Good I am new here but I wanted to ask you for help if someone already had a similar problem.
It turns out that I downloaded a sales system made in Java (Netbeans) that was connected to MySql, this to reports with Japser, everything worked OK. I decided then to change the database to Oracle 11g and manage to make it all work well except the reports.
Every time I want the PDF report to be generated, I get the following console error message:
Error executing SQL statement for: null
The consultations are fine ... I've already tried ... what could it be?
I enclose the url from which I draw the system: link
Additional info: By selecting the preview in the jasper editor, if you pull the correct data from the Oracle.
