RX7.3 and the PSOFeedImporter-6.7

On a 7.3 instance I’d like to use the PSOFeedImporter (https://github.com/percussion/PSOFeedImporter). I fiddled it to install and can create feed content items, but of course the import fails probably because I haven’t got the content-REST package installed (because it says specifically not to install it on 7.x). I have the 7.3 PSO toolkit installed.

Any advice on how I can get the feed importer up and running on my 7.3?

The server.log error when trying to perform an import is:

2015-05-28 12:26:40,695 WARN [org.apache.cxf.jaxrs.utils.JAXRSUtils] .No operation matching request path /Content/importfeed is found, HTTP Method : GET, ContentType : /, Accept : /,.
2015-05-28 12:26:40,696 WARN [org.apache.cxf.jaxrs.impl.WebApplicationExceptionMapper] WebApplicationException has been caught : no cause is available

Appreciate any input…

Cheers, Andrew
