java.lang.ClassFormatError : Absent Code attribute in method that is not native or abstract in class file javax/faces/FacesException

Question

我正在尝试使用 tomcat 和 eclipse 运行 JSF 项目。

我刚刚用 HelloWorld 实现了简单的页面。当我尝试启动服务器时，它抛出以下错误:

SEVERE: Error configuring application listener of class org.apache.catalina.deploy.ApplicationListener@2fbb7466

我已在类路径中包含以下库:

• javae-api-6.0.jar
• javae-web-api-6.0.jar
• javax-servlet-api-3.1.0.jar
• jsf-api-2.1.jar
• jsf-impl-1.2.jar
• jSTL-1.2.jar
• primefaces-5.0.jar

请帮我解决这个错误。

Answer 1

经过一些分析，我发现我从错误的位置添加了库。我还从构建路径中删除了额外的库。

以下是最终的依赖项列表，它对我有用:

<dependencies>
<dependency>
    <groupId>com.sun.faces</groupId>
    <artifactId>jsf-api</artifactId>
    <version>2.2.7</version>
</dependency>

<dependency>
    <groupId>com.sun.faces</groupId>
    <artifactId>jsf-impl</artifactId>
    <version>2.2.7</version>
</dependency>

<dependency>
    <groupId>org.primefaces</groupId>
    <artifactId>primefaces</artifactId>
    <version>5.0</version>
</dependency>

谢谢。
