[appengine-java] Problem with JDO 1-1 mapping

[Kamlesh]

 When ever I try to save object of class UserPrincipalCredentials ,
using persistancemanager (see snippet below) , the child property
userProfile does not get saved. can anyone please review my
annotations and tell me what could be wrong with them ?

Code for saving Operation
________________________________________________
        public UserPrincipalCredentials create(UserPrincipalCredentials
credentials) {
                final PersistenceManager pm = 
PMFProvider.get().getPersistenceManager
();
                try {
                        System.out.println("trying to save");
                        //final UserProfile profile = 
credentials.getUserProfile();
                        //profile.setLoginAccount(credentials);
                        pm.makePersistent(credentials);

                } finally {
                        pm.close();
                }

                System.out.println("New User Added....... ");
                System.out.println("UserName : " + credentials.getUserName());
                System.out.println("Password : " + credentials.getPassword());
                System.out.println("Role : " + 
credentials.getRoles().get(0).getRole
());
                System.out.println("Perm : "
                                + 
credentials.getRoles().get(0).getPermissions());
                System.out.println("Profile : " + credentials.getUserProfile()
                                + " , persistent ? : "
                                + 
JDOHelper.isPersistent(credentials.getUserProfile()));
                return credentials;
        }
