Hi Anders,
It seems like the Tomcat errors were just caused by some lines that
needed commenting out in the default config (and I used plain Tomcat
rather than Jetty because Tomcat7 has newer dependencies than the ones
that will currently work with Jetty on Ubuntu 13.04). I must admit that
it was just my ignorance of postgresql syntax, having only used mysql
before, and I was simply changing the permissions on the wrong database!
The way I proved to myself that Solr wasn't broken on Tomcat was by
breaking it and then having to put it back together again ;-)
I'm meaning to write up what I did for anybody else wanting to use
Ubuntu 13.04 and Tomcat7 with CKAN. I'll let you know if I do.
Best wishes,
Talat
