私は初めてhibernateを学習しているので、エラーを見つけることができません。 student007テーブルがデータベースに作成され、クライアントクラスが実行されました。私が理解しているエラーを分析することによって、sessionfactoryパートに問題があります。また、Oracleドライバは、クラスが見つからない例外 student.hbm.xmlHibernateのbuildSessionFactoryによってClassNotFoundExceptionがスローされました

を言うと、エラーがありますpackage test;

import beans.Student;
public class Client {
