Weld can be used to add support for CDI (Contexts and Dependency Injection) to Servlets, Listeners and Filters. It is easily configured with Jetty 9.
The easiest way to configure weld is within the jetty distribution itself:
Ensure your WEB-INF/web.xml contains the following:
<listener>
<listener-class>org.jboss.weld.environment.servlet.Listener</listener-class>
</listener>
<resource-env-ref>
<description>Object factory for the CDI Bean Manager</description>
<resource-env-ref-name>BeanManager</resource-env-ref-name>
<resource-env-ref-type>javax.enterprise.inject.spi.BeanManager</resource-env-ref-type>
</resource-env-ref>That should be it so when you start up your jetty distribution with the webapp you should see output similar to the following (providing your logging is the default configuration):
