このサイトhttps://schuchert.wikispaces.com/JPA+Tutorial+1+-+Getting+Startedに記載されている非常に単純な例で JPA-Hibernate を学習しようとしてい ます (代替リンクも試しましたが、すべて終了しました同じ問題で）

ここで私の例を簡単に説明する前に、重要な例外をリストしました。

Explicit persistence provider error(s) occurred for "examplePersistenceUnit" after trying the following discovered implementations: org.hibernate.ejb.HibernatePersistence from provider: org.hibernate.ejb.HibernatePersistence
Caused by: org.hibernate.HibernateException: Unable to build the default ValidatorFactory
Caused by: javax.validation.ValidationException: Could not create Configuration.
    at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:175)
Caused by: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

プロジェクトの構成は以下のとおりです。 persistence.xml {src フォルダ ディレクトリ内 META-INF}

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">
    <persistence-unit name="examplePersistenceUnit" 
                      transaction-type="RESOURCE_LOCAL">     
       <properties>
            <property name="hibernate.show_sql" value="false" />
            <property name="hibernate.format_sql" value="false" />

            <property name="hibernate.connection.driver_class" 
                      value="org.hsqldb.jdbcDriver" />
            <property name="hibernate.connection.url" 
                      value="jdbc:hsqldb:mem:mem:aname" />
            <property name="hibernate.connection.username" value="sa" />

            <property name="hibernate.dialect" 
                      value="org.hibernate.dialect.HSQLDialect" />
            <property name="hibernate.hbm2ddl.auto" value="create" />
        </properties>
    </persistence-unit>
</persistence>

そして、次のことを行う単純なjunitクラスがあります

@Before
    public void init(){
         BasicConfigurator.configure();
            Logger.getLogger("org").setLevel(Level.TRACE);
        emf= Persistence.createEntityManagerFactory("examplePersistenceUnit");
        em = emf.createEntityManager();

    }

誰でもこれを解決するのを手伝ってくれますか?フォーラムで検索して逆コンパイラでデバッグしようとしましたが、役に立ちません

クラスパスに Hibernate バリデーターはありますか?

Maven を使用している場合は、それぞれの Hibernate バージョン ()の依存関係を追加するだけです。
