The following page has been changed by DarylBeattie:

The comment on the change is:
Added "JBoss Logging" section and added properties-service to Solr-home.

------------------------------------------------------------------------------
  === Configuring Solr Home ===
  You can configure the Solr home directory globally via ''-Dsolr.solr.home'' in the file ''bin/run.bat''. But that is often not desired because you potentially want more than one Solr installation deployed.
  
- ==== Solr Home via web.xml ====
+ ==== Solr Home Configuration ====
  You can configure the Solr home directory to use per webapp in Solr's ''web.xml'' file. Add following snippet to the web.xml:
  {{{
    <env-entry>
@@ -32, +32 @@

      <env-entry-type>java.lang.String</env-entry-type>
      <env-entry-value>C:\Projects\solr-trunk\example\solr</env-entry-value>
    </env-entry>
+ }}}
+ 
+ You can also configure it (and other Solr variables, such as the Solr-data-dir) in properties-service.xml like so:
+ {{{
+ <mbean code="org.jboss.varia.property.SystemPropertiesService" name="jboss:type=Service,name=SystemProperties">
+   <attribute name="Properties">
+     solr.solr.home=C:/jboss-X/server/default/conf/solr
+     solr.data.dir=C:/solr/data
+   </attribute>
+ </mbean>
+ }}}
+ 
+ ==== JBoss Logging ====
+ By default JBoss uses Log4J for its logging, while the default Solr installation uses the [http://www.slf4j.org/manual.html#binding SLF4J binding] to log via the JDK1.4 logging system. In order to get Solr to log via Log4J, you must replace the slf4j-jdk*.jar binding with the slf4j-log4j*.jar binding. From that point on, logging can be configured via the log4j.xml configuration file.
+ 
+ For example, this can be used to silence all the INFO messages from Solr:
+ {{{
+ <category name="org.apache.solr"> 
+   <priority value="WARN"/>
+ </category>
  }}}
