在Tomcat上部署JSF戰爭時出現異常

Question

我擁有JSF war文件並將其部署到Tomcat8。但是，當我開始了，有以下情況除外：

23-Sep-2015 08:55:39.664 INFO [http-nio-4747-exec-15] org.apache.catalina.core.ApplicationContext.log HTMLManager: start: Starting web application '/jsfexample' 
23-Sep-2015 08:55:39.709 SEVERE [http-nio-4747-exec-15] org.apache.catalina.core.ApplicationContext.log FAIL - Application at context path /jsfexample could not be started

Answer 1

我在Tomcat的7有同樣的問題，我將完整的JSF Maven依賴解決它（我是缺乏jsf-impl）：

<dependency> 
    <groupId>com.sun.faces</groupId> 
    <artifactId>jsf-impl</artifactId> 
    <version>2.2.12</version> 
</dependency> 
<dependency> 
    <groupId>javax.faces</groupId> 
    <artifactId>javax.faces-api</artifactId> 
    <version>2.2</version> 
</dependency> 

我猜測Tomcat 8也一樣。
