Answer 1

java.lang.ClassNotFoundException
缺包啊，缺少commons-logging.jar
来这里下http://commons.apache.org/downloads/download_logging.cgi

Answer 2

我后来又多导入了 commons-logging-1.0.4.jar 和 commons-logging-api-1.1.jar 这两外包,hibernate.cfg.xml改了几处小错误  改了的文件如下
<?xml version="1.0" encoding="UTF-8"?>

Answer 3

在Hibernate的hql中不支持 * ，你最好改一下！

Answer 4

select * from country的select *可以去掉

Answer 5

楼上的兄弟门,我己经把 select * from country 改成了 from country 了
还是报如下的错误.type Exception reportmessage description The server encountered an internal error () that prevented it from fulfilling this request.exception org.hibernate.hql.ast.QuerySyntaxError: country is not mapped. [from country]

Answer 11

country is not mapped. [from country] 
把country改成Country，你前面的Country.hbm.xml 里的class标签写的是Country

Answer 12

HQL :select * from Country c 
我在想你的Country这个类名是小写的？最好给Country写个别名 就想上面写的 Country c

Answer 13

org.hibernate.hql.ast.QuerySyntaxError: country is not mapped. [from country]说的是country没有这个类你应该把那个country的c大写才是吧，直接写成 from Country，不用select *

Answer 14

老兄:hibernate.cfg.xml 里面要设置加载Country.hbm.xml 才行啊<mapping resource="Country.hbm.xml"/>
