+<p>For administrators and web developers alike, there are some important bits

+of information you should familiarize yourself with before starting out. This

+terminology behind the Tomcat container. As well, where to go when you need

+<p>In the course of reading these documents, you will run across a number of

+terms; some specific to Tomcat, and others defined by the

+<a href="http://wiki.apache.org/tomcat/Specifications">Servlet and

+JSP specifications</a>.</p>

+

+<ul>

+<li><strong>Context</strong> - In a nutshell, a Context is a

+    web application.</li>

+<li><strong>Term2</strong> - This is it.</li>

+<li><strong>Term3</strong> - This is it!</li>

+

+<p>Throughout the docs, you'll notice there are numerous references to

+<strong>$CATALINA_HOME</strong>. This represents the root of your Tomcat

+installation. When we say, "This information can be found in your

+$CATALINA_HOME/README.txt file" we mean to look at the README.txt file at the

+root of your Tomcat install. Optionally, Tomcat may be configured for multiple

+instances by defining <strong>$CATALINA_BASE</strong> for each instance. If

+multiple instances are not configured, <strong>$CATALINA_BASE</strong> is the

+same as <strong>$CATALINA_HOME</strong>.</p>

+

+<p>These are some of the key tomcat directories:</p>

+

+<ul>

+<li><strong>/bin</strong> - Startup, shutdown, and other scripts. The

+    <code>*.sh</code> files (for Unix systems) are functional duplicates of

+    the <code>*.bat</code> files (for Windows systems).  Since the Win32

+    command-line lacks certain functionality, there are some additional

+    files in here.</li>

+<li><strong>/conf</strong> - Configuration files and related DTDs.  The most

+    important file in here is server.xml.  It is the main configuration file

+    for the container.</li>

+<li><strong>/logs</strong> - Log files are here by default.</li>

+<li><strong>/webapps</strong> - This is where your webapps go.</li>

+</ul>

+

+<p>While we've done our best to ensure that these documents are clearly

+written and easy to understand, we may have missed something.  Provided

+below are various web sites and mailing lists in case you get stuck.</p>

+

+<p>As Tomcat 7 is a new release of Tomcat, keep in mind that some of the

+issues and solutions vary between the major versions of Tomcat (6.x versus

+7.x).  As you search around the web, there will be some documentation that

+is not relevant to Tomcat 7, but 6.x, 5.x or earlier versions.  Doing 3.x

+or 4.x things to 7 will probably not work in most cases as the server.xml

+files are very different.</p>

+

+<ul>

+<li>Current document - most documents will list potential hangups. Be sure

+    to fully read the relevant documentation as it will save you much time

+    and effort. There's nothing like scouring the web only to find out that

+    the answer was right in front of you all along!</li>

+<li><a href="http://wiki.apache.org/tomcat/FAQ">Tomcat FAQ</a></li>

+<li><a href="http://wiki.apache.org/tomcat/">Tomcat WIKI</a></li>

+<li>Tomcat FAQ at <a href="http://www.jguru.com/faq/home.jsp?topic=Tomcat">jGuru</a></li>

+<li>Tomcat mailing list archives - numerous sites archive the Tomcat mailing

+    lists. Since the links change over time, clicking here will search

+    <a href="http://www.google.com/search?q=tomcat+mailing+list+archives">Google</a>.

+    </li>

+<li>The TOMCAT-USER mailing list, which you can subscribe to

+    <a href="http://tomcat.apache.org/lists.html">here</a>. If you don't

+    get a reply, then there's a good chance that your question was probably

+    answered in the list archives or one of the FAQs.  Although questions

+    about web application development in general are sometimes asked and

+    answered, please focus your questions on Tomcat-specific issues.</li>

+<li>The TOMCAT-DEV mailing list, which you can subscribe to

+    <a href="http://tomcat.apache.org/lists.html">here</a>.  This list is

+    <strong>reserved</strong> for discussions about the development of Tomcat

+    itself.  Questions about Tomcat configuration, and the problems you run

+    into while developing and running applications, will normally be more

+    appropriate on the TOMCAT-USER list instead.</li>

+</ul>

+

+<p>And, if you think something should be in the docs, by all means let us know

+on the TOMCAT-DEV list.</p>
