> 1) concurrent access from clients, that means shared

You still get this if your application is designed
such that Session beans talk to DAOs which handle
database access.
> 2) transaction and security stuff
Currently most (if not all) app servers rely on the
database resource managers for handling txn isolation,
which you can still avail of from DAOs by using the
same txn managers and resource managers.
> 3) abstraction from database
DAOs will provide you the same level of abstraction as
entity beans without adding the remoting code, and
container redirections.
> But do NEVER access entity beans from the web tier.
Could'nt agree more.
