当尝试用Tomcat 8.5加载球衣类时出现此错误

我链接到代码的依赖项在下面

Web.xml条目是

<servlet>
                                <servlet-name>RESTFul servlet </servlet-name>
                                <servlet-class> org.glassfish.jersey.servlet.ServletContainer </servlet-class>

                                        <param-value>com.mypkg.MyClass</param-value>

<servlet-mapping>

                        <url-pattern> /rest/* </url-pattern>
                   </servlet-mapping>

配置类是

package com.mypkg
import org.glassfish.jersey.server.ResourceConfig;
public class MyClass extends ResourceConfig 
{
     public MyClass()
     {
          System.out.println("Successfully Registered");
     }
}

非常感谢您的帮助。谢谢。
