Question

The method configure() is undefined for the type Configuration

public static List<tel> getInfo(){
Configuration cfg=new Configuration();
SessionFactory sf = cfg.configure().buildSessionFactory();
org.hibernate.classic.Session session = sf.openSession();
org.hibernate.Query q=session.createQuery("from tel as c");
List<tel> l=q.list();
session.close();
sf.close();
return l;

}

Answer 1

Cannot instantiate the type Configuration
The method configure() is undefined for the type Configuration
SchemaExport cannot be resolved to a type
SchemaExport cannot be resolved to a type

这个的意思就是说：
1.类型Configuration不能定义方法configure()
2.SchemaExport不能审明一个变量

我想这个大概是你没有将Hibernate的jar包放入classes/lib下面吧，程序找不到就报错了，你再试试
