I'm trying to migrate some jasper reports to Odoo. Apparently, this is something feasible.

However, the reports never run successfully, the system insisting on the following error:

except_orm: (u'2\nNo such file or directory', (<type 'exceptions.OSError'>, OSError(2, 'No such file or directory'), <traceback object at 0x7fd9c56e5950>))

This is how the report is being declared:

<report
            menu="True"
            auto="False"
            id="sale.order3"
            model="sale.order"
            name="sale.order3"
            rml="mymodule/report/mymodule_sale.jrxml"
            string="Sale order (Jasper)"
            usage="default"/>

I've installed the jasper_reports module which is said to be the Odoo-compatible version.

Can anyone point out a working example of a jasper report in Odoo?
