Problem during Transaction in update

Question

I am using a Bussiness method UPDATE in which i am first deleting the record and then i am creating  agian the same record with the new values. While performing create operation if any of the values  passed are wrong, then create process fails. and the whole UPDATION fails(also record is lost), to avoid this i wann to rollback the transaction once there arises problem in create process. To perform this kind of rollback what are the transaction properties to be performed.

Answer 1

Transaction mode of an JDBC connection is by default auto-commit. You have to set the transation mode auto-commit  as false.
con.setAutoCommit(false);
//do something
con.commit();
con.setAutoCommit(true);
