 <h2 class="boxed">About this Document</h2>
 <div class="section">
 <p>
 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.
 </p>
 </div>


 <a name="N1001C"></a><a name="About the Demos"></a>
 <h2 class="boxed">About the Demos</h2>
 <div class="section">
 <p>
 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>
 </div>


 <a name="N10025"></a><a name="Indexing Files"></a>
 <h2 class="boxed">Indexing Files</h2>
 <div class="section">
 <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>
 </div>


 <a name="N1003D"></a><a name="Deploying the Demos"></a>
 <h2 class="boxed">Deploying the Demos</h2>
 <div class="section">
 <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>


 <a name="N1004F"></a><a name="Configuration"></a>
 <h2 class="boxed">Configuration</h2>
 <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>
 </div>


 <a name="N10070"></a><a name="Running the Demos"></a>
 <h2 class="boxed">Running the Demos</h2>
 <div class="section">
 <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&gt;&gt;</b>; clicking it takes you to subsequent pages.  </p>
 </div>

	<h2 class="boxed">About this Document</h2>
	<div class="section">
	<p>
	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.
	</p>

	<h2 class="boxed">About the Demos</h2>
	<div class="section">
	<p>
	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.

	<h2 class="boxed">Indexing Files</h2>
	<div class="section">
	<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>

	<div class="section">
	<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>


	<a name="N1004F"></a><a name="Configuration"></a>
	<h2 class="boxed">Configuration</h2>
	<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>
