I used Jasper Starter in an implementation I did sometime back for reporting.
The good thing is it is a command line tool not requiring to install the jasper server can someone help me integrating it ?
There is a module that utilises Jasper Reports and you can fiind it here GitHub - saguas/jasper_erpnext_report: Jasper for frappe
Unfortunately, it has not been updated for quite sometime and is quite challenging to install due to its requirement of a java module.
