removed asterisks from "java -version" in a code block, where they are rendered literally

Edited by Steve Rowe:
---------------------------------------------------------------------
This section describes how to install Solr. You can install Solr anywhere that a suitable
Java Runtime Environment (JRE) is available, as detailed below. Currently this includes Linux,
OS X, and Microsoft Windows. The instructions in this section should work for any platform,
with a few exceptions for Windows as noted.

h2. Got Java?

You will need the Java Runtime Environment (JRE) version 1.6 or higher. At a command line,
check your Java version like this:

{code:language=none|borderStyle=solid|borderColor=#666666}
$ java -version
java version "1.6.0_0"
IcedTea6 1.3.1 (6b12-0ubuntu6.1) Runtime Environment (build 1.6.0_0-b12)
OpenJDK Client VM (build 1.6.0_0-b12, mixed mode, sharing)
{code}

The output will vary, but you need to make sure you have version 1.6 or higher. If you don't
have the required version, or if the java command is not found, download and install the latest
version from Sun at [http://java.sun.com/javase/downloads/].

h2. Installing Solr

Solr is available from the Solr website at [http://lucene.apache.org/solr/].

For Linux/Unix/OSX systems, download the {{.gzip}} file. For Microsoft Windows systems, download
the {{.zip}} file.

Solr runs inside a Java servlet container such as Tomcat, Jetty, or Resin. The Solr distribution
includes a working demonstration server in the {{Example}} directory that runs in Jetty. You
can use the example server as a template for your own installation, whether or not you are
using Jetty as your servlet container. For more information about the demonstration server,
see the [Solr Tutorial|https://lucene.apache.org/solr/tutorial.html].

{note}
Solr ships with a working Jetty server, with optimized settings for Solr, inside the {{example}}
directory. It is recommended that you use the provided Jetty server for optimal performance.
If you absolutely must use a different servlet container then continue to the next section
on how to install Solr.
{note}

h3. To install Solr

# Unpack the Solr distribution to your desired location.
\\
\\
# Stop your Java servlet container.
\\
\\
# Copy the {{solr.war}} file from the Solr distribution to the {{webapps}} directory of your
servlet container. Do not change the name of this file: it must be named {{solr.war}}.
\\
\\
# Copy the Solr Home directory {{apache-solr-4.x.0/example/solr/}} from the distribution to
your desired Solr Home location.
\\
\\
# Start your servlet container, passing to it the location of your Solr Home in one of these
ways:
#* Set the Java system property {{solr.solr.home}} to your Solr Home. (for example, using
the example jetty setup: {{java \-Dsolr.solr.home=/some/dir \-jar start.jar}}).
#* Configure the servlet container so that a JNDI lookup of {{java:comp/env/solr/home}} by
the Solr webapp will point to your Solr Home.
#* Start the servlet container in the directory containing {{./solr}}: the default Solr Home
is {{solr}} under the JVM's current working directory ({{$CWD/solr}}).

To confirm your installation, go to the [Solr Admin page|solr:Overview of the Solr Admin UI]&nbsp;at&nbsp;{{[http://localhost:8983/solr/|http://localhost:8983/solr/]}}.
Note that your servlet container may have started on a different port: check the documentation
for your servlet container to troubleshoot that issue. Also note that if that port is already
in use, Solr will not start. In that case, shut down the servlet container running on that
port, or change your Solr port.

For more information about installing and running Solr on different Java servlet containers,
see the [SolrInstall|https://wiki.apache.org/solr/SolrInstall] page on the [Solr Wiki|https://wiki.apache.org/solr/FrontPage].
