Hibernate e Oracle não encontra classe

Olá caros colegas,

Estou com um problemas durante todo dia, já tentei varias formas de resolver. Já fiz a intalação do hibernate diversas vezes porém desta vez o hibernate.cfg.xml não reconhece o BD e nem encontra a classe do oracle. Coloco o código abaixo:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
     "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
     <session-factory>
        
         <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
         <property name="connection.url">jdbc:oracle:thin:@192.168.2.1:1521:pa</property>
         <property name="connection.username">pa</property>
         <property name="connection.password">pa</property>
         <property name="show_sql">true</property>
         <!-- SQL dialect, especifico para a versão 9 do Oracle -->
         <property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>
        
     </session-factory>
</hibernate-configuration>

ERRO
