We have entity bean which is connected to database table.
This entity bean holds data of logged in user. Can we keep this entity bean in sesson?
Thanks.

You can store a handle for the entity bean into HttpSession.

Don't do it. It won't help. If you store the handle or the reference in the session you will STILL incur the same database lookup penalty whenever you access any of the fields because each lookup will be a new transaction!
Instead, create a ValueObject from the Entity data and store that in the HttpSession.
