Hibernate第一个事例的javax.naming.NoInitialContextException

1.如果出现这样的提示，意思是说your slf4j包的版本不兼容，但是不必管他，这句的具体产生原因，还待高人解答。
SLF4J: The requested version 1.6 by your slf4j binding is not compatible with [1.5.5, 1.5.6, 1.5.7, 1.5.8]
SLF4J: See http://www.slf4j.org/codes.html#version_mismatch for further details.
15 [main] INFO org.hibernate.cfg.Environment - Hibernate 3.3.2.GA
31 [main] INFO org.hibernate.cfg.Environment - hibernate.properties not found
31 [main] INFO org.hibernate.cfg.Environment - Bytecode provider name : javassist
2.如果报出如下异常：
1109 [main] WARN org.hibernate.impl.SessionFactoryObjectFactory - Could not bind factory to JNDI
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial

------解决方法--------------------------------------------------------
应该是jndi没有配置好
------解决方法--------------------------------------------------------
配置文件名是不是hibernate.cfg.xml?
  代码new Configuration().configure().buildSessionFactory()；是指读入默认名为hibernate.cfg.xml的配置文件。
------解决方法--------------------------------------------------------
  把
  <session-factory name="eheshnew">
  改成
  <session-factory >
  name="xxxx" 是为了把SessionFactory的唯一实例bind到jndi上的，这样可以通过new InitialContext().lookup("xxxx")来得到SessionFactory，不过实际上没什么用处。
  非j2ee容器下直接执行或容器不支持jndi动态bind（如tomcat）都会出现这个问题。
