Custom exporter for scheduled report not registered

[christoph.poelsterl_2]

Hello everyone,

I am running a JasperReports Server v7.5.0 and I implemented a custom exporter following this guide: JasperReports Server Ultimate Guide | Jaspersoft Community
While the Report Viewer part is working like a charm I am having trouble with adding it to the scheduler. I strictly following your naming conventions (I tinhk) except that <MyFormat> is not equal to the resulting file extension. But if I understood correctly this is recommanded but not mandatory.

At the end I want to schedule the report through the reportExecutions REST resource but response tells me: Export format multifilexlsx not supported or misconfigured.
Server log is printing absolutely nothing and deployment is fine.

Hopefully someone can see what mistake I made.

 

Thank you in advance & best regards,

Christoph
