Websphere Initial SessionFactory 创建 failed.org.hibernate.HibernateException: 找不到数据源

Question

您好，我正在尝试将我的应用程序连接到 Websphere 中定义的数据源；当我在 Websphere 中执行“测试连接”时，数据源运行良好。但是当我尝试与应用程序连接时，我在日志中遇到了这个问题：

java org.apache.openjpa.lib.conf.ProductDerivations [8/8/14 16:19:09:520 CST] 00000018 SystemErr R com.ibm.ws.persistence.WsJpaProductDerivation:java.lang.ClassNotFoundException: com.ibm.ws.persistence.WsJpaProductDerivation [8/8/14 16:23:15:269 CST] 0000002c SystemErr R Initial SessionFactory 创建 failed.org.hibernate.HibernateException：找不到数据源

这里我添加了hibernate.cfg.xml：

<hibernate-configuration>
  <session-factory>
    <property name="hibernate.connection.datasource">java:comp/env/jdbc/cmsPrueba</property>

    <property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
    <property name="use_outer_join">true</property> 
    <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>                                     


    <property name="hibernate.show_sql">false</property>

    <!-- Mapping Files -->

    <mapping resource="sisa/cms/db/mapping/CmsFaq.hbm.xml"/>

在 websphere 中，我用这个 JNDI 定义了数据源：“jdbc/cmsPrueba”；我尝试了这种形式：

java:comp/env/jdbc/cmsPrueba

还有这个：

jdbc/cmsPrueba

我正在使用：

• Websphere 7
• 休眠 2
• JDK 6

这是 web.xml：

尝试像这样将资源引用添加到您的 web.xml：

<resource-ref>
      <res-ref-name>jdbc/cmsPrueba</res-ref-name>
      <res-type>javax.sql.DataSource</res-type>
      <res-auth>Container</res-auth>
      <res-sharing-scope>Unshareable</res-sharing-scope>
</resource-ref>

在 WebSphere 中使用 JNDI 名称定义数据源：jdbc/cmsPrueba

您需要在安装期间或通过ibm-web-bnd.xml 文件将此资源引用绑定到JNDI 名称。如果你想使用绑定文件，只需添加以下行：

<resource-ref name="jdbc/cmsPrueba" binding-name="jdbc/cmsPrueba" />
