在用MyEclipse配置一个向数据库插入值的程序遇到的问题！高手进，最好能加我QQ！
1、这个是编译错误：
（如果觉得错误内容太复杂，请着重解释画红线的错误！！）
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.

看了一些回答，主要是说*.hbm.xml里面的申明不正确，即这句话需要改正：
<!DOCTYPE hibernate-mapping PUBLIC 
  "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
  "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
但是我觉得这句话没错，一定有其它原因错误，特别是上面报的错误："[xX][mM][lL]" 是什么意思？

如果想看源代码的请写上你们的QQ，我会一一拜访，虚心请教！或者加我QQ：623041460 可以远程给你看我执行过程！万分感激，同时结交良友！
