Hi,
I have a similar problem as ticketmaster site need to solve. In the ticketMaster web site, when you try to reserved some seats, that seats will locked only for you during your transaction. So that there will be no two persons reserved same seats.
I am working on a JSP/Servlet/Oracle 8.1.7 and Struts 1.1 based web system (note, no EJB). My problem is I need to lock a particular record in Oracle for a period of time, so that only one user on the client side (browser site) can see this particular record.
As soon as one user get the record, all other users will be blocked (not able to read/write onto this record), so at anytime, only one user will working on on record.
Any advise how to do that in a easier way?
Thanks.
David

Can't you do optimistic locking? Just have "first one in wins" in that case and allow simultaneous use.
