Using variables in applicationcontext.xml

[joatmon]

I'm sorry if this is the wrong forum. I've seen references in the user documentation to using "variables" in the applicationcontext.xml file. There are places where ${somevalue} is entered for the value of an element and that value appears to get pulled from another file. Could someone give me some information on how to do this in my own app? I've looked around, but can't seem to find how this is being accomplished. Thanks for helping a newbie!

Thanks,

	<!-- replace $&#123;&#125; with properties file values -->
	<bean id="propertyConfigurer"
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="location">
			<value>classpath&#58;database.properties</value>
		</property>
	</bean>
	
	<!-- data source -->
	<bean id="dataSource"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName">
			<value>$&#123;db.driverName&#125;</value>
		</property>
		<property name="url">
			<value>$&#123;db.url&#125;</value>
		</property>
		<property name="username">
			<value>$&#123;db.username&#125;</value>
		</property>
		<property name="password">
			<value>$&#123;db.password&#125;</value>
		</property>
	</bean>

add propertyConfigurer to your bean defenition xml and then,you can put your ${somevalue} to database.properties that under classpath
