【问题描述】：

我正在使用 netbeans 和 apache tomcat 来运行 Web 应用程序。我不断收到此错误：

这是我的 POM：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.success</groupId>
  <artifactId>share-wheels</artifactId>
  <packaging>war</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>share-wheels Maven Webapp</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>

      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <finalName>share-wheels</finalName>
  </build>
</project>

这里有什么问题？？..

编辑：
当我将以下内容添加到 thw pom 文件时，会出现此问题：

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
</dependency>

这是为什么？我需要 HttpServletRequest 的这种依赖关系。我该如何解决这个问题？

【问题讨论】：

  • 尝试从您正在部署的 WAR 中删除 servlet 和 JSTL 类。
  • 哪个 servlet？.. 它在哪里（不在 pom 中）？这是一个新项目。怎么去掉？

【解决方案1】：

右键单击..清理并构建！ 我在 netbeans 中开发 Spring Web MVC 应用程序时遇到了这个问题。通常清理和构建工作

【讨论】：

    【解决方案2】：

    使用&lt;scope&gt;provided&lt;/scope&gt; 表示您需要编译该工件，但不要在您的战争中使用它。

    <dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>

    【讨论】：

    • 为什么我在战争中不需要它？
    • 因为这个jar的相关部分（servlet等）已经包含在你的服务器中了。
    • 那又怎样？ :) 当我再次添加它时会发生什么？为什么会坏掉？
    • servlet 规范允许容器拒绝非法定义，例如属于java.... 命名空间的类。这些 API 的作用。
    【解决方案3】：

    我遇到了与 Naor 相同的部署失败。我的 Tomcat webapps 文件夹没有默认 Tomcat dist 附带的管理器模块（我已删除！）。因此，当 NetBeans 尝试在 Web 容器 (Tomcat) 上进行部署时，它会失败，因为没有管理器模块。恢复管理器模块可以解决错误消息。

    【讨论】：

    • 我也遇到了同样的问题，您可以通过确保 Tomcat 中的管理器模块正确来轻松解决它。即使管理器模块存在，也要确保它具有默认管理器模块的所有文件。
