Weblogic с Hibernate, получающим javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Не удалось открыть соединение

Question

Я перейдя из JBoss в Weblogic 12C, весь проект работал хорошо на JBoss, но при попытке перейти на Weblogic i имеют эту ошибку. Таким образом, некоторые контекст:

Моя база данных: Oracle XE Application Server: WebLogic 12С

В сценарии запуска startWebLogic.cmd я добавил:

set PRE_CLASSPATH=%MW_HOME%\oracle_common\modules\javax.persistence_2.1.jar;%MW_HOME%\wlserver\modules\com.oracle.weblogic.jpa21support_1.0.0.0_2-1.jar 

На Weblogic консоли в Сервисы -> Источники данных i создал источник данных

Имя: OracleDS

JNDI Имя: u_interface

URL: JDBC: оракул: тонкий: @localhost: 1521: х

Класс драйвера: oracle.jdbc.xa. client.OracleXADataSource

Я могу видеть на JNDI именах, что u_interface есть.

Я смог проверить подключение к базе данных на Weblogic.

Теперь мое приложение:

pom.xml

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-entitymanager</artifactId> 
    <version>3.6.0.Final</version> 
    <scope>test</scope> 
</dependency> 
<dependency> 
    <groupId>javax</groupId> 
    <artifactId>javaee-api</artifactId> 
    <version>6.0</version> 
    <type>jar</type> 
    <scope>provided</scope> 
</dependency> 

persistence.xml

<persistence-unit 
name="OracleDS" 
transaction-type="JTA"> 
    <provider>org.hibernate.ejb.HibernatePersistence</provider> 
    <jta-data-source>u_interface</jta-data-source> 
    <properties> 
     <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.WeblogicJtaPlatform" /> 
      <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/> 
      <!-- property name="hibernate.hbm2ddl.auto" value="validate"/--> 
      <!--property name="hibernate.show_sql" value="true" /--> 
      <property name="hibernate.default_batch_fetch_size" value="8"/> 
      <property name="hibernate.max_fetch_depth" value="3"/> 
    </properties> 

EJB-где у меня есть менеджер сущности:

@Stateful(mappedName="/ModuleDao") 
    public class ModuleDao implements ModuleDaoRemote { 

    @PersistenceContext(unitName = "OracleDS", type = PersistenceContextType.TRANSACTION) 
    private EntityManager em; 

Метод getModuleByName, который вы можете видеть на трассе стека.

@SuppressWarnings("unchecked") 
    public Module getModuleByName(String name) { 
     List<Module> local = null; 
     CriteriaBuilder cb = getEntityManager().getCriteriaBuilder(); 
     CriteriaQuery<Module> cq = cb.createQuery(Module.class); 
     Root<Module> root = cq.from(Module.class); 

     Predicate cond1 = cb.equal(root.get(Module_.name), name); 
     cq.where(cb.and(cond1)); 

     Query query = getEntityManager().createQuery(cq); 
     local = query.getResultList(); 
     if(local != null && !local.isEmpty()) { 
      return local.get(0);   
     } else { 
      return null; 
     } 
    } 

Я получаю ошибку на линии

local = query.getResultList(); 

Интерфейс:

@Remote 
public interface ModuleDaoRemote 

Таким образом, в другом классе я впрыснуть EJB успешно, но когда я называю метод

getModuleByName("Some string")

Я получаю сообщение об ошибке:

Нужна помощь! Пожалуйста, не стесняйтесь спрашивать дополнительную информацию.

Answer 1

Итак, теперь его работа.

Поскольку Weblogic является закрытым источником, а NPE - кодом сервера приложений, я попытался изменить версию Hibernate, и я думаю, что существует некоторый конфликт между последней версией WebLogic 12C и Hibernate (4.3.9), поскольку с Hibernate 4.1.1 его работа в настоящее время.

Благодарим за помощь.

Answer 2

Я работал над WebLogic один раз, не нужно ничего тестировать прямо сейчас, но это не похоже на то, что имя файла jta-данных JPA завершено, не нужно ли быть java : // u_interface?

Answer 3

Я не уверен в справедливости своего решения, но имею большой опыт работы с weblogic.

Вы используете hibernate-entitymanager 3.6, которые предоставляют jpa 2.0. Попробуйте обновить hibernate-entitymanager до последней версии или проекта понижения до jpa 2.0

По моему мнению, веблогика болезненно относится к модификации внутреннего баннера. Если вы ограничены сервером приложений, то лучшим решением будет переход на jpa2.0.
