ejb in session context is allways null - jax-rs

Question

i have created sigleton session bean which keeps one connection to my mongo database. It works well in jax-rs class when using #EJB annotation - after controller is contructed and bean is injected it calls init method anotated with #PostConstruct.
Then i created similar class, which is implementing SecurityContext. I used same pattern as in controller, but it is not working properly. init() method is never called and EJB instance is always null.
So is there a way to inject EJB to my SecurityContext implemetation ? it works well unless i try to inject and use MongoConnection
my singleton session bean I use to connect mongo database:
#Singleton
#Startup
public class MongoConnection {
#PostConstruct
public void init() {
// initialize properties
}
I use it in JAX-RS controller. it works here, also in classes inherited from EntityController.
Produces(MediaType.APPLICATION_JSON)
public class EntityController extends Application {
#Context
private UriInfo context;
**#EJB
protected MongoConnection connection;**
public EntityController() {
#PostConstruct
void init() {
...
connection.getMongo();
connection.getDatabaseName();
...
}
}
I implemented my own security context, which is looking for loged user roles in mongo database.
public class MongoSecurityContext implements SecurityContext {
**#EJB
private MongoConnection connection;**
public MongoSecurityContext() {
}
#PostConstruct
void init() {
...
connection.getMongo();
connection.getDatabaseName();
...
}
public MongoSecurityContext(ContainerRequestContext requestContext) {
token = requestContext.getHeaderString("token");
}
#Override
public boolean isUserInRole(String roleName) {
//**connection is allways null**, so it returns false;
if (connection == null)
return false;
}
}
EDIT:
I forget, i also have this warning in glassfish 4 console:
A provider extremeteacher.mongo.connection.MongoConnectionEjb registered in SERVER runtime does not implement any provider interfaces applicable in the SERVER runtime. Due to constraint configuration problems the provider extremeteacher.mongo.connection.MongoConnectionEjb will be ignored
EDIT2:
#Provider
#Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {
#Override
public void filter(ContainerRequestContext requestContext) {
requestContext.setSecurityContext(new MongoSecurityContext(requestContext)) ;
}
}

Injection does not work for objects created with new because the container is never given control to perform the injection. I recommend moving the #EJB to the filter and passing it to the MongoSecurityContext constructor.
