#Resource dataSource mappedName - overriding to test in non JNDI env - spring

Question

I have an existing service bean which we deployed in Jboss. Unfortunatly it's dataSource reference is configured to inject the datasource reference via the "mappedName" lookup of the JNDI Service.
#Resource(name = "dataSource", mappedName = "java:/OracleDS")
private DataSource dataSource = null;
I want to test the bean in a non JNDI env. I expected to get this exception when i run in a non JNDI env.
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating
bean with name 'myService': Injection of resource fields failed; nested exception
is org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean
definition with name 'java:/OracleDS' defined in JNDI environment: JNDI lookup
failed; nested exception is javax.naming.NoInitialContextException: Need to
specify class name in environment or system property, or as an applet parameter,
or in an application resource file: java.naming.factory.initial
I realise the quickest way to fix this is to dropped the mappedName restriction, since then the production or test spring context can define the datasource. But in the case that i can't do this. Is there a way to define an InitialContext via a test spring context to avoid the exception above.

I did some more reading on SimpleNamingContextBuilder and came up with this context setup for my test case. The trick being to use the MethodInvokingFactoryBean to ensure the bind() method is called.
<bean id="jndiContext" class="org.springframework.mock.jndi.SimpleNamingContextBuilder" factory-method="emptyActivatedContextBuilder"/>
<bean id="invokingFactoryBean"
class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject">
<ref local="jndiContext" />
</property>
<property name="targetMethod">
<value>bind</value>
</property>
<property name="arguments">
<list>
<value>java:/OracleDS</value>
<ref bean="dataSource" />
</list>
</property>
</bean>
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${datasource.driverClassName}" />
<property name="url" value="${datasource.url}" />
<property name="username" value="${datasource.username}" />
<property name="password" value="${datasource.password}" />
</bean>
