Spring + Hibernate + Quartz: dynamic work

I want to create dynamic jobs using Quartz, Spring and Hibernate. Users interact with the web service to create jobs of this class:

public class StartJobSpring extends QuartzJobBean {

    private String jobId;
    private String jobType;

    @Autowired
    private NoaJobInstancesDAO njiDAO;

    @Transactional
    @Override
    protected void executeInternal(JobExecutionContext context)
            throws JobExecutionException {

        JobKey key = context.getJobDetail().getKey();
        JobDataMap dataMap = context.getMergedJobDataMap();

        // some logic
        njiDAO.create(instanceUUID, noaJob.getNoaJob(jobId), jobType);
    }
}

      

        
        
        
      

    

NoaJobInstancesDAO is a simple DAO class that uses the Hibernate EntityManager :

@Repository
public class NoaJobInstancesDAOHibImpl implements NoaJobInstancesDAO {

    @PersistenceContext
    private EntityManager entityManager;

    @Override
    @Transactional
    public NoaJobInstanceJPA create(NoaJobInstanceJPA entity) {
        entityManager.persist(entity);
        return entity;
    }

    @Override
    public void create(String instance_uuid, NoaJobJPA job, String job_type) {
        NoaJobInstanceJPA entity = new NoaJobInstanceJPA(instance_uuid, job,
                job_type, "CREATED", null, null, "", "N", "N");
        this.create(entity);
    } 
}

      

        
        
        
      

    

The problem is that when this job fires an exception is thrown:

javax.persistence.TransactionRequiredException: No transactional EntityManager available

      

        
        
        
      

    

and I can't figure out why! I plan to work this way in the Manager class

JobDetail job = newJob(StartJobSpring.class).withIdentity(//anId)
                .setJobData(//aJobMap).build();
getScheduler().getObject().scheduleJob(job, trigger);

      

        
        
        
      

    

where the scheduler is connected to the dispatcher as

@Autowired
private ApplicationContext applicationContext;

@Bean
SchedulerFactoryBean schedulerFactoryBean(DataSource dataSource, JpaTransactionManager transactionManager) {

    SchedulerFactoryBean bean = new SchedulerFactoryBean();

    AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
    jobFactory.setApplicationContext(applicationContext);
    bean.setJobFactory(jobFactory);

    bean.setTransactionManager(transactionManager);

    return bean;
}

      

        
        
        
      

    

The AutowiringSpringBeanJobFactory class is the same as Autowiring .

There is something wrong in my suggestion in the scheduler explorer. Actually, I don't understand how I can get the application context.

EDIT1: The application context looks correct. The problem may not be there.

EDIT2: I am using one bean config (not xml files). Here's the main methods:

@Bean
LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource   dataSource) {
     LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
     entityManagerFactoryBean.setDataSource(dataSource);
     entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
     entityManagerFactoryBean.setPackagesToScan("package");

    Properties jpaProperties = new Properties();
    jpaProperties.put("hibernate.dialect", "org.hibernate.dialect.OracleDialect");
    jpaProperties.put("hibernate.show_sql", "false");
    jpaProperties.put("hibernate.hbm2ddl.auto", "update");

    entityManagerFactoryBean.setJpaProperties(jpaProperties);

    return entityManagerFactoryBean;
}

@Bean
JpaTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
    JpaTransactionManager transactionManager = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(entityManagerFactory);
    return transactionManager;
}

@Bean
public NoaJobInstancesDAO noaJobInstancesDAO() {
    NoaJobInstancesDAOHibImpl noaJobInstancesDAO = new NoaJobInstancesDAOHibImpl();
    return noaJobInstancesDAO;
}
