Question

I’m creating my Spring context inside a static main method with

return new ClassPathXmlApplicationContext("applicationContext.xml");

Inside applicationContext.xml I’m wiring one of my beans with

<bean id="dataSource" 
    class="org.springframework.jdbc.datasource.SingleConnectionDataSource">
    <property name="driverClassName">
        <value>${db.driverclassname}</value>
    </property>
    ...
</bean>

I’ve got a .properties file on my class path that contains the value db.driverclassname.

Unfortunately I’m getting the following error:

Property 'driverClassName' threw exception; 
    nested exception is java.lang.IllegalStateException: 
        Could not load JDBC driver class [${db.driverclassname}]

What am I doing wrong? I’m using Spring 2.5.5

Don’t you need a PropertyPlaceholderConfigurer ?

e.g.

<bean id="propertyConfigurer"      
      class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
   <property name="location">
      <value>classpath:project.properties</value>
   </property>
</bean>

This article details usage.
