Question

我正在使用eclipse火星并且似乎能够通过使用这些库在独立应用程序（没有glassfish / jboss）中使用JPA：

eclipselink.jar
javax.persistence_2.1.0.v201304241213.jar
org.eclipse.persistence.jpa.jpql_2.5.2.v20140319-9ad6abd.jar

但是当我构建和部署我的应用程序时，我不断收到以下错误。我的java版本会不重要？我在生产板上使用1.6.0 24 32位，而我的IDE是64位系统。当我在NetBeans中创建测试项目时，包含了上面的库，因此我也可以在NetBeans中使用JPA。我是否遗漏了额外的库或者我的部署可能出现了问题？任何建议都非常感谢。

在生产系统上找不到JPA类
