hi all,
i'm new in ejb, and i have a problem :

in a class where i implement interface Schedulable.... in the perform() method i write this code :
UserTransaction ut = (UserTransaction)initCtx.lookup("UserTransaction");
ut.begin();
emi.persist(new RssItemBean());
ut.commit();

i got emi like this :
EntityManagerFactory emf=Persistence.createEntityManagerFactory("em");emi=emf.getEntityManager();

and i get this exception :
javax.persistence.TransactionRequiredException: no transaction is in progress
at org.hibernate.ejb.AbstractEntityManagerImpl.checkTransactionActive(AbstractEntityManagerImpl.java:123)
at org.hibernate.ejb.AbstractEntityManagerImpl.persist(AbstractEntityManagerImpl.java:128)
at services.schedulables.SchedulesForRssWorker.run(SchedulesForRssWorker.java:221)

and i know that this exception is thrown because i use the emi outside an persistence context but how can i get the persistence context ?

thanks,
chelaru.viorel
