Do you have a better suggestion than the record lock then in a web app? 
That's not being sarcastic either, I'm open to suggestions :)

You WANT to put a record lock on a row? And how long do you intend to
hold this lock? The suggestion of "...FOR UPDATE" might work w/in the
servlet or JSP, but once you return to the user there's no guarantee
that the user will be serviced by the same iSeries job next time.

Holding a record lock on a web app is not something you usually want to
do. I guess if you really need to do it, the first thing that comes to
mind is to hold the lock not in the java program, but in a surrogate job
you launch specifically for this task.
