Eclipselink将错误的数据库平台

Question

While trying to run a JPA application, I get:

[EL Fine]: 2014-07-09   16:55:52.532--Thread(Thread[http-bio-8080-exec-6,5,main])--Detected database platform: org.eclipse.persistence.platform.database.HSQLPlatform

Which is NOT the correct platform. (should be an Oracle thin client). The same project when checked out on a different machine works fine. Only difference that we can detect is the jdk version (13 versus 60 on mine).

My Persistance.xml looks like:


<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" 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="JPA_DatabasePU" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <non-jta-data-source>wellsDB</non-jta-data-source>
    <class>my.domain.jpaDatabase.entities.Fred.Feature</class>
    <properties>
      <property name="javax.persistence.jdbc.driver" value="oracle.jdbc.OracleDriver"/>
      <property name="javax.persistence.jdbc.url"     value="jdbc:oracle:thin:user@//db.domain.my:1521/inst"/>
      <property name="javax.persistence.jdbc.user" value="username"/>
      <property name="javax.persistence.jdbc.password" value="password"/>
      <property name="eclipselink.logging.level" value="FINEST"/>
    </properties>
  </persistence-unit>
</persistence>

What am I missing??

Answer 1

您可以尝试设置目标数据库吗？

<property name="eclipselink.target-database" value="Oracle"/>

Answer 2

Well the answer was to replace the Tomee 1.5 install with a fresh install of Tomee 1.6. I cant see difference in the conf files but there you are. From my point of view, the important thing is that this fixed the issue. The created war deploys without a problem on the production Tomee as well.
