consider transactions using ejb's from
2 diff clients acessing the same server
(weblogic) on same table rows. now if
this does go on without a lock , after fetching the rows from the db the client who updated the db first will
not see his changes on the screen!, as
what will be read will be the last updated value. how do we avoid this situation?
