DAO Framework - question on thread-safety

[mfs]

Guys,

I am using ibatis DAO Framework and i had certain questions/concerns, that
whether my current DAO Manager implementation is thread safe, since
apparently the getDAO(MyDAOClass.class) method (which i am using to retrieve
the dao implementation) isn't thread safe. Also Larry mentioned in one some
other thread that there is one instance maintained of each DAO
implementation and thats yet another reason which made to me ask this...

class MyDAOManager
{
    private static DaoManager s_daoManager;

    public static synchronized DaoManager getDaoManager()
    {
      Log log = LogFactory.getLog(DAOManager.class);
      if (null == s_daoManager)
      {
          try
          {
              String daoXMLresource = "[path]/dao.xml";
              Reader reader = Resources.getResourceAsReader(daoXMLresource);
              s_daoManager = DaoManagerBuilder.buildDaoManager(reader);
              log.info("DAOManager Initialized");
          }
          catch (IOException ioe)
          {
              throw new RuntimeException("Could not initialize DaoConfig. 
Cause: " + ioe);
          }
      }
      return s_daoManager;
    }

    public static AccountDAO getAccountDao()
    {
        return (AccountDAO) getDaoManager().getDao(AccountDAO.class);
    }

    public static UserDAO getUserDao(Class interfaceClass)
    {
        return (UserDAO) getDaoManager().getDao(UserDAO.class);
    }

Thanks and Regards,
