Hmmm, after being stuck on this for hours, I find the answer myself
15minutes after asking for help... as usual. :)
For anyone interested, and no doubt this will not be a revelation for some,
I need the servlet API in my app for it to work, despite being command line.
So adding this to the maven POM fixed everything:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
Perhaps this dependency could be listed on the wiki? Alongside the sample
code for using embedded solr?
http://wiki.apache.org/solr/Solrj
Logback is passing along all of my logging but I suspect I'd have to add
some Solr logging config before it would tell me this itself. I only
stumbled on it by accident:
