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 d
ne for the DB.

I think you are going to have to take care of this in your
application code.
At first thought, I would create a class
with synchronized static methods to do each of your
processing tasks. That way, you are guaranteed
only one met
How would you do it in a non-servlet environment?
Exactly the same works here too.
