hibernate separate jar lib

Question

私は休止状態のアプリケーションを持っています。すべてのエンティティクラスが別のjarファイルにプラグインされています。

<bean id="myEntityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
    <property name="persistenceXmlLocation" value="classpath:/META-INF/persistence.xml" /> 
    <property name="persistenceUnitName" value="MyPersistenceUnit" /> 
    <property name="dataSource" ref="myDataSource" /> 
    <property name="jpaVendorAdapter" ref="jpaVendorAdapter" /> 
    <property name="jpaDialect" ref="jpaDialect" /> 
    <property name="packagesToScan" value="mypackage" /> 
</bean> 

をとのpersistence.xml：configが以下である

<?xml version="1.0" encoding="UTF-8"?> 
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0" > 
    <persistence-unit name="MyPersistenceUnit"> 
     <properties> 
      <property name="hibernate.dialect" value="mypackage.domain.MyInformixDialect"/> 
      <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/> 
      <property name="hibernate.show.sql" value="false"/> 
      <property name="hibernate.current_session_context_class" value="thread"/> 
      <property name="hibernate.archive.autodetection" value="class"/> 
     </properties> 
    </persistence-unit> 
</persistence> 

私は自分のアプリケーションを実行すると、私はデバッグしようとしたとき、私はセクションを見つけ

java.lang.ArrayIndexOutOfBoundsException: 0 

取得：

file: package org.hibernate.hql.internal.QuerySplitter 

if (results.length == 0) { 
    LOG.noPersistentClassesFound(query); 
} 

行130、休止状態バージョンは4.3.8です。最終的に

私のエンティティはロードされていないようです。どうして？ jarファイルからスキャンできないのはなぜですか？私はパッケージ名をチェックし、persistence.xmlはMETA-INFフォルダにあります。何が問題なのですか？

UPDATE

スタックトレースは以下の通りです：

Answer 1

あなたのエンティティが外部のjarファイルであるJPAを伝えることができて得るものです。

参考：それはアプリケーションではなく、ジャー右側にありますJPA 2.0: Adding entity classes to PersistenceUnit from different jar automatically

<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="2.0" ... > 
    <persistence-unit name="primary"> 
     <jta-data-source>java:jboss/datasources/mysource</jta-data-source> 

     <jar-file>lib/${common.jar}</jar-file> 
     <jar-file>lib/${foo.jar}</jar-file> 

     ... 
    </persistence-unit> 
</persistence>
