Answer / vamsee

As both are different technologies, they vary in mapping to
Data bases. Ejb's uses service of J2EE container to talk to
DB's but is not. It is ORM model which directly talk to the
DB objects. Hibernate reduces the level of complexity to
map the DB.

how can u integrate ejb and hibernate? How can u call hibernateDAO methods in session bean? ..

Answer / 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.
