Yes, you have to create the sub resource using a ResourceContext , I use
this:

        @Context private ResourceContext rs;

        /**
         * Always use this method in sub resource locators to instantiate
the sub resource.
         * Propagates injected data from root resource to sub resource.
Care must be taken that
         * the sub resource has the proper scoping depending on its use.
If you need to create
         * collections of these objects make sure it's @Scope is
"prototype"! If the scope is
         * "request", only one instance will be created per request....
Using this method also
         * allows the use of the @Component and @Resource annotations in
the sub resource to inject
         * spring beans defining services.
         *
         * @param <T> type of the sub resource to create
         * @param clz class of the sub resource to create
         * @return instance of the sub resource.
         */
        public <T extends ApplicationResource> T
createSubResource(Class<T> clz) {
                try {
                        return rs.getResource(clz);
                } catch (Exception e) {
                        e.printStackTrace();
                        throw new WebApplicationException(Response.
serverError().entity("Could not create sub resource of type " +
clz.getName()).build());
                }
        }

Subject
[Jersey] auto injection for sub-resources






It seems that there is no autowire for the @context defined in the
sub-resources.

I have a sub-resource which has two @Context fields

    protected @Context HttpContext hc;
    protected @Context ServletContext servletContext;

When debugging, I can see both hc and servletContext are null.

Did I miss anything here?

Thanks a lot,
Kevin
