I'm just starting out with java client apps myself, I'm starting to get the bad feeling java client apps have a rather thin user base. Don't understand why, the technology looks great and I'm certain that if I could get it to work as advertised it would be a wonderful tool.

I agree: Java Client looks pretty cool, but is underused.


From what I have managed to grasp so far I think EOGeneralAdaptorException are used only sever-side because they rely on EOAccess

Makes sense.


while clients use EODistribution which leads to the interesting question: how does one trap an optimistic locking failure on the client? I'm still working on that one...

I would guess you catch that IllegalStateException... :-)


I created a fresh new db to run the test so the PK of 1 is ok.

Here is the trace of what happens during execution (sorry about the long post...)

Notice that after the initial fetch, no other SQL is sent to the db so I'm guessing it's complaining about differences in the snapshot cache on the server and the snapshot cache on the client ????

That makes sense to me, but again I'm not much help with Java Client. Given the dearth of responses, I'm guessing there aren't any on the list either :-(

Good luck,

Ok, good.


The app already handles valid optimistic locking exceptions gracefully by warning the user and refaulting.

Here is the exception I get:

I'm not too familiar with the eodistribution framework. I was expecting a EOGeneralAdaptorException.

Is this the first such object in your app? The PK of 1 is a little suspicious.

I'm afraid I'm out of my area of expertise here. Try posting the SQL that gets generated: optimistic locking failures normally only occur if the database has changed, but maybe this problem is something more directly related to JavaClient.
