Proper use of spring ContextLoader subclass for testing

For integration tests for my spring application with junit, I will subclass org.springframework.test.context.ContextLoaderbecause I want to use an existing one XmlWebApplicationContextto connect my test class as follows:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=MyContextLoader.class)
@Transactional
public class MyTest {
    @Autowired
    public AccountDao accountDao;
}

The implementation of my ContextLoader is as follows:

Public class MyContextLoader implements ContextLoader {

    @Override
    public String[] processLocations(Class<?> clazz, String... locations) {
        return locations;
    }

    @Override
    public ApplicationContext loadContext(String... locations) throws Exception {
        try {
            // Start Embedded Tomcat
            EmbeddedTomcat tomcat = new EmbeddedTomcat("mas", 8080);
            tomcat.launch();

            Context rootContext = tomcat.getRootContext();
            ContextLoaderListener contextLoaderListener = (ContextLoaderListener) rootContext.getApplicationLifecycleListeners()[0];
            XmlWebApplicationContext context = (XmlWebApplicationContext) contextLoaderListener.getContext();


            GenericApplicationContext c = new GenericApplicationContext(context);
            AnnotationConfigUtils.registerAnnotationConfigProcessors(c);

            //context.refresh();
            //context.registerShutdownHook();

            return context;
        }
        catch(Exception e) {
            e.printStackTrace();
            throw new RuntimeException(e);
        }   
    }   
}
