There is no code attribute in a method that is not native or abstract in the javax / faces / webapp / class file FacesServlet compilation error

Question

I am using eclipse Indigo and Tomcat 6.0.3 and JSF 2.0.

I work from this example, but I get these errors at runtime:

java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/faces/webapp/FacesServlet at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631) at java.lang.ClassLoader.defineClass(ClassLoader.java:615) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at org.apache.catalina.loader.WebappClassLoader.findClassInternal(WebappClassLoader.java:2818) at org.apache.catalina.loader.WebappClassLoader.findClass(WebappClassLoader.java:1159) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1647) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1526) at org.apache.catalina.startup.WebAnnotationSet.loadApplicationServletAnnotations(WebAnnotationSet.java:108) at org.apache.catalina.startup.WebAnnotationSet.loadApplicationAnnotations(WebAnnotationSet.java:58) at org.apache.catalina.startup.ContextConfig.applicationAnnotationsConfig(ContextConfig.java:297) at org.apache.catalina.startup.ContextConfig.start(ContextConfig.java:1078) at org.apache.catalina.startup.ContextConfig.lifecycleEvent(ContextConfig.java:261) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:142) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4612) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:799) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:779) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:601) at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:943) at org.apache.catalina.startup.HostConfig.deployWARs(HostConfig.java:778) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:504) at org.apache.catalina.startup.HostConfig.check(HostConfig.java:1385) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:306) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:142) at org.apache.catalina.core.ContainerBase.backgroundProcess(ContainerBase.java:1389) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1653) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1662) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.run(ContainerBase.java:1642) at java.lang.Thread.run(Thread.java:680) 

I added all banks javaee-web-api , javax.faces-api depending on maven:

My perception is correct. This is a problem with the jar file. You have not put the correct JSF jar file in your classpath.

  <dependency> <groupId>javax.faces</groupId> <artifactId>javax.faces-api</artifactId> <version>2.1</version> </dependency> 

Replace the dependency above with the following dependency:

 <dependency> <groupId>org.glassfish</groupId> <artifactId>javax.faces</artifactId> <version>2.1.13</version> </dependency>
