> Eg:
> {code}
> @Path("resource")
> @Singleton
> public static class MySingletonResource {
>  
>     @QueryParam("query")
>     String param; // WRONG: initialization of application will fail as you cannot
>                   // inject request specific parameters into a singleton resource.
>  
>     @GET
>     public String get() {
>         return "query param: " + param;
>     }
> }
> {code}
> The exception exists for specific request objects which can injected even into constructor or class fields. For these objects the runtime will inject proxies which are able to simultaneously server more request. These request objects are HttpHeaders, Request, UriInfo, SecurityContext. These proxies can be injected using the @Context annotation
