datasource property resolution error
I am trying to load properties into the datasource via a property file. The spring documentation says this will work, but it is failing for me.
Code:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
properties are set as:
Code:
jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@localhost:1521:xe
jdbc.username=system
jdbc.password=system
Getting the following error:
Code:
org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class '${jdbc.driver}'

PropertyPlaceHolderConfigurer
Marten, Thanks for your reply. I should have included that configuration in the post above.
Code:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<value>classpath:myApplication.properties</value>
</property>
</bean>
I have another application, configured the same way, that use properties from a property file. It exhibits no problems. I do not configure a datasource in that application. It seems to be linked to the datasource only.
