Apache Wicket: Injecting dependencies in Session (using Guice) -

I am using and I went into problem similar to OP.

I need to follow the following to reach the DB service level (for user authentication) and do the following:

  @ Override public session new session ( Request request, reply response) {session = new migration (request); MInjector.inject (s); Return s; }   
 Unfortunately this result  
  java.lang.IllegalStateException: EntityManager is closed   
 (possibly due to fact It is that (A) I am using Open Session and (b) spreads on many requests in the session).  
 I call it injection to  AuthenticatedWebSession.authenticate  method.  
  @ Override public boolean authentication (string user name, string pass) {Injector.get () Inject (this); ...}   
 I suspect that this is not the best practice, because now I need access to the service layer in other ways, and this is not a good idea. > Injector.get (). In each such method add injector (this) .  
 My question:  
 How can I inject a session object into each request? (Or, if it's all wrong together, then whom do I use the service layer?)   
 
 < P> You can apply  IRequestCycleListener  ( Extend AbstractRequestCycleListener ) and apply:  
  @OverrideBeginRequest on Public Zero (RequestCycle Circle) {if (session .exists ()) {Injector.get () Injection (session .get ()); }}   
 Register  getRequestCycleListeners () with the  application #init ()  in your  IRequestCycleListener  (New YourRequestCycleListener () ) .
