hibernate - unidirectinal @OneToMany without join table -


i using hibernate. parent class company. company has many activities. need load activities when company loading. need save company , activities separately. in company class have:

@onetomany(fetch = fetchtype.eager, targetentity = activity.class) private set<activity> activityreuslts;

in activity not have join company table. when try run gives 

'ora-00972: identifier long' exception.

can't this? appreciate help.

i think when use target entity gives exception since wrong mapping. 

select this_.company_id y0_, this_.a ttempt_id y1_ mel_company this_  inner join mel_company_mel_company_activ ity_out_put activityre3_ on this_.company_id=activityre3_.mel_company_company_id , this_.attempt_id=activityre3_.mel_company_attempt_id   inner join mel_company_activity_out_put activityre1_  on activityre3_.activityreuslts_company_activity_re sult_id=activityre1_.company_activity_result_id.

according there 2 joins same activityresults. 1 wrong. 'mel_company_mel_company_activity_out_put'
