1) Do you mean that this application updating the database is running outside the
EJB server, i.e. the "Bean" you mention is not an EJB ? right ?

2) What do you mean by "look at the entity bean attribute values with simple SQL
queries" ? Is it still accessing the database outside the EJB server ?
If answers to 1) and 2) are "yes", we come back to a discussion between Philippe
and Markus on this list, about accessing the database both from the EJB server and
from an external application. However in your case the solution seems simple, i.e.
if you perform your getXXX() method on your entity bean within a transaction
(starting after the one performed by your "management bean" for updating the
database), the data should be read from the database and you should get the
up-to-date values ... for example try to set the transactional attributes of your
getXXX methods to "requires_new" in the deployment descriptors ...
