Oracle Can't Update

Question

I'm using JSP with an Oracle database now.
When I insert statements using SQLPlus, the data stores successfully. No problems.
But when I shut down SQLPlus, and turn it on again, the data I inserted into the database is gone! The tables still exist, but the inserted data has vanished. When I insert the data again, a simple select statement shows it was inserted successfully. Off and on SQLPlus again and the data is vanished with the empty tables remaining.
Anyone know the problem? Please help if you can.
Yours,

You can either do
execute("set autocommit on");
which will turn on autocommit in Oracle or you can issue a commit command after every transaction:
execute("commit");
You probably want to use the "commit" approach because it allows you to roll back transactions.
You cannot set autocommit through SQL Plus because it is good only for that session -- the SQL Plus one. (OK, you could go in as the Oracle DBA and make a global change to auto commit, but that would probably break a lot other applications.)
