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:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

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.
As an interim measure, I tried putting the jars in a separate directory
and added a commandline option for the classpath. I also downgraded to
1.6.4, because despite asking for a war without it, the war still
contains slf4j-api version 1.6.4. The log still shows that it failed to
find a logger binding - no difference from above.
java -classpath libsolr/log4j-1.2.17.jar:libsolr/slf4j-log4j12-1.6.4.jar
-jar start.jar
In other news, I finally got jetty to pay attention to my
logging.properties file for jdk logging, but I had to do it with a
-Djava.util.logging.config.file=etc/logging.properties option. Trying to
set that property in jetty.xml according to the wiki didn't work. I
notice that the example says 'mortbay' ... perhaps Jetty 8 does it
differently?

I would really prefer to use log4j ... can anyone tell me how I can go
about doing this successfully?
Thanks,
Shawn
