404错误：“原始服务器找不到目标资源的当前表示形式”。我该怎么办？

Question

我已经仔细阅读了我能找到的所有Stack Overflow帖子，并通过Google解决了这个问题，但无济于事。我已经在IntelliJ中建立了一个Maven项目。

当我尝试在浏览器上访问localhost：8090时，出现404错误：

  

原始服务器找不到目标资源的当前表示，或者不愿意透露其存在。

提供视觉图像。

这是工件设置：

这是Tomcat设置：

这是网址：

http://localhost:8090/json/product/ping

这是服务代码：

package com.project.rest;
import com.project.dao.OracleJDBC;
import com.project.product.FiftyInFifty;
import com.project.product.FsiProductLine;
import com.project.product.HHSProductLine;
import com.project.product.WrapProductLine;

import javax.ws.rs.*;
import javax.ws.rs.core.Response;
import java.util.Date;

@Path("/json/product")

public class JSONService {

    private FsiProductLine fsi = new FsiProductLine();
    private WrapProductLine wrap = new WrapProductLine();
    private HHSProductLine hhs = new HHSProductLine();
    private DalimGetPropertyValues properties = new 
    DalimGetPropertyValues();

    @GET
    @Path("ping")
    public String getServerTime() {
        System.out.println("RESTful Service 'DalimRestService' is running 
==> ping");
        return "received ping on " + new Date().toString() + "; environmen 
: " + properties.getEnvironemnt();
}}

这是我的web.xml文件：

    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>

</servlet>
<servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

这是我的POM文件：

我目前已将Tomcat设置为端口8090。我知道这应该很简单，但是无论我做什么，我似乎都无法使它正常工作。
