  • Do not use db connections directly in a jsp – Jens Jan 26 '23 at 07:29
  • You can't access `DBname` in the scriptlet as they're executed at different times. The scriptlet is executed on the server, i.e. when the page is constructed, the JavaScript code runs in the browser, i.e. _after_ the page has been delivered. – Thomas Jan 26 '23 at 07:33
