This is a frequently asked question. Please search archives
(archives.java.sun.com) for "long transactions" and "soft locks".
Comprehensive discussions/answers are available.
Basically, don't use regular transactions to solve your problem, but
instead use a soft lock to make sure only one person can use a
particular entity at any time.
