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 ?
Thanks again ALRubinger In advance.
