Hello,
I'm trying to inject sl4j logger into my Singleton Session Bean.

Code :

import java.util.ArrayList;

import javax.annotation.PostConstruct;
import javax.ejb.Singleton;
import javax.ejb.Startup;
import javax.inject.Inject;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.slf4j.Logger;

import com.magti.billing.customercare.usemanagement.beans.entity.User;

/**
 * Session Bean implementation class UserManagerFascade
 */
@Singleton(mappedName = "UserManagerFascade")
@Startup
public class UserManagerFascade implements UserManagerFascadeRemote,
          UserManagerFascadeLocal {

     private @Inject Logger logger;

     @PersistenceContext(unitName = "Oracle")
     private EntityManager oracleManager;

     private ArrayList<User> users;

     @SuppressWarnings({ "unused", "unchecked" })
     @PostConstruct
     private void startup() {
          try {          
               logger.info("Retrieving Users From Database ... ");
               users = (ArrayList<User>) oracleManager.createNamedQuery(
                         "Users.findAll").getResultList();
               logger.info("Retrieving Users From Database Finished Successfully.");
          } catch (Exception e) {
               e.printStackTrace();
               logger.info("Retrieving Users From Database Finished Successfully.");
          }
     }

     public ArrayList<User> getUsers() {
          return users;
     }
}

My Env. :
JBoss Application Server : jboss-6.0.0.20101110-CR1

Documentation URL

But I've this error :

Any Idea ?
