how to load properties file only once in enterprise application

This is the class which loads properties file which returns static instance;
**********************************************************************

public class LoadProperties {
	private static Properties properties = new Properties();

	
	public static Properties getProperties() {
		return properties;
	}

	
	public static void setProperties(
			Properties properties) {
		LoadProperties.properties = properties;
	}

}

This is Listener class mentioned in web.xml which can be read when server starts up;
**********************************************************************
public class LoadProperties implements ServletContextListener {

public void contextInitialized(ServletContextEvent arg0) {
		
		//Below properties placed in application server class path in server lib folder with compressed jar;
		InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("server.properties");
		
			
		LoadProperties.getProperties().load(inputStream);
		
				//value is printed successfully;
			System.out.println("LoadProperties.."+LoadProperties.getProperties().getProperty("type"));

		}

}

My requirement is How do we read this property(LoadProperties.getProperties().getProperty("type")) in EJB class without loading the properties file once again?because when we load this properties in WAR level we will get once instance of LoadProperties;I dont think same instance will not be propagated in EJB level as well.So Do i need to load same properties once again in EJB classes as well?

my EAR structure is like this;

APP.ear
lib--- jars -- server.properties related jar is placed in the application server class path not in this folder;
ejb.jar
web.war
