Answer Posted / guest
hibernate used to perform OR(object relational) mapping.it
is alternate to DAO .
servlets--->ejbSEssionbean(to store businesslogic)--->ejb
entity bean(to maintain persistence logic)here we use
hibernate instead of entity bean.
the above said is the integration procedure to separate
businesslogic from perssitence logic.
to call DAO methods in session bean normally we use
callback methods ejbcreate(),ejbload() to clear previous
datas in database,ejbstore()to store new datas using
primarykey value.ejbsetSessionContext() to initiate the
call.
