郁闷了好多天的问题了，帮忙看看！！
我连接的是oracle数据库，然后用hibernate映射，但是我写了一条查询语句，然后报找不到表或视图的错误。 
我写的函数如下：public List findSmeoeDMenu() 
  { 
  List list=null; 
  log.debug("find SmeoeDMenu instance"); 
  try 
  {  
  Transaction tx = getSession().beginTransaction();  
  Query q = getSession().createQuery("from SmeoeDMenu where menuLevel='1' and parentId='0' and enableFlag='Y' order by showOrder asc "); 
  list = q.list();  
  tx.commit(); 
  log.debug("find successful"); 
  return list;  
  } 
  catch(RuntimeException re) 
  { 
  log.error("find failed",re); 
  throw re; 
  } 
  }主要看sql语句就可以了，报得错误如下： 
log4j:WARN No appenders could be found for logger (com.bestoe.smeoe.hibernate.dao.SmeoeDMenuDAO). 
log4j:WARN Please initialize the log4j system properly.
