Проблема с классом ServletExtension

Question

Я реализовал механизм SevletExtention для подбора api. Код подобен

public class MyServletExtentionClass implements ServletExtension{ 

    @Override 
    public void handleDeployment(final DeploymentInfo deploymentInfo, final ServletContextImpl servletContext) { 
     deploymentInfo.addInitialHandlerChainWrapper(new HandlerWrapper() { 

      @Override 
      public HttpHandler wrap(HttpHandler handler) { 
       return Handlers.path() 
         .addPrefixPath("/", handler) 
         .addPrefixPath("/hello", new MyHandler()); 
      } 
     }); 

    } 
} 

также я добавил файл io.undertow.servlet.ServletExtension под META_INF/услуг с содержанием com.handler.MyServletExtentionClass

Но когда я развернуть войну файл в wildfly. Я получаю исключение, как показано ниже.

попробовать это

... 
import io.undertow.servlet.ServletExtension; 
import javax.enterprise.inject.spi.Extension; 

public class MyServletExtentionClass implements Extension, ServletExtension { 
....
