Hello Ta Great Thanks for your post, i tried to this for couple of moth and could not resolve this problem. and ok, i did what you say i got another problem when i tried to persist in one method whats ok, there is no information persisted in database, but when i tried to flush on other method i got an error : javax.persistence.TransactionRequiredException. my example now looks like : | package com.magti.businesslayer.ejb3Fasade; | | import javax.ejb.EJB; | import javax.ejb.Remote; | import javax.ejb.Remove; | import javax.ejb.Stateful; | import javax.ejb.Stateless; | import javax.ejb.TransactionAttribute; | import javax.ejb.TransactionAttributeType; | import javax.ejb.TransactionManagement; | import javax.ejb.TransactionManagementType; | import javax.persistence.EntityManager; | import javax.persistence.PersistenceContext; | import javax.persistence.PersistenceContextType; | import javax.persistence.PersistenceProperty; | | import com.magti.businesslayer.ejb3Fasade.TestFasade; | import com.magti.businesslayer.ejb3entity.oracle.Test; | | @Stateful | @Remote(TestFasade.class) | @TransactionManagement(TransactionManagementType.BEAN) | public class TestFasadeBean implements TestFasade { | | @PersistenceContext( | type = PersistenceContextType.EXTENDED, | properties = @PersistenceProperty( | name = "org.hibernate.flushMode", | value = "MANUAL")) | EntityManager oracleManager; | Test test; | | public Long create() { | try { | test = new Test(); | test.setAge(21L); | test.setName("adsdasd"); | test.setSurname("asdasd"); | oracleManager.persist(test); | return test.getId(); | } catch (Exception e) { | e.printStackTrace(); | return 0L; | } | } | | public void comit() { | try { | oracleManager.flush(); | } catch (Exception e) { | e.printStackTrace(); | } | } | } | when i tried to flush, i got this exception : javax.persistence.TransactionRequiredException. i tried to use @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW) and @TransactionAttribute(TransactionAttributeType.SUPPORTS) but it could not resolve problem :( have any idea ?
