Brett...
My Derby Database is hosted on my HDD in a /db folder under the Java
Application folder...

>" ... if you are using transactions."
The above phrase made me look at my code to see if I am using transactions.
I wrote the derby software some time ago and I have the following lines of
code but I
do not understand why I did the "conn.setAutoCommit(false)" statement...

            //	Control transactions manually...
            //	NOTE:	Auto commit is on by default in JDBC...
            conn.setAutoCommit(false);

Everything is working fine but I wanted to assure myself that the above
operation is OK.

Many Thanks,
Jim...
