I think this is how AsyncContextImpl creates async listeners (lines 228ff) @Override public <T extends AsyncListener> T createListener(Class<T> clazz) throws ServletException { T listener = null; try { listener = clazz.newInstance(); } catch (InstantiationException e) { ServletException se = new ServletException(e); throw se; } catch (IllegalAccessException e) { ServletException se = new ServletException(e); throw se; } return listener; }
but the 3.0 spec section 15.5 page 179 says Annotations must be supported on the following container managed classes that implement the following interfaces and are declared in the web application deployment descriptor or using the annotations defined in Section 8.1, “Annotations and pluggability” on page 8-61 or added programmatically. and includes AsyncListener in the table following. So shouldn't this be using the instance manager to create the instance so the resource injection machinery can do its stuff? Secondly, if you do try to register an AsyncListener with the ServletContext so it can be scanned for annotations, aside from not actually scanning it, it quickly gets to this code (ApplicationContext lines 1262 ff) @Override public <T extends EventListener> void addListener(T t) { if (!context.getState().equals(LifecycleState.STARTING_PREP)) { throw new IllegalStateException( sm.getString("applicationContext.addListener.ise", getContextPath())); } // TODO SERVLET3 // throw UnsupportedOperationException - if this context was passed to the // {...@link ServletContextListener#contextInitialized(javax.servlet.ServletContextEvent)} // method of a {...@link ServletContextListener} that was not declared // in web.xml, a web-fragment or annotated with {...@link WebListener}. boolean match = false; if (t instanceof ServletContextAttributeListener || t instanceof ServletRequestListener || t instanceof ServletRequestAttributeListener || t instanceof HttpSessionAttributeListener) { context.addApplicationEventListener(t); match = true; } if (t instanceof HttpSessionListener || (t instanceof ServletContextListener && newServletContextListenerAllowed)) { context.addApplicationLifecycleListener(t); match = true; } if (match) return; throw new IllegalArgumentException(sm.getString( "applicationContext.addListener.iae.wrongType", t.getClass().getName())); } which doesn't accept AsyncListeners. (of course it shouldn't do anything with them).
