CANNOT CREATE JDBC DRIVER OF CLASS

I was testing out springframework's jdbc with apache's dbcp when I came across the exception Cannot create JDBC driver of class 'oracle.jdbc.driver.OracleDriver' for connect URL 'jdbc:ORACLE:thin:localhost:1521:orcl' My configuration looked like this below

 <bean id="dataSource" 
       class="org.apache.commons.dbcp.BasicDataSource" 
	   destroy-method="close">  
	<property name="driverClassName" value="${jdbc.driverClassName}"/>
	 <property name="url" value="${jdbc.url}"/>  
	<property name="username" value="${jdbc.username}"/>  
	<property name="password" value="${jdbc.password}"/>  
</bean>

When I used spring DriverManagerDataSource class i was able to access the oracle instance with the same configuration.

<bean id="dataSource" 
      class="org.springframework.jdbc.datasource.DriverManagerDataSource">  
	<property name="driverClassName" value="${jdbc.driverClassName}"/>
	<property name="url" value="${jdbc.url}"/>  
	<property name="username" value="${jdbc.username}"/>  
	<property name="password" value="${jdbc.password}"/>  
</bean>

This was strange to me. After a night's rest, I was feeling refreshed for the morning to tackle this strange exception when I thought about case sensitivity. So I change my connection URL from jdbc:ORACLE:thin:localhost:1521:orcl to this jdbc:oracle:thin:localhost:1521:orcl and everything just worked fine. I guess apache's dbcp was a little sensitive.
