---------------------------------
    Description: 
Hello.
I use a spring-ignite in my application. When using ServiceGrid I noticed a feature.
I created the following class for the ServiceGrid:

{code:java}
public class SimpleService implements Service, ApplicationContextAware {
    private ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException
{
        this.applicationContext = applicationContext;
    }

    @Override
    public void init(ServiceContext serviceContext) throws Exception {
        if (applicationContext == null) {
            System.out.println("ApplicationContext is null");
        }
    }

    @Override
    public void execute(ServiceContext serviceContext) throws Exception {

    }

    @Override
    public void cancel(ServiceContext serviceContext) {

    }
}
{code}
