Fedora RESTful HTTP API uses the open source Jersey RESTful Web Services framework that provides support for JAX-RS APIs and serves as a JAX-RS (JSR 311 & JSR 339) Reference Implementation. The jersey servlet dispatcher is configured in web.xml as follows:

<servlet>
	<servlet-name>jersey-servlet</servlet-name>
	<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
	<init-param>
		<param-name>com.sun.jersey.config.property.packages</param-name>
		<param-value>org.fcrepo</param-value>
