您好，感谢您的帮助！
我正在使用Weblogic 10.3.0.0，其JDBC数据源配置为使用oracle.jdbc.OracleDriver中的瘦驱动程序。驱动程序库是ojdbc6.jar，驱动程序版本是11.1.0.6.0-Production。在我的本地客户端，我使用的是11.2.0.3.0版本，但我也尝试了与服务器相同的版本，但无济于事。
问题的症状以两个NullPointerExceptions的形式出现：

我已经介绍了所有内容，直到weblogic.jdbc.rmi.SerialConnection.prepareStatement，因为该源不是公共的。问题似乎是返回一个空的PreparedStatement，然后传递给那两个抛出NPE的方法。
数据源被声明为Spring bean（为了安全起见，已删除了URL和凭据）：
<bean id="datasource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>jdbc/DS</value>
</property>
<property name="resourceRef">
<value>true</value>
</property>
<property name="jndiEnvironment">
<props>
<prop key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</prop>
<prop key="java.naming.provider.url">t3://000.00.00.000:15031/</prop>
<prop key="java.naming.security.principal">principal</prop>
<prop key="java.naming.security.credentials">credentials</prop>
</props>
</property>
</bean>
我还在本地运行的WebLogic实例的JNDI树中设置了相同的确切数据源，并且没有例外。 （可能需要注意的是，我的本地WebLogic版本是10.3.2）：
<bean id="datasource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>jdbc/DS</value>
</property>
<property name="resourceRef">
<value>true</value>
</property>
<property name="jndiEnvironment">
<props>
<prop key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</prop>
<prop key="java.naming.provider.url">t3://localhost:7001/</prop>
<prop key="java.naming.security.principal">principal</prop>
<prop key="java.naming.security.credentials">credentials</prop>
</props>
</property>
</bean>
最后，通过直接在Spring bean中声明数据源而不引用JNDI，我也让它工作得很好：
<bean id="datasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.OracleDriver" />
<property name="username" value="username" />
<property name="password" value="password" />
<property name="url" value="jdbc:oracle:thin:@username.com.com:1530:service_name" />
</bean>
感谢任何帮助，如果有必要，我非常乐意提供更多详细信息。谢谢你的时间！
