Hibernate version:3.2.4.sp1

Full stack trace of any exception that occurs:
org.hibernate.TransactionException: Could not register synchronization for container transaction
at org.hibernate.transaction.CMTTransaction.begin(CMTTransaction.java:45)
at org.hibernate.impl.SessionImpl.beginTransaction(SessionImpl.java:1326)

Name and version of the database you are using: oracle 10

The generated SQL (show_sql=true):

Debug level Hibernate log excerpt: debug

i will apreciate help, i am search in google but i don't find many.

hello, i am run with hibernate good, i haved the transction manager manually and run ok, but now i am tryting of change to EJB/CMT, mi service run before whithout EJB/CMT, i make this to use EJB/CMT

delete the commit and rollback, also the session.begintransaction() and the session.close, y would like that the oc4j make this for me

this is my EJB

Code:

package facade.bean;

import javax.ejb.Stateless;
import javax.ejb.TransactionAttribute;
import javax.ejb.TransactionAttributeType;
import javax.ejb.TransactionManagement;
import javax.ejb.TransactionManagementType;



@Stateless (name = IAdministrativeFacade.JNDI_NAME )

public class AdministrativeBean implements IAdministrativeFacade{

@TransactionAttribute(TransactionAttributeType.REQUIRED)
   public ClientVO registrarTransactionConfig(ClientVO clientVO) throws TxServiceException{
   transactionService.registrateOrUpdateTransactionConfig(clientVO);
}

}

and this is my Transactionserviceimpl

Code:

public class TransactionServiceImpl implements ITransactionService{
   public Object registrateOrUpdateTransactionConfig(ClientVO clientVO) throws TXLogicException {
try
         {
            session=HibernateUtil.currentSession();
//            tr=session.beginTransaction();

//processss
//tr.commit()
}
         catch(Exception e)
         {
            e.printStackTrace();
//            tr.rollback();
            
             

         }
         finally
         {
            if(session!=null)
            {
               session.close();
            }
         }
}
}

and fynally this is the hibernate.cfg.xml

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
      "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.datasource">jdbc/CoreTXDS2</property>
<property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.max_fetch_depth">1</property>
        <property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>
       <property name="hibernate.transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</property>
      <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.OC4JTransactionManagerLookup</property>
   <property name="hibernate.current_session_context_class">thread</property>
      <property name="hibernate.autocommit">true</property>
      <property name="hibernate.connection.autocommit">true</property>
