: Maybe my code is out of date, but I didn't see /solr/conf being used : as the path.
yeah .. this was changed starting with the 2006-04-01 nightly builds, Yonik sent out an announcement about it on Mar31. That's when the "solr home" concept was introduced, and the data directory was changed to be relative it. i would suggest you upgrade to a new nightly build, and try using -Dsolr.solr.home : a. Change the CWD - not sure how to do that for a webapp inside of Resin. FYI: there's really no way to do it per webapp, it's just a question of what directory you start resin in -- that's one of the reasons the solr.solr.home system property was created ... but we're realizing now that we can't quite do what we thought we could to support multiple instances in the same server instance, so an additional mechanism is likely to be added soon -- more details can be found on the solr-dev list. (The Solr code base is fairly stable ... but the packaging/configuration of that code is still somewhat in flux, hence the lack of an official release. Prior to it being open sourced, the packaging was very CNET and RPM specific.) -Hoss
