com.sun.enterprise.config.ConfigException: Failed to load deployment descriptor for: dokumanyonsist
cause: Invalid ejb jar [jboss-seam.jar]: it contains zero ejb. 
Note: 
1. A valid ejb jar requires at least one session, entity (1.x/2.x style), or message driven bean. 
2. EJB3+ entity beans (@Entity) are POJOs and please package them as library jar. 
3. If the jar file contains valid EJBs which are annotated with EJB component level annotations (@Stateless, @Stateful, @MessageDriven), please check server.log to see whether the annotations were processed properly.
