I have created one EJB project, one Dynamic web project and for packaging EAR project with JBoss 7.0.0 Final. In JPA as a persistence provider i am taking EclipseLink. after deploying this is throwing Runtime Exception that is failed weld services and missing Validator and ValidatorFactory : - unstasfied dependencies. while I am using Hibernate as Persistence Provider it's working fine. How to fix this problem. Even I made EclipseLink module and also adding the jar in build path. I am using Eclipse as IDE and working platform is Linux.
