Hi,
I have one simple question:
Assume there are an entity bean A and two users (clients) U1 and U2. U1
finds the bean A with ejbFindByPrimaryKey(PK). He intends to update the
data represanted by bean A.
How can U2 be informed that bean A will currently be updated by another
user (must U1 do a ORA SELECT FOR UPDATE in the ejbFind.. method see
above)? U2 should be able to read the data but he has to know that he
cannot change the data (He is reading old data). If I use isolation
level "TRANSACTION SERIALIZABLE" then U1 won't be able to read the data,
will it ?
Any help will be appreciated
