Thom,
Thanks -- you're correct that I am using two VM's.
Unfortunately, I'm not in an environment where I
can run the Rmi as a "server"  -- I need to invoke
at as needed and then shut it down.  When I sent
my original question, I was thinking that the
problem may be more of a servlet container
question (when to terminate servlet processing).
But since I can ensure a non-conflict access
schedule, I was hoping that having separate VM's
would not cause a conflict.

| I'm not sure if you guys are dealing with the
same issue.  Steve, I'm
| sorry I didn't get to your question earlier, but
I never got the email
| for some reason.  In your case, it looks like
you have different VMs
| hitting the database, so it is expected that you
won't be able to see
| the data updated from the other VM until you
restart the servlet VM.
| Here is where you could benefit using the
RmiJdbc driver.  Not only is
| this annoying, but you could end up with a
corrupted database.
|
| Alexei, I'm not sure what's happening in your
case, but my first
| question is, are you opening the database from
one JVM only?  It looks
| like this is the case.  If so, the problem may
be that the data from the
| one connection is not getting committed.  Is
your connection pool
| setting autocommit=true when you checkout a
connection?  Are you setting
| autocommit=false in other places?  If you're not
already, try explictly
| committing the data after you insert it.
