Basic runtime error - SQL-status: HY000

I get runtime error
Cant fint path

Cant find Java installation
Cant find source

SQL-status: HY000

Is Java installed? What about the necessary drivers (e.g. libreoffice-sdbc-hsqldb)?

Also: We know nothing about what you did, which version of LO you use, which database you use, which OS you use… We need those infos to be able to help you. A sample file that throws that error would be a very nice and helpful addition.
