Question

您好我试图将我的应用程序连接到Websphere中定义的数据源;当我做“测试连接”时，数据源工作得非常好。在Websphere中。但是，当我尝试使用应用程序进行连接时，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初始SessionFactory创建失败..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：＆＃34; jdbc / cmsPrueba＆＃34 ;;我尝试了这种形式：

的java：comp / env的/ JDBC / cmsPrueba

和这一个：

JDBC / cmsPrueba

我正在使用：

Websphere 7
Hibernate 2
JDK 6

这是web.xml：

尝试向您的web.xml添加资源引用，如下所示：

<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定义数据源中使用JNDI名称：jdbc/cmsPrueba

您需要在安装期间或ibm-web-bnd.xml文件中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" />
