When I perform a GET at http://myserver:myport:/jasperserver/rest_v2/organizations I am not surprised that I get a 404 back as the docs indicate this is only in the PRO version. Acording to the help I've received thus far, I should be able to post {"theme":"mytheme"} to http://myserver:myport/jasperserver/rest_v2/organizations/organization_1. This does not work because the resource .../organizations/ is not found. If someone knows what URL to POST|PUT to in order to change the theme from default to jasper_dark for a Jasper 6.2 Community Edition, please post the URL and payload.
