Re: Changes in DB Value not Reflected in Output

Without knowing anything else, I am going to guess that the answer is
you misprogrammed some concurrency code--on the desktop, contacting the
database on itself is likely to cause some caches to end up being
flushed and thereby causing memory to become updated across threads,
while a database on the server is not going to cause remote cache flushes.
- why the column in the report file remains as 0 after changing the
value from true to false?
This I can't answer without knowing anything else. Concurrency could
again be a fault here, but I really don't know.
The Java code involves several classes and quite long to post; but I
can provide snippets if it helps.
SSCCE would be invaluable if possible. To beat a horse to a bloody
death, if all other explanations fail, concurrency can be a good guess
for failure, but that does imply that most of the other code is not
buggy in this sense. In any case, I'm not entirely sure what you're
doing or what the correct outputs of those actions should have been, let
alone where in the code it could be failing.
