Tomcat 7 ClassNotFoundException：org.glassfish.jersey.servlet.ServletContainer

Question

我正在尝试从带有 Jersey 2.13、JDK 8 的 OS X 10.10 上的 apache 7.0.57 运行 RESTful 服务。我已经部署了 Apache，它可以正常启动。我编写了一个简单的 RESTful 服务并将其部署到 WEB-INF/classes。 web.xml 已配置。但是，当我尝试启动 tomcat 时，出现以下错误的 restful 资源错误

SEVERE: Servlet /resttest threw load() exception

java类

package org.sample.resources;

import javax.ws.rs.Path;
import javax.ws.rs.GET;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/xyz")
public class TestGet {

  @GET
  @Produces(MediaType.TEXT_PLAIN)
  public String sayHello() {
      return "Hello Jersey";
  }
}

我什至已将 jersey-container-servlet-core.jar 的内容提取到 WEB-INF/classes 目录，但重新启动时仍然出现相同的错误。

任何指针？

在资源管理器中手动将所有 Jersey jar 文件复制到 WEB-INF/lib；当我遇到同样的问题并且对我有用时，我就这样做了。
