无论我做什么，TomCat7都会返回HTTP ERROR 404

标签： java eclipse jersey tomcat7 http-status-code-404

离开java多年之后（我迷失在.net的土地上，如果它有用的话）我现在发现自己处于一个＆＃34; java 7＆＃34;商店（我告诉他们不会改变）我试图按照http://www.mkyong.com/webservices/jax-rs/jersey-hello-world-example/的教程进行操作，无论我做什么，无论我做什么，tomcat7都会报告一个非常快的404错误

过去几天我一直在搜索这个 - 直到现在它一直是一个低优先级 - 而且我找不到任何可以帮助我的东西。我的同龄人都没有想到这一点。我没有防火墙，我使用的是我团队中的其他所有人。我尝试了很多东西，而且我发现的每一个搜索结果根本就没用。

我不知道该怎么做;我目前被迫使用Kepler版本的Eclipse，所以我需要在eclipse中使用tomcat7，因为这个问题我完全没有进展。

  • Eclipse：Kepler但是＆＃34;企业化＆＃34;我无法控制我们必须使用它。
  • Tomcat：Tomcat7

项目是在maven中生成的＆＃34; webapp＆＃34; archetype然后导入到eclipse中，我没有对该教程中的字母做过唯一的事情就是运行＆＃34; eclipse：eclipse在maven中我第一次这样做了它破坏了项目并创建了一个var-type maven / eclipse不理解的类路径（类型：4）所以我从头开始重新编写所有内容而不运行该命令，然后成功将其导入eclipse。

问题：我做错了什么？我该如何调试并帮助自己？

我认为tomcat通常有一个可用于帮助调试的管理器/ UI，但即使在查看了tomcat的文档之后，然后复制并粘贴他们说要用来启用它的配置，然后弹出tomcat服务并重新加载eclipse，无论我去哪个url / link，我仍然会得到404错误。

提前谢谢。

我得到的唯一日志如下：

我不确定它是什么，但我设法让一个简单的工作在pom中使用这些：

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-server</artifactId>
    <version>1.17.1</version>
</dependency>
<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-core</artifactId>
    <version>1.17.1</version>
</dependency>
<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-servlet</artifactId>
    <version>1.17.1</version>
</dependency>

更新我的web.xml以使用v1 xml配置：

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
    <display-name>REST Web Application Demo</display-name>
    <servlet>
        <servlet-name>jersey-serlvet</servlet-name>

        <!-- v1 -->
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>

        <load-on-startup>1</load-on-startup>
        <init-param>

            <!-- v1 Packages Reference -->
            <param-name>com.sun.jersey.config.property.packages</param-name>
            <param-value>com.example.app</param-value>

        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>jersey-serlvet</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>
</web-app>

但现在可悲的是，我现在得到了一个非常不同的例外：
