JPA正在連接到一個不存在的HSQL數據庫？

Question

我在EclipseLink實現中使用JPA，並使用Spring注入我的實體管理器工廠。我正在通過Eclipse測試我的應用程序和TomEE服務器（Tomcat + Java EE）。

由於某些原因，當我讀取日誌時，似乎JPA連接到我的Oracle數據庫，但也連接到我沒有配置到任何位置的HSQL數據庫。

我知道我的配置中肯定有一些非常錯誤的東西，但我無法弄清楚它是什麼。

這是我的persistence.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="2.0" 
    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"> 

     <persistence-unit name="pu" transaction-type="JTA"> 
      <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> 


      <properties> 
       <property name="eclipselink.target-database" value="org.eclipse.persistence.platform.database.oracle.OraclePlatform" /> 
       <property name="javax.persistence.jdbc.driver" value="oracle.jdbc.driver.OracleDriver" /> 

       <property name="eclipselink.logging.level" value="FINEST" /> 
       <property name="eclipselink.logging.parameters" value="true" /> 
       <property name="eclipselink.logging.level.sql" value="FINEST" /> 
      </properties> 
     </persistence-unit> 
</persistence> 

，這是我的applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:security="http://www.springframework.org/schema/security"

     <property name="dataSource" ref="dataSource" /> 
     <property name="loadTimeWeaver"> 
      <bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" /> 
     </property> 
    </bean> 

    <bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager"> 
     <property name="transactionManagerName" value="java:comp/env/comp/TransactionManager"/> 
    </bean> 

    <context:component-scan base-package="com.example" /> 
    <jpa:repositories base-package="com.example.model.dao" /> 
</beans> 

UPDATE：這似乎是TomEE的錯，因爲當我刪除HSQLDB-2.2。從它的lib目錄8.jar我得到這個錯誤在日誌中：

我找到了類似this的東西。這意味着有嵌入式HSQLDB的eclipseLink版本，您可能已經掌握了它。嘗試調查並獲取沒有HSQLDB的eclipseLink。
