Как использовать источник данных JNDI, предоставленный Tomcat 7 весной?

Question

Я последовал за этот ответ How to use JNDI DataSource provided by Tomcat in Spring? но я получаю следующее исключение:

TOMCAT server.xml:

<GlobalNamingResources> 
<Resource 
    name="jdbc/welcome-kit" 
    global="jdbc/welcome-kit"  
    auth="Container" 
    type="javax.sql.DataSource" 
    username="name" 
    password="pass" 
    driverClassName="oracle.jdbc.driver.OracleDriver" 
    url="host/port:test" 
    maxActive="8" 
    maxIdle="4" 
/> 

context.xml кот

<ResourceLink global="jdbc/welcome-kit" name="jdbc/welcome-kit" type="javax.sql.DataSource" /> 

Интернет application web.xml:

<resource-ref> 
<description>DB Connection</description> 
<res-ref-name>jdbc/welcome-kit</res-ref-name> 
<res-type>javax.sql.DataSource</res-type> 
<res-auth>Container</res-auth> 

пружинно-context.xml:

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> 
    <property name="jndiName" value="java:comp/env/jdbc/welcome-kit"> 
</bean> 

, а также я добавил ojdbc.jar в котом/Lib

В web.xml

<resource-ref> 
    <res-ref-name>myDatasource</res-ref-name> 
    <res-type>javax.sql.XADataSource</res-type> 
    <res-auth>Container</res-auth> 
</resource-ref> 

В контексте весны приложения:

<!-- Define the JNDI datasource --> 
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> 
    <property name="jndiName" value="java:comp/env/myDatasource" /> 
</bean>
