Spring框架jdbc無法獲取Jdbc連接異常

Question

實際上，我正在嘗試將Oracle數據庫與Spring連接，並且我正在使用下面指定的包含Oracle數據庫配置的spring-servlet.xml文件。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-   instance"xmlns:p="http://www.springframework.org/schema/p"
 xmlns:context="http://www.springframework.org/schema/context"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
  http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
  http://www.springframework.org/schema/context
  http://www.springframework.org/schema/context/spring-context-3.0.xsd">

 <!-- telling container to take care of annotations stuff -->
 <context:annotation-config />

 <!-- declaring base package -->
 <context:component-scan base-package="com.bank" />

 <!-- adding view resolver to show jsp's on browser -->
 <bean id="viewResolver"
  class="org.springframework.web.servlet.view.InternalResourceViewResolver">
 <property name="prefix" value="/WEB-INF/jsp/" />
  <property name="suffix" value=".jsp" />
 </bean>

  <!-- declare beans -->


  <bean id="PersionalDetailsdao" class="com.bank.dao.PersionalDetailsDaoImpl" />
 <bean id="persionalService" class="com.bank.services.PersionalDetailsServiceImpl" />


 <!-- declare datasource bean -->
  <bean id="dataSource"
   class="org.springframework.jdbc.datasource.DriverManagerDataSource">
   <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
   <property name="url" value="jdbc:oracle:thin:@myhost:1521:orcl" />
   <property name="username" value="SYSTEM" />
   <property name="password" value="SangamOne123" />
 </bean>
 </beans>

但是運行該應用程序后，我得到以下異常。
