Re: [eclipselink-users] Long Transactions 
Thanks for the idea Michael.
I was thinking of either building a list of command objects that I haven't committed or list of operations I've already done and then information to be able to rollback the changes. I'm not sure which is better but I'm thinking of the latter where reverting changes would be easier.

I had a similar issue with importing things into the db (i.e only INSERT/UPDATE instructions). I kept manual track of what was inserted, which allowed me to rollback the actions on demand - basically that's the command pattern, where all the commands are persisted to the DB, and each command execution is in a single db transaction.

    Hey everybody,

    We're trying to figure out a good way to use some sort of long
    transaction system.  What we'd like to be able to do is allow
    users to work with a set of entities for 15-30 minutes and then
    let them commit the whole process rather than commit each entity
    separately.  Ideally we'd like to be able to save their work
    part-way through so that it is lost if they lose their connection
    or their system crashes.

    Does anyone have any suggestions on how they would implement
    something like this?
