Attributo Codice assente nel metodo che non è nativo o astratto nel file di classe javax/faces/webapp/errore FacesServlet nella compilazione

Question

Uso eclipse Indigo e Tomcat 6.0.3 e JSF 2.0.

sto lavorando da this esempio ma ottengo questi errori in fase di esecuzione:

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

Answer 1

La mia percezione è giusto . Questo era un problema con il file jar. Non hai inserito il file jar JSF corretto nel classpath.

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

Sostituire sopra dipendenza con le seguenti dipendenze:

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