There could be a chicken/egg issue here in that the Jersey
SpringServlet gets access to the WebApplicationContext by doing:
private ConfigurableApplicationContext getDefaultContext() {
final WebApplicationContext springWebContext =
WebApplicationContextUtils
.getRequiredWebApplicationContext(getServletContext());
final ConfigurableApplicationContext springContext =
(ConfigurableApplicationContext) springWebContext;
return springContext;
}
i.e. it gets it from the servlet context, an attribute which can set
be set in a web.xml as follows:
<web-app>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
(if you stick the applicationContext.xml in the same location as the
web.xml then AFAIK you do not require the above.
I do not know how the ConfigurableApplicationContext is obtained when
the configuration is defined within a spring configuration file as you
have done. Under such circumstances it might be necessary to extend
the SpringServlet and override the getDefaultContext (with changes to
make it protected).

Most people i have seen utilizing Jetty/Jersey/Spring have configured
Jetty programatically, or using a web.xml, for example (just Jetty &
Jersey, no Spring):
