I'm getting server output as `7369 Removed`
You're getting that after the code found the record, not after it was deleted, so that doesn't mean much.
I'm not sure what "I'm listing all record from table" does, but the crucial question is - is the record gone from the DB? Have you checked directly via some SQL tool?
The question doesn't have anything to do with
servlets, so I'll move it to a more suitable forum.
