java.lang.ClassFormatError：类文件javax / faces / FacesException中不是本机或抽象的方法中的缺少Code属性

Question

I am trying to run JSF project with tomcat and eclipse.

I have just implemented simple page with HelloWorld. When I try to start server its throwing following error:

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

I have included following libraries in classpath:

• 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

Please help me to solve this error.

Answer 1

After some analysis, I found that I have added libraries from wrong place. I have also removed extra libraries from build path.

Following is the final list of dependency and it worked for me:

<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>

Thanks.
