28<p>Throughout the docs, you'll notice there are numerous references to
29<strong>$CATALINA_HOME</strong>. This represents the root of your Tomcat
30installation. When we say, "This information can be found in your
31$CATALINA_HOME/README.txt file" we mean to look at the README.txt file at the
32root of your Tomcat install. Optionally, Tomcat may be configured for multiple
33instances by defining <strong>$CATALINA_BASE</strong> for each instance. If
34multiple instances are not configured, <strong>$CATALINA_BASE</strong> is the
35same as <strong>$CATALINA_HOME</strong>.</p>
36
37<p>These are some of the key tomcat directories:</p>
38
39<ul>
40<li><strong>/bin</strong> - Startup, shutdown, and other scripts. The
41    <code>*.sh</code> files (for Unix systems) are functional duplicates of
42    the <code>*.bat</code> files (for Windows systems).  Since the Win32
43    command-line lacks certain functionality, there are some additional
44    files in here.</li>
45<li><strong>/conf</strong> - Configuration files and related DTDs.  The most
46    important file in here is server.xml.  It is the main configuration file
47    for the container.</li>
48<li><strong>/logs</strong> - Log files are here by default.</li>
49<li><strong>/webapps</strong> - This is where your webapps go.</li>

63<p>While we've done our best to ensure that these documents are clearly
64written and easy to understand, we may have missed something.  Provided
65below are various web sites and mailing lists in case you get stuck.</p>
66
67<p>As Tomcat 6 is a new release of Tomcat, keep in mind that some of the
68issues and solutions vary between the major versions of Tomcat (4.x versus
695).  As you search around the web, there will be some documentation that
70is not relevant to Tomcat 6, but 3.x, 4.x and 5.x.  Doing 3.x or 4.x things to 6
71will probably not work in most cases as the server.xml files are very
72different.</p>
73
74<ul>
75<li>Current document - most documents will list potential hangups. Be sure
76    to fully read the relevant documentation as it will save you much time
77    and effort. There's nothing like scouring the web only to find out that
78    the answer was right in front of you all along!</li>
79<li><a href="http://tomcat.apache.org/faq/">Tomcat FAQ</a> as maintained by the developers.</li>
80<li><a href="http://wiki.apache.org/tomcat/">Tomcat WIKI</a></li>
81<li>Tomcat FAQ at <a href="http://www.jguru.com/faq/home.jsp?topic=Tomcat">jGuru</a></li>
82<li>Tomcat mailing list archives - numerous sites archive the Tomcat mailing
83    lists. Since the links change over time, clicking here will search
84    <a href="http://www.google.com/search?q=tomcat+mailing+list+archives">Google</a>.
85    </li>
86<li>The TOMCAT-USER mailing list, which you can subscribe to
87    <a href="http://tomcat.apache.org/lists.html">here</a>. If you don't
88    get a reply, then there's a good chance that your question was probably
89    answered in the list archives or one of the FAQs.  Although questions
90    about web application development in general are sometimes asked and
91    answered, please focus your questions on Tomcat-specific issues.</li>
92<li>The TOMCAT-DEV mailing list, which you can subscribe to
93    <a href="http://tomcat.apache.org/lists.html">here</a>.  This list is
94    <strong>reserved</strong> for discussions about the development of Tomcat
95    itself.  Questions about Tomcat configuration, and the problems you run
96    into while developing and running applications, will normally be more
97    appropriate on the TOMCAT-USER list instead.</li>
98</ul>
99
100<p>And, if you think something should be in the docs, by all means let us know
101on the TOMCAT-DEV list, or send one of the doc authors email.</p>
