Apparently the UpdateSite NSF method is only supported for Composite apps and XSP apps? I have a new Domino 9 server with the OpenSocial Component loaded, which is supposed to be the most recent supported way to get DOTS working. The only reason I wanted DOTs was to stand up a proof of concept reporting platform using JDBC Access to NSF data aka DomSql.
I tried uploading the dots domsql updateSite to my server's UpdateSites database. It is in place but DOTS does not load the domsql plugins.
When I copied the physical jar files to the osgi-dots plugins folder (which is not clearly described in the DomSql PDF document) , then DOTS did load the domSQL jar files.
This documentation and integration should be worked on, since the UpdateSites NSF based deployment method is a great feature, and continuing to support it consistently wherever possible as a nice way to work with OSGi would help avoid confusion.
