Hi all,

I am trying to create a Database Manager page which shows the database details on page load and updates the database settings when the user press submit

I followed this tutorial and set the database settings in properties file.

I managed to update the database settings in properties file programmatically. When I retrieved the database settings using the following code

DriverManagerDataSource databaseSource = (DriverManagerDataSource)context.getBean("dataSource");
databaseSource.getUsername();

I managed to get the old value and unable to get the new value

This is the mapping in applicationContext.xml file

<bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    <property name="location">
        <value>classpath:/bundle/database.properties</value>
    </property>
</bean>

<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">

    <property name="driverClassName" value="${jdbc.driverClassName}" />
    <property name="url" value="${jdbc.url}" />
    <property name="username" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />
</bean>

I checked the properties file and found it to be updated with the latest input.

What am I missing?

Thanks in advance

P.S I am using JSF1.2 with Spring 3

Update

Just making my requirement simple. I am creating a setparate dbsettings page, so that when user wishes to connect to different database he/she can just enter the details in dbsettings page and connect
