This document is intended as a "getting started" guide to installing and running the Lucene
|
|
|
|
|
web application demo. This guide assumes that you have read the information in the previous two
|
|
|
|
|
examples. We'll use Tomcat as our reference web container. These demos should work with nearly any
|
|
|
|
|
container, but you may have to adapt them appropriately.

The Lucene Web Application demo is a template web application intended for deployment on Tomcat or a
|
|
|
|
|
similar web container. It's NOT designed as a "best practices" implementation by ANY means. It's
|
|
|
|
|
more of a "hello world" type Lucene Web App. The purpose of this application is to demonstrate
|
|
|
|
|
Lucene. With that being said, it should be relatively simple to create a small searchable website
|
|
|
|
|
in Tomcat or a similar application server.

<p> Once you've gotten this far you're probably itching to go. Let's start by creating the index
|
|
|
|
|
you'll need for the web examples. Since you've already set your CLASSPATH in the previous examples,
|
|
|
|
|
all you need to do is type:
|
|
|
|
|
|
|
|
|
|
<pre>
|
|
|
|
|
java org.apache.lucene.demo.IndexHTML -create -index {index-dir} ..
|
|
|
|
|
</pre>
|
|
|
|
|
|
|
|
|
|
You'll need to do this from a (any) subdirectory of your <span class="codefrag">{tomcat}/webapps</span> directory
|
|
|
|
|
(make sure you didn't leave off the <span class="codefrag">..</span> or you'll get a null pointer exception).
|
|
|
|
|
<span class="codefrag">{index-dir}</span> should be a directory that Tomcat has permission to read and write, but is
|
|
|
|
|
outside of a web accessible context. By default the webapp is configured to look in
|
|
|
|
|
<span class="codefrag">/opt/lucene/index</span> for this index.
|
|
|

|
<p>Located in your distribution directory you should see a war file called
|
|
|
|
|
<span class="codefrag">luceneweb.war</span>. If you're working with a Subversion checkout, this will be under the
|
|
|
|
|
<span class="codefrag">build</span> subdirectory. Copy this to your <span class="codefrag">{tomcat-home}/webapps</span> directory.
|
|
|
|
|
You may need to restart Tomcat. </p>

<div class="section">
|
|
|
|
|
<p> From your Tomcat directory look in the <span class="codefrag">webapps/luceneweb</span> subdirectory. If it's not
|
|
|
|
|
present, try browsing to <span class="codefrag">http://localhost:8080/luceneweb</span> (which causes Tomcat to deploy
|
|
|
|
|
the webapp), then look again. Edit a file called <span class="codefrag">configuration.jsp</span>. Ensure that the
|
|
|
|
|
<span class="codefrag">indexLocation</span> is equal to the location you used for your index. You may also customize
|
|
|
|
|
the <span class="codefrag">appTitle</span> and <span class="codefrag">appFooter</span> strings as you see fit. Once you have finished
|
|
|
|
|
altering the configuration you may need to restart Tomcat. You may also wish to update the war file
|
|
|
|
|
by typing <span class="codefrag">jar -uf luceneweb.war configuration.jsp</span> from the <span class="codefrag">luceneweb</span>
|
|
|
|
|
subdirectory. (The -u option is not available in all versions of jar. In this case recreate the
|
|
|
|
|
war file).

<p>Now you're ready to roll. In your browser set the url to
|
|
|
|
|
<span class="codefrag">http://localhost:8080/luceneweb</span> enter <span class="codefrag">test</span> and the number of items per
|
|
|
|
|
page and press search.</p>
|
|
|
|
|
<p>You should now be looking either at a number of results (provided you didn't erase the Tomcat
|
|
|
|
|
examples) or nothing. If you get an error regarding opening the index, then you probably set the
|
|
|
|
|
path in <span class="codefrag">configuration.jsp</span> incorrectly or Tomcat doesn't have permissions to the index
|
|
|
|
|
(or you skipped the step of creating it). Try other search terms. Depending on the number of items
|
|
|
|
|
per page you set and results returned, there may be a link at the bottom that says <b>More
|
|

Results>></b>; clicking it takes you to subsequent pages. </p>
