所以，我认为主要问题在这里：“jdbc/MySQLJDBCResource”的查找失败。在我的 persistence.xml 中，我设置了 jta-data-source，如您所见：
<?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="acmeauction" transaction-type ="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>jdbc/MySQLJDBCResource</jta-data-source>
<class>...[cutted]...</class>
</persistence-unit>
</persistence>
我正在使用 Glassfish v3、JPA EclipseLink：我很乐意提供任何有用的附加信息。谢谢， 安
