[NOTE]
OSGi *requires* a `ServiceLoader` implementation for Jetty to function properly.
OSGi leverages http://aries.apache.org/modules/spi-fly.html[Apache Aries SPI Fly] for this functionality.
You can read more about OSGi and `ServiceLoader` http://blog.osgi.org/2013/02/javautilserviceloader-in-osgi.html[here.]

Even if your webapp itself does not not use annotations, you may need to deploy these jars because your webapp depends on a Jetty module or a 3rd party library that uses a http://docs.oracle.com/javaee/6/api/javax/servlet/ServletContainerInitializer.html[javax.servlet.ServletContainerInitializer].
This interface requires annotation support.
It is implemented by providers of code that extend the capabilities of the container.
An xample of this is the Jetty JSR356 Websocket implementation, although it is being used increasingly commonly in popular libraries like link:http://projects.spring.io/spring-framework/[Spring], link:https://jersey.java.net/[Jersey] and JSP containers.

To find `ServletContainerInitializers` on the classpath, Jetty uses the Java http://docs.oracle.com/javase/7/docs/api/java/util/ServiceLoader.html[`ServiceLoader`]
mechanism.
For this to function in OSGi, you will need an OSGi R5 compatible container, and have support for the http://blog.osgi.org/2013/02/javautilserviceloader-in-osgi.html[Service Loader Mediator].
Jetty has been tested with the http://aries.apache.org/modules/spi-fly.html[Aries SpiFly] module,which is the reference implementation of the Service Loader Mediator, and is listed in the jars above.
