Hi,
    I have spring mvc enabled web apps (20+ web apps) packaged as an EAR deployment. All my spring mvc related jar's are in  my EAR/lib, i'm using SpringServletContainerInitializer (implementation of ServletContainerInitializer ) code as follows
{code}
@HandlesTypes(WebApplicationInitializer.class)
public class SpringServletContainerInitializer implements ServletContainerInitializer {

	@Override
	public void onStartup(Set<Class<?>> webAppInitializerClasses, ServletContext servletContext)
			throws ServletException {

		List<WebApplicationInitializer> initializers = new LinkedList<WebApplicationInitializer>();

		if (webAppInitializerClasses != null) {
			for (Class<?> waiClass : webAppInitializerClasses) {
				// Be defensive: Some servlet containers provide us with invalid classes,
				// no matter what @HandlesTypes says...
				if (!waiClass.isInterface() && !Modifier.isAbstract(waiClass.getModifiers()) &&
						WebApplicationInitializer.class.isAssignableFrom(waiClass)) {
					try {
						initializers.add((WebApplicationInitializer) waiClass.newInstance());
					}
					catch (Throwable ex) {
						throw new ServletException("Failed to instantiate WebApplicationInitializer class", ex);
					}
				}
			}
		}

		if (initializers.isEmpty()) {
			servletContext.log("No Spring WebApplicationInitializer types detected on classpath");
			return;
		}

		AnnotationAwareOrderComparator.sort(initializers);
		servletContext.log("Spring WebApplicationInitializers detected on classpath: " + initializers);

		for (WebApplicationInitializer initializer : initializers) {
			initializer.onStartup(servletContext);
		}
	}

}

{code}

But the @HandlesTypes(WebApplicationInitializer.class) are not getting detected from the EAR/lib

Even i have tried adding the extracted the SPI from spring-web jar and added inside my war's WEB-INF/lib as a jar
 WEB-INF/lib/web-init-spi.jar which contains
META-INF/services/javax.servlet.ServletContainerIntializer file with org.springframework.web.SpringServletContainerInitializer as an entry. This time its detecting SpringServletContainerInitializer but not detecting what defined in @HandlesTypes

Its only working If i package all those spring mvc jars inside WEB-INF/lib then everything started working. 

I have no idea this is how the servlet specification works or its a wildfly issue but i see it as a problem for those who depends on Wildfly or similar EE Servers with an EAR deployment structure.
