Using FreeBSD 10.1 with jetty 8.1 installed using ports and solr 4.10.x.

Install the drupal modules:

cd /usr/local/www/drupal7
drush dl apachesolr apachesolr_autocomplete

Install solr:

cd /usr/ports/textproc/apache-solr
make install clean

Add it to jetty:

cd /usr/local/jetty/webapps
ln -s /usr/local/share/java/classes/solr-4*.war solr.war

Configure jetty:

/etc/rc.conf

jetty_enable=YES
jetty_flags="-DHUDSON_HOME=/usr/local/hudson -Djava.awt.headless=true -Dsolr.solr.home=/usr/local/solr"

/usr/local/jetty/contexts/solr-jetty-context.xml

We have on our drupal site already the apachesolr module installed, so we copy now the configuration file:

mkdir -p /usr/local/solr/drupal
cd !$
cp -R /usr/local/www/drupal7/sites/all/modules/apachesolr/solr-conf/solr-4.x conf

We have to apply to following diff to get it working with solr-4.10:

Create file that solr finds the configuration:

/usr/local/solr/drupal/core.properties

name=drupal

Fix permissions:

cd /usr/local/solr
chown -R www *
chgrp -R www *

Restart jetty:

service jetty restart

Access the site http://hostname:8080/multicore/ to test it. You should see now a dashboard and you can configure the core.

Now access your drupal site and enter the apachesolr configuration. Put in solr server URL: http://localhost:8080/multicore/drupal. If you click on Test connection you should get an ok.

You have now only to index everything and you have solr with drupal up and running.

Secure your jetty installation by make it only available from localhost. To do this edit:

/usr/local/jetty/etc/jetty.xml

    <Call name="addConnector">
      <Arg>
          <New class="org.eclipse.jetty.server.nio.SelectChannelConnector">
            <Set name="host"><Property name="jetty.host" default="localhost"/></Set>
            <Set name="port"><Property name="jetty.port" default="8080"/></Set>

and restart jetty:

service jetty restart
