Hi! Does tomcat offer any mechanism for locking servlet executions?
So if one servlet does: - get 10 EUR from account 1 (read account 1 balance; substract 10; store new balance) - add 10 EUR to account 2 (...) How can I make sure no other servlet does (read account 1 balance; sustract 10; store new balance) at the same time and cause lost account money? The account data is in a database, accessed over hibernate (or directly, if needed).
