我正在使用Google App Engine(appengine-java-sdk-1.6.6)为使用JDO和maven(maven-gae-plugin)的应用程序进行项目结构和构建.构建是成功的,同时使用DataNucleus Enhancer增强我的域类.
运行应用程序时,我遇到此问题:找不到类org.datanucleus.api.jdo.PersistenceManagerFactoryClass.任何人都可以建议.谢谢
PS:我已经做了一个grep(在linux上)在APP Engine SDK文件夹中找到PersistenceManagerFactoryClass,我找不到它.
