Question

我试图在我的tomcat 7上设置一个新的jsf 2项目，我第一次访问我的webapp时遇到了这个错误。

知道原因是什么吗？

Answer 1

找到了这个问题的原因。这是一个依赖性问题。

之前：

<dependency>
    <groupId>com.sun.faces</groupId>
    <artifactId>jsf-api</artifactId>
    <version>2.1.0-b11</version>
</dependency>
<dependency>
    <groupId>javax.faces</groupId>
    <artifactId>jsf-impl</artifactId>
    <version>1.2</version>
    <type>jar</type>
    <classifier>NIGHTLY_20060227</classifier>
</dependency>

似乎问题源于我将com.sun.faces和javax.faces工件结合起来。

用以下内容替换上述问题即可解决：

<dependency>
    <groupId>javax.faces</groupId>
    <artifactId>jsf-api</artifactId>
    <version>2.0.3</version>
    <type>jar</type>
    <scope>compile</scope>
</dependency>
<dependency>
    <groupId>javax.faces</groupId>
    <artifactId>jsf-impl</artifactId>
    <version>2.0.3</version>
    <type>jar</type>
    <classifier>NIGHTLY_20060227</classifier>
    <scope>compile</scope>
</dependency>

当然，别忘了重新启动tomcat： - ）

上述设置仍然存在问题。正确的位于here，工作正常！
