GAE/JDO - jdopersistencemanagerfactory не найден

Прежде всего, это мой первый раз, я из Бразилии, также хотел бы сказать спасибо заранее всем, кто может мне помочь. Кроме того, это мой первый опыт работы с GAE, и мне очень нравится эта услуга. Я работаю с GAE на некоторое время, и я довольно успешно использую GAE.GAE/JDO - jdopersistencemanagerfactory не найден

я пытаюсь сделать настойчивость в GAE, ошибка у меня есть сообщение об ошибке:

javax.jdo.JDOFatalUserException: Класс org.datanucleus.api.jdo .JDOPersistenceManagerFactory не был найден.

Где я вставить:

MyBean p = new MyBean(la,lo); 

PersistenceManager pm = PMF.get().getPersistenceManager(); 


try{ 
    pm.makePersistent(p); 

} finally { 

    pm.close(); 
}

Я использую Maven, он приходит с файлом persistence.xml в META-INF, но я создал jdoconfig:

<?xml version="1.0" encoding="utf-8"?> 
<jdoconfig xmlns="http://java.sun.com/xml/ns/jdo/jdoconfig"

Там нет NoClassDefFoundError в том, что вы размещаете. Существует Причина: javax.jdo.JDOFatalUserException: свойство с именем javax.jdo.Pe rsistenceManagerFactoryClass должно быть указано или файл jar с меткой META-INF/se rvices/javax.jdo.PersistenceManagerFactory должен быть в пути к классам , или свойство с именем javax.jdo.option.PersistenceUnitName должно быть указано. Так почему бы не следовать сообщению? Или, может быть, вы просто не публикуете важную информацию? –

Привет, Билли, спасибо за внимание, я очень смущен этим, извините. Ну, сегодня я начал другой проект. И теперь у меня есть эта ошибка. Org.datanucleus.api.jdo.jdopersistencemanagerfactory не найден Я отредактировал thacer и pom.xml. Вы еще раз видите? – user2296305

если вы сохраняющиеся с помощью JDO with GAE/Datastore вам нужно

org.datanucleus : datanucleus-core, datanucleus-api-jdo v3.1.x 
com.google.appengine.orm : datanucleus-appengine v2.1.x

Добавьте к этому DataNucleus-энхансер v3.1.x при повышении (если не сделано с помощью Maven плагин)

я мимо этой ошибки в Eclipse, путем ввода свойств проекта - Google - App Engine и переключения версии Datanucleus JDO/JPA на 2, из неуказанных. (Ошибка в верхней части моего дампа трассировки была java.lang.ExceptionInInitializerError, если это имеет значение.)

Переключение на версию 1 сделало трюк для меня –

Извините, если это немного поздно, но я использую GAE для нескольких проектов и каждый раз сталкивался с этой ошибкой , так как в документации легко пропустить.

в каталоге приложений war/WEB-INF/classes/META-INF/, создайте файл jdoconfig.xml со следующим содержимым;

<?xml version="1.0" encoding="utf-8"?> 
<jdoconfig xmlns="http://java.sun.com/xml/ns/jdo/jdoconfig" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:noNamespaceSchemaLocation="http://java.sun.com/xml/ns/jdo/jdoconfig"> 

<persistence-manager-factory name="transactions-optional"> 
    <property name="javax.jdo.PersistenceManagerFactoryClass" 
     value="org.datanucleus.api.jdo.JDOPersistenceManagerFactory"/> 
    <property name="javax.jdo.option.ConnectionURL" value="appengine"/> 
    <property name="javax.jdo.option.NontransactionalRead" value="true"/> 
    <property name="javax.jdo.option.NontransactionalWrite" value="true"/> 
    <property name="javax.jdo.option.RetainValues" value="true"/> 
    <property name="datanucleus.appengine.autoCreateDatastoreTxns" value="true"/> 
    <property name="datanucleus.appengine.singletonPMFForName" value="true"/> 
</persistence-manager-factory>

Это указывает на экземпляр JDOPersistenceManagerFactory с именем "сделок факультативные"
