From source file:com.talvish.tales.services.ServiceHost.java

/**
 * The standard Java main entry point, which in this case will
 * instantiate and run the service and then wait for it to be 
 * shutdown.//from ww  w  .jav a  2s. c  om
 * @param theArgs the arguments containing the start-up or override parameters
 * @throws Exception any potential uncaught exception
 */
public static void main(String[] theArgs) throws Exception {
    logger.info("Service host is initializing.");

    ConfigurationManager configurationManager = instantiateConfiguration(theArgs);
    Class<? extends Service> serviceClass = loadServiceClass(configurationManager);
    Service serviceInstance = instantiateService(serviceClass);

    // now we have the service create 
    // so let's get it running and wait
    // for it to finish
    serviceInstance.start(configurationManager);
    serviceInstance.run();
    serviceInstance.stop();
