Spring3.1 & Hibernate4 Konfiguration. Unable to load class [org.hibernate.service.jdbc.- verbindungen.intern.C3P0ConnectionProvider]

Ich versuche zur Entwicklung eines web-Projektes mit Hibernate 4 und spring 3.1. Ich erklärte sessionFactory bean in der applicationContenxt.xml.

<bean id="sessionFactory" scope="singleton" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="configLocation" value="classpath:hibernate.cfg.xml" />
    </bean>

Will ich mit Oracle-Datenbank, so dass meine hibernate.cfg.xml Datei :

<session-factory>
        <!-- Database connection settings -->
        <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
        <property name="connection.url">jdbc:oracle:thin:@localhost:1521:xe</property>
        <property name="connection.username">****</property>
        <property name="connection.password">****</property>
        <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>

        <!--
            Enable c3p0 connection pooling, because hibernate pooling is not
            prod-ready. Apparently connection.provider_class is needed in
            hibernate 3+
        -->
        <property name="connection.provider_class">
        org.hibernate.connection.C3P0ConnectionProvider</property>
        <!-- <property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property> -->
        <property name="c3p0.max_size">100</property>
        <property name="c3p0.min_size">1</property>
        <property name="c3p0.idle_test_period">30</property>

        <!-- Echo all executed SQL to stdout for debugging -->
        <property name="show_sql">true</property>

        <!-- All the entity classes for hibernate to check for annotations here
-->
        <mapping class="data.Event" />

Wenn ich die Anwendung ausführen. Ich bekomme die Ausnahmen :

Konnte ich das problem nicht lösen, wie ich bin absoluter Anfänger auf Spring und Hibernate.

Gibt es irgendjemanden, der eine Idee zu dem problem.

Sind Sie sicher, dass Sie alle Abhängigkeiten für hibernate und c3po?
