Question

Spring java- quartz schedular application

I want to load .property file dynamically passed throw program parameter instead of context:property-placeholder in spring context, how can i achieve this task, any help appreciated...

I am manually loading and refreshing spring context from main java file as illustrate by following code.

rootContext = new ClassPathXmlApplicationContext();
rootContext.setConfigLocation("abc-configuration.xml");
rootContext.refresh();

In spring configuration i have context property place holder as follows which i want to from code.

<context:property-placeholder location="classpath:lnRuntime.properties"/>

i am using place holders in spring context and java file using spring EL as follows

<bean id="dataSource" 
class="org.springframework.jdbc.datasource.SingleConnectionDataSource">
        <property name="driverClassName" value="net.sourceforge.jtds.jdbcx.JtdsDataSource"/>
        <property name="url" value="${dataSource.url}"/>
    </bean>
