 Hi All,

 The problem is :  I got a NullPointerException after using @Inject
 environment : wicket 1.6 snapshot - cdi (weld) - inject - 
 NullPointerException - tomcat 7 / jboss AS 7

 module 1 : bookstoreservice  (with a beans.xml file)
 module 2 : bookstoreweb  (with a beans.xml file)

 in the bookstoreservice module I have these 2 classes:

 @ApplicationScoped
 public class Clock {
 public DateTime getTime() {
 return new DateTime().now();
 }
 }

 @ApplicationScoped
 public class BigBenClock {

 @Inject
 Clock clock;

 public BigBenClock() {
 }

 public DateTime getBigBenTime() {
 return clock.getTime().plusHours(2);
 }
 }



 First use : All works fine

 In a webpage, I have

 @Inject
 Clock clock;

 @Inject
 BigBenClock bigBenClock;

 add(new Label(time, new PropertyModel(this, clock.time)));
 add(new Label(bigBenTime, new PropertyModel(this, 
 bigBenClock.bigBenTime)));

 All works fine, thanks to Igor's example 
 https://www.42lines.net/2011/11/15/integrating-cdi-into-wicket/


 Second use : NullPointerException

 If I use the injection in the bookstoreservice module with no injection in 
 the webpage like this


 @Inject
 Clock clock;

 add(new Label(time, new PropertyModel(this, clock.time)));

 BigBenClock bigBenClock = new BigBenClock();
 DateTime bigBenTime = bigBenClock.getBigBenTime();

 I get a NullPointerException.  The BigBenClock's clok is null.
 Same result in Tomcat 7 and Jboss AS7.


 This is how I start the Wicket application

 getComponentInstantiationListeners().add(new JavaEEComponentInjector(this, 
 new ModuleJndiNamingStrategy()));
 BeanManager beanManager = (BeanManager)getServletContext().getAttribute(  
 Listener.BEAN_MANAGER_ATTRIBUTE_NAME);
 new 
 CdiConfiguration(beanManager).setPropagation(ConversationPropagation.NONE).configure(this);


 Any advice ?

 Thanks

 François

looks like a cdi problem since the NPE is inside BigBenClock which is
created and injected by cdi... strange.

At the startup I can see
WELD-000106 Bean: Managed Bean [class bookstoremodel.cdi.BigBenClock] with 
qualifiers [@Any @Default]
BigBenClock reacts as it was not managed.
