Hi,

We are migrating an application from hibernate 3.2.3.GA to hibernate 4.1.1.Final. IN the previous application, TransactionHelper is used to generate the IDs.

I want to reuse that Id generator in Hibernate 4.1.1.Final. But TransactionHelper.java has been deleted from Hibernate 4.1.1.Final.

Can anyone please Help me in this regard?
The code snippet is below:

public class IdGenerator implements IIdGenerator
{

@Override
public Long createIdInCurrentTransaction(final String entityName)
{
return this.createIdsInCurrentTransaction(entityName, 1)[0];
}

@Override
public Long[] createIdsInCurrentTransaction(final String entityName,
final int idCount)
{
Long[] ids = null;
try
{
final Connection connection = this.getSession().connection();
ids = this.getIds(connection, entityName, idCount);
}
catch (final SQLException e)
{
throw new InfrastructureException(e);
}
return ids;
}

@Override
public Long createIdInNewTransaction(
final ISessionProvider sessionProvider, final String entityName)
{
final TransactionHelper helper = new TransactionHelper()
{
protected Serializable doWorkInCurrentTransaction(
final Connection conn, final String sql) throws SQLException
{
return IdGenerator.this.getIds(conn, entityName, 1);
}
};

final Long[] ids = (Long[]) helper
.doWorkInNewTransaction((SessionImplementor) sessionProvider
.getSession());
return ids[0];
}

@Override
public Long peekNextId(final String entityName)
{
Long id = null;
try
{
final Connection connection = this.getSession();
final IdPeekerDcb dcb = new IdPeekerDcb(entityName);
dcb.execute(connection);
id = dcb.getNextGeneratedId();
}
catch (final SQLException e)
{
throw new InfrastructureException(e);
}
return id;
}

protected Session getSession()
{
// return
// ServerHelperLocator.getContainerSessionProvider().getSession();
return HibernateUtil.getSessionFactory().getCurrentSession();
}

private Long[] getIds(final Connection conn, final String entityName,
final int idCount) throws SQLException
{
final IdGeneratorDcb dcb = new IdGeneratorDcb(entityName, idCount);
dcb.execute(conn);
return dcb.getDecoratedIds();
}

}

Thanks in advance.

Giriraj.
