我想在Tomcat 7中使用Mojarra 2.1,所以我在我的pom文件中添加了以下依赖项:

<dependency>
       <groupId>com.sun.faces</groupId>
       <artifactId>jsf-api</artifactId>
       <version>2.1.2</version>
     </dependency>

     <dependency>
       <groupId>com.sun.faces</groupId>
       <artifactId>jsf-impl</artifactId>
       <version>2.1.2</version>
     </dependency>

但是,当我尝试启动Tomcat时,我遇到以下异常:

我有两个Web应用程序(web-module1.war和web-module2.war),我想使用Web片段(web-core.jar)进行常见的servlet声明,如FacesServlet.

当我在web.xml中声明FacesServlet没问题,但是当我将此声明移动到web-fragment.xml时,我收到此错误:
