Duplicate   class/entity   mapping   com.ld.hibernate.News  
  重复映射News类  
   
  是不是配置文件中已经有映射到news的类Top

Web程序光看异常只能看个大概。建议Lz用调试，自己调试一下就会知道错误在哪了。Top

2006-2-9   15:45:12   org.hibernate.cfg.Configuration   configure  
  信息:   configuring   from   resource:   /hibernate.cfg.xml  
  2006-2-9   15:45:12   org.hibernate.cfg.Configuration   getConfigurationInputStream  
  信息:   Configuration   resource:   /hibernate.cfg.xml  
   
  上面信息明显存在两个hibernate.cfg.xml文件  
  所以下面出现双重映射  
   
  如果用eclipse的话,可在左边的树里按F5刷新一下,看是否存在两个hibernate的配置.

  好像是没有找到News.hbm.xml这个映射，检查一下有没有Top
