Access ServiceBean from EJB3 - ejb-3.0

Question

i implements this tutorial, but i cant access the service from EJB3.
My ejb looks like this:
#Stateless
public class Authentication implements AuthenticationRemote {
private ServiceTwoManagement man;
...
}
#EJB will throw: java.lang.RuntimeException: Could not resolve #EJB reference:
Any Suggestions

Answer 1

You guys had no chance to post an concrete answer (many informations hidden), i currently found either an clean solution or an buggy workaround. In second case: i would be glad to see any better solution like i found.
My solution was to create an service-bean (3rd bean) hold's all the TransportObjects.
#Service defines an Singleton, so i get close to the GoF-Pattern using the Singleton-Pattern.
Finally my solution looks like this:
package org.gegenakw.ejb.user;
import java.security.NoSuchAlgorithmException;
import java.util.List;
import java.util.logging.Logger;
import javassist.NotFoundException;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.persistence.PersistenceContext;
import org.antiakw.exceptions.authentication.AccountAlreadyExistsException;
import org.antiakw.exceptions.authentication.IllegalLoginException;
import org.antiakw.exceptions.authentication.NotYetActivatedException;
import org.gegenakw.Utils;
import org.gegenakw.ejb.extern.RegistrationEmailsTransportObjectHolder;
import org.gegenakw.ejb.interfaces.RegistrationTransferObject;
import org.hibernate.Criteria;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.Transaction;
import org.hibernate.criterion.Restrictions;
import org.hibernate.validator.InvalidStateException;
import org.jboss.ejb3.annotation.Depends;
import de.antiakw.jpa.beans.Benutzer;
/**
* Session Bean implementation class Authentication
*/
#Stateless
public class Authentication implements AuthenticationRemote {
public static Logger log = Logger.getLogger("Authentication");
#PersistenceContext(unitName = "gegenakwjpa")
Session hibernateSession;
// #EJB
private List<RegistrationTransferObject> registration = RegistrationEmailsTransportObjectHolder.getInstance();
#Override
public void createAccountCheckDuplicates(String email, String pass)
throws InvalidStateException, AccountAlreadyExistsException {
...
}
...
}
My RETOH looks like this:
package org.gegenakw.ejb.extern;
import java.util.ArrayList;
import java.util.List;
import javax.annotation.PostConstruct;
import org.gegenakw.ejb.interfaces.RegistrationTransferObject;
import org.jboss.ejb3.annotation.Management;
import org.jboss.ejb3.annotation.Service;
#Service(objectName = "gegen-akw:service=RETOH")
#Management(List.class)
public class RegistrationEmailsTransportObjectHolder extends ArrayList<RegistrationTransferObject> {
private static RegistrationEmailsTransportObjectHolder me;
public static RegistrationEmailsTransportObjectHolder getInstance() {
return me;
}
#PostConstruct
public void create() throws Exception {
me = this;
}
}
And my Job looks like this:
package de.antiakw.service.email;
import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.NoSuchProviderException;
import java.security.PrivateKey;

import javax.ejb.MessageDriven;
import javax.mail.Message.RecipientType;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
#ResourceAdapter("quartz-ra.rar")
#MessageDriven(activationConfig = { #ActivationConfigProperty(propertyName = "cronTrigger", propertyValue = "0 * * * * ?") }
)
public class RegistrationEmails implements Job {
public static final Logger log = Logger.getLogger("RegistrationEmails");
private static java.security.cert.Certificate certificate;
#Depends("gegen-akw:service=RETOH")
private List<RegistrationTransferObject> registrationMailHolder;
#Resource(mappedName = "java:Gegen-AKW-Mailsystem")
javax.mail.Session mailSession;
#Override
public void execute(JobExecutionContext arg0) throws JobExecutionException {
synchronized (registrationMailHolder) {
#JavaKaBaby: to folow your needs, i post my stactrace using #EJB instad of singleton-pattern (i hope the problem is comprehesible withal my workaround):
