JPA/JTA 컨테이너 관리 지속성이 유지되지 않습니다.

Question

websphere 컨테이너 관리 지속성을 사용하고 있지만, EntityManager.persist는 Derby 데이터베이스에 삽입/저장하지 않습니다.

@TransactionManagement(TransactionManagementType.CONTAINER) 
    @Stateless 
    @SessionScoped 
    public class claimSessionBean implements ClaimSessionI { 

    public claimSessionBean() { 
     } 

    @PersistenceContext(name="lab01Web") 
    private EntityManager em; 

    public void createclaimHeader(ClaimHeader claimHeader) { 
      System.out.println("creating clm"); 
      em.persist(claimHeader); 

    }

ClaimHeader : ClaimHeader : 아래

내 세션 빈/DAO입니다 패키지 실체
