After successful installation it will be prompted to start Apache Tomcat. When the application is started, the notifications panel shows the icon.

To further work with the application, download and copy the following files to the Lib folder of the installed Apache Tomcat:

• jcl-over-slf4j-1.6.6.jar, jul-to-slf4j-1.6.6.jar, slf4j-api-1.6.6.jar, slf4j-log4j12-1.6.6.jar. Files can be taken at: https://repo1.maven.org/maven2/org/slf4j/.

• log4j-1.2.17.jar. The file is available via the URL: http://logging.apache.org/log4j/1.2/download.html.

NOTE. After installing additional files restart Apache Tomcat.

Archive with files for Apache Solr 4.4.0 is available via the URL: https://archive.apache.org/dist/lucene/solr/4.4.0/.

1. Unpack the solr-4.4.0 folder from the archive to the appropriate place, for example, to the root folder of the C drive.

2. In the solr-4.4.0 folder, create two subfolders solr and tomcat-config. In solr-4.4.0\solr create the "app" subfolder.

3. Copy the solr-4.4.0.war file to solr-4.4.0\solr from the solr-4.4.0\dist folder.

4. Create a file with the following contents in the solr-4.4.0\tomcat-config folder:

<?xml version="1.0" encoding="utf-8"?>
<Context docBase="C:\solr-4.4.0\solr\solr-4.4.0.war" crossContext="true">
<Environment name="solr/home" type="java.lang.String" value="C:\solr-4.4.0\solr\app" override="true"/>
</Context>

Specify the path to the solr-4.4.0.war file in the docBase attribute, specify the path to the "app" folder in the "value" attribute.

Further setup is executed in the administration console of Apache Tomcat 7. Open the console by following the URL http://localhost:<port>, where <port> is a port specified at installation.

Click the Manager App button, when the authorization request appears, enter administrator user credentials, which were set at installation of Apache Tomcat. After authorization the window opens containing the list of running applications controlled by Apache Tomcat:

1. In the Context Path (required) box specify the context path, which will be added in the browser field to access Apache Solr parameters, for example, /solr-4.4.0.

2. In the XML Configuration file URL box specify the path to the solr.xml file. Example: C:\solr-4.4.0\tomcat-config\solr.xml.

3. Click the Deploy button.
