Properties not being substituted in applicationContext.xml - spring

Question

I'm facing a very weird issue. I'm tring to configure the properties of my datasource declared in my spring applicationcontext.xml file via a PropertyPlaceholderConfigurer class. The application context file looks like this:-
<?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:context="http://www.springframework.org/schema/context"

<property name="password" value="${db.password}"/>
</bean>
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource"/>
</bean>
</beans>
I have tried using the context:property-placeholder tag as well but it doesn't seem to have any effect. The above mentioned properties files are deployed successfully under the WEB-INF/classes directory as well.
For some reason, the spring container is able to load the properties files(checked with an invalide properties file and it throws a FNF exception) but not able to substitute the property placeholders with their values.
I'm using a tomcat 7 WS with the CATALINA.BASE pointing to my runtime. Has anybody faced this issue before? Any solutions?

Answer 1

Take that leading slash out of the values:
<value>classpath:activemq.properties</value>
<value>classpath:jdbc.properties</value>

Answer 2

Try the following configuration.
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:activemq.properties</value>
<value>classpath:jdbc.properties</value>
</list>
</property>
</bean>
The issue is likely the fact that you even named the PropertyPlaceholderConfigurer bean. Most Spring internal beans are not given an id, as the framework is configured to look for certain bean names, and often the default bean name is the auto-generated name based on the object type.
