entity bean versus session bean for BMP

Hi,

I have two needs
a) cache reference (lookup) semi-static data
b) execute my own SQL statements

So far for a) entity beans seems to work fine. I assume will have to
play with the isolation levels of methods in order to allow for
multiple concurrent readers.

For b) I have been using stateless session beans, which connect to the
database via JDBC and execute SQL as needed.

However this seems like a lot of beans being created unecessarily.

What if I switched those to Entity beans - which have no instance data
but which execute the SQL using local method variables only.

Would that work - can I make those methods Read Uncommitted forcing all
the transaction management to be handled by the database.

Does this make sense?

thanks

Tim
