才开始学hibernate，对着网上的一个小例子操作。结果出现如下问题：
- Java code
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).log4j:WARN Please initialize the log4j system properly.org.hibernate.HibernateException: Could not parse configuration: /hibernate.cfg.xml at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1380) at org.hibernate.cfg.Configuration.configure(Configuration.java:1314) at org.hibernate.cfg.Configuration.configure(Configuration.java:1300) at com.elva.hibernate.UserTest.main(UserTest.java:7)Caused by: org.dom4j.DocumentException: Error on line 11 of document : The string "--" is not permitted within comments. Nested exception: The string "--" is not permitted within comments. at org.dom4j.io.SAXReader.read(SAXReader.java:482) at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1370) ... 3 more
一直找不到原因，请高手不吝赐教！谢谢！
