Re: Are Entity Beans(CMP/BMP) really necessary???

[John Harby]

Yes, basically but unfortunately if say a stored procedure or some
non-container managed process is also changing data in the table, this will
fail. From the feedback I hear in the field, setting db-is-shared for the
*whole* db is not realistic, many customers have something else going on but
more may be able to use a "table-is-shared" for a CMP entity since this
leaves their other tables free for non-container managed processes.
Otherwise we have to somehow take into account that external processes may
change the data, correct?
