: I've made room, restarted resin, and now solr won't start. No useful messages : in the startup, just a : : [21:01:49.105] Could not start SOLR. Check solr/home property : [21:01:49.105] java.lang.NullPointerException : [21:01:49.105] at org : .apache.solr.servlet.SolrDispatchFilter.init(SolrDispatchFilter.java:100)
that message usually comes after some earlier (possibly much earlier) error about the real cause of the problem (usually with a meaninigful stack trace). I'm guessing that the meaningful error in this case hwoever is something along the lines of "index corrupted" but it might have ust been a stray lock file. -Hoss
