How to get properties in JSP files using spring mvc 3

I am very new to spring mvc 3 annotation based application. I have two properties files - WEB-INF\resources\general.properties, WEB-INF\resources\jdbc_config.properties

Now I want to configure them through spring-servlet.xml. How I can achieve this?

In general.properties,

label.username = User Name:
label.password = Password:
label.address = Address:

...etc jdbc_config.properties,

app.jdbc.driverClassName=com.mysql.jdbc.Driver
app.jdbc.url=jdbc:mysql://localhost:[port_number]/
app.jdbc.username=root
app.jdbc.password=pass

---etc

If I want to get label.username and app.jdbc.driverClassName in my jsp page, how do I code for them?

I also want to access these properties values from my service. How to get these property values using respective keys in method level in service class or controller class?
