2. Cloned/edited the resin.conf file to include a mapping for
Solr, by adding:

I normally just copy the war to solr.war, so I don't need the mapping...
3. Started up Resin.
It created the <resin root>/webapps/solr-nightly directory, as
expected, but then when I tried to use the Solr servlet it complained
about not finding solrconfig.xml (see stack trace at end of email).
By default, Solr looks in the current-working-directory/solr/conf for
solrconfig.xml and schema.xml,
From the code, it appears to try:
* $CWD/solrconf/
* $CWD/
* $CLASSPATH
Maybe my code is out of date, but I didn't see /solr/conf being used
as the path.
and creates the index under
current-working-directory/solr/data
From the code, I see it being created at $CWD/data, where "data" is
the default if not specified in the solrconfig.xml.
One way you can direct Solr to a different home location is setting
the solr.solr.home property...
./startup -Dsolr.solr.home=/foo/bar/solr
This didn't work for me. I tried a number of different permutations,
but maybe I missed the magic combination. When I grepped the source,
I didn't see this pattern (solr.solr.home) being used anywhere.
I was able to control the location of the config file by using
-Dsolr.configDir=<resin root>/webapps/solr/conf/ to set the location.
But the /data directory still gets created in <resin root>. I saw in
SolrServlet.java's init() method these lines:
String configDir=getServletContext().getInitParameter("solr.configDir");
String dataDir=getServletContext().getInitParameter("solr.dataDir");
Though the servlet doesn't seem to use either, and I didn't see
solr.dataDir being used in the code anywhere, and trying to control
it from the command line didn't seem to work.
I could uncomment & edit the <dataDir> tag in the solrconfig.xml
file, and that worked.
All of the above makes me worried that I'm missing something, or have
the wrong sources, but from what I can tell:
1. The only ways to control the location of the data directory (used
for the index) are...
a. Change the CWD - not sure how to do that for a webapp inside of Resin.
b. Edit the <dataDir> tag in the solrconfig.xml file. This also lets
you change the name of the directory.
2. The only ways to control the location of the config directory are...
a. Change the CWD.
b. Pass -Dsolr.configDir=xxx in the command line to Resin's httpd.sh
script. This also lets you change the name of the directory.
