Issue encountered when installing WAR File Distribution on Debian

Hello,

I'm currently trying to install JasperReports on a Debian server, using the WAR File Distribution.

I followed the steps from the PDF 'jasperreports-server-cp-install-guide', and I encountered an error while using the scripts.

I used the testing script (./js-install-ce.sh test) to pinpoint the issue, here is the result :

I tried searching for the 'SQLState: 08S01' but didn't find anything relevant to my case.

Does someone know how to fix this ?
