersion
compile group: 'org.eclipse.jetty', name: 'jetty-annotations', version: jettyVersion
compile group: 'org.eclipse.jetty', name: 'jetty-plus', version: jettyVersion
compile group: 'org.eclipse.jetty', name: 'apache-jsp', version: jettyVersion
compile group: 'org.ow2.asm', name: 'asm', version: '5.1'
compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.25'
compile group: 'org.slf4j', name: 'slf4j-log4j12', version: '1.7.25'
compile group: 'log4j', name: 'log4j', version: '1.2.17'
...
}
...

That’s all. Hope this helps!
