I'm trying to get a Solr4 install going, building without slf4j
bindings. I am using branch_4x from svn, and using a homegrown init
script. That script is modeled on what I already have working for
version 3.5.0. Solr and Jetty live in /opt/solr4, and the init script
does a chdir to that directory before firing up jetty. I am pointing
solr.home at /index/solr4, using -Dsolr.solr.home.
/index/solr4/solr.xml exists and has sharedLib="lib".
If I use the standard .war file, sharedLib works as I would expect it
to. The solr.xml file is found and it finds the sharedLib directory
just fine, as you can see from this log excerpt:

The problem that I am having is with the -excl-slf4j.war file, which I
am trying to use in order to use log4j instead of jdk logging. When I
do that, it seems to be unable to find the sharedLib folder in
solr.xml. Because it can't find any slf4j bindings at all, I cannot see
what's going on in the log. Entire log included:

further details.
I also tried putting the slf4j jars in /opt/solr4/lib (jetty's lib
directory). Unsurprisingly, there was no change. Where can I put the
jars to make this work, and how to I tell jetty/solr where to find
them? I would very much like to avoid having to specify individual jars
on the java commandline, because of the upgrade pain that will cause.
Thanks,
Shawn
