I’ve read @EJB in @ViewScoped managed bean causes java.io.NotSerializableException, but my state saving setting is server.

Here is what I have:

I know I can workaround this by declaring PersonFacade as transient and use JNDI to get EJB reference after recontruction, but I really dislike this approach.

Is it possible that Glassfish 3.1.1 provides non-serializable EJBs? Is there a way to use @EJB and @ViewScoped together?

update:
i found that this is a MyFaces related issue, all is working fine using mojarra

🙂 I had the same problem: https://issues.apache.org/jira/browse/MYFACES-3581

David Blevins over at the Apache TomEE helped me a log a bug and patch for MyFaces. The problem was generated proxy classes aren’t on the classloader path for their deserializer.

A workaround is to set this web-app param to false: org.apache.myfaces.SERIALIZE_STATE_IN_SESSION
