How to connect to a Postgresql DB version 15 ?
iReport has not been developed or supported in quite some time. You can download Jaspersoft Studio, it's replacement, from our website and it should allow you to work with older JRXML files. There is a free and paid edition - both will allow for basic report development capabilities. With that said, I believe the basic instructions on connecting iReport to any JDBC capable database haven't changed:
If the driver you need is not listed, you would likely have to install a new driver for Postgres 15...there may be old documentation online about that, but I haven't worked with iReport in many years. I hope this gets you started though.
