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

Question

I want to use Mojarra 2.1 with Tomcat 7, so I added following dependencies in my pom file:

       com.sun.faces

        

Answer 1

Change:

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

To:

 <dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.faces</artifactId>
    <version>2.1.6</version>
 </dependency>

Answer 2

I traded to glassfish-embedded-all and resolved this.

    <dependency>
        <groupId>org.glassfish.main.extras</groupId>
        <artifactId>glassfish-embedded-all</artifactId>
        <version>3.1.2.2</version>
        <scope>provided</scope>
    </dependency>

Answer 3

I have the same problem as you and found out that change from servlet-api to javax.servlet.api will fix the problem. Hope this help. Please note that, I am using Juno Eclipse, Tomcat 7, Dynamic Web Module 3.0, and JDK 1.7.

<dependency>
  <groupId>com.sun.faces</groupId>
  <artifactId>jsf-api</artifactId>
  <version>2.1.13</version>
</dependency>
<dependency>
  <groupId>com.sun.faces</groupId>
  <artifactId>jsf-impl</artifactId>
  <version>2.1.13</version>
</dependency>
<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.0.1</version>
</dependency>

Answer 4

I have the same problem, and it seams somehow to

<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>

or

<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>

after setting them to scope provides (or delete them at all when you start an server in maven test) it starts working for me.

@See this Blog: java.lang.ClassFormatError : Absent Code attribute in method that is not native or abstract in class file … - It discuss the problem for javax.persistence.GenerationType but I think you and I hit the same problem.
