tomcat - javax.naming.NameNotFoundException : Name > [com] is not bound in this Context. 无法找到 [com]

Question

我正在从动态 Web 项目类型开发一个简单的 Jersey Web 服务，遵循 this教程。到目前为止，我有以下代码:

ServiceStatus.Java(在包 au.com.biting.bolat.status 中)

package au.com.biting.bolat.status;

import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;

@Path("/v1/status")
public class ServiceStatus {

    @GET
    @Produces(MediaType.TEXT_HTML)
    public String returnTitle() {
        return "<p>Java Web Service</p>";
    }

}

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>au.com.biting.bolat</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>


  <servlet>
    <servlet-name>Jersey REST Service</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
      <param-name>com.sun.jersey.config.property.packages</param-name>
      <param-value>au.com.biting.bolat</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Jersey REST Service</servlet-name>
    <url-pattern>/api/*</url-pattern>
  </servlet-mapping>
  </web-app>

当我在 tomEE 中运行此服务时，根路径 ( http://localhost:8080/au.com.biting.bolat/ ) 工作正常，但路径 http://localhost:8080/au.com.biting.bolat/api/v1/status 出现以下错误:

我尝试了几种修复方法，包括清理和构建项目、从头开始构建项目并检查了 this similar question ，但错误是无关的。这里有什么问题？

我不知道你用的是哪个版本的 Jersey ，所以我考虑最后一个。尝试更改 web.xml 中某些属性的名称，因为您使用的是旧的，教程有点旧:

...
<servlet>
    <servlet-name>Jersey REST Service</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>au.com.biting.bolat</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
...
