我正在使用 eclipse Indigo 和 Tomcat 6.0.3 和 JSF 2.0。

我正在使用此示例，但在运行时出现这些错误：

我在 maven 依赖项中添加了所有javaee-web-api, javax.faces-apijar：

我的认知是对的。这是jar文件问题。您没有在类路径中放置正确的 JSF jar 文件。

  <dependency>
            <groupId>javax.faces</groupId>
            <artifactId>javax.faces-api</artifactId>
            <version>2.1</version>
  </dependency>

用以下依赖项替换上述依赖项：

<dependency>
        <groupId>org.glassfish</groupId>
        <artifactId>javax.faces</artifactId>
        <version>2.1.13</version>
 </dependency>
