6of information you should familiarize yourself with before starting out. This

8terminology behind the Tomcat container. As well, where to go when you need

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

62<p>While we've done our best to ensure that these documents are clearly
63written and easy to understand, we may have missed something.  Provided
64below are various web sites and mailing lists in case you get stuck.</p>
65
66<p>As Tomcat 6 is a new release of Tomcat, keep in mind that some of the
67issues and solutions vary between the major versions of Tomcat (4.x versus
685).  As you search around the web, there will be some documentation that
69is not relevant to Tomcat 6, but 3.x, 4.x and 5.x.  Doing 3.x or 4.x things to 6
70will probably not work in most cases as the server.xml files are very
71different.</p>
72
73<ul>
74<li>Current document - most documents will list potential hangups. Be sure
75    to fully read the relevant documentation as it will save you much time
76    and effort. There's nothing like scouring the web only to find out that
77    the answer was right in front of you all along!</li>
78<li><a href="http://tomcat.apache.org/faq/">Tomcat FAQ</a> as maintained by the developers.</li>
79<li><a href="http://wiki.apache.org/tomcat/">Tomcat WIKI</a></li>
80<li>Tomcat FAQ at <a href="http://www.jguru.com/faq/home.jsp?topic=Tomcat">jGuru</a></li>
81<li>Tomcat mailing list archives - numerous sites archive the Tomcat mailing
82    lists. Since the links change over time, clicking here will search
83    <a href="http://www.google.com/search?q=tomcat+mailing+list+archives">Google</a>.
84    </li>
85<li>The TOMCAT-USER mailing list, which you can subscribe to
86    <a href="http://tomcat.apache.org/lists.html">here</a>. If you don't
87    get a reply, then there's a good chance that your question was probably
88    answered in the list archives or one of the FAQs.  Although questions
89    about web application development in general are sometimes asked and
90    answered, please focus your questions on Tomcat-specific issues.</li>
91<li>The TOMCAT-DEV mailing list, which you can subscribe to
92    <a href="http://tomcat.apache.org/lists.html">here</a>.  This list is
93    <strong>reserved</strong> for discussions about the development of Tomcat
94    itself.  Questions about Tomcat configuration, and the problems you run
95    into while developing and running applications, will normally be more
96    appropriate on the TOMCAT-USER list instead.</li>
97</ul>
98
99<p>And, if you think something should be in the docs, by all means let us know
100on the TOMCAT-DEV list, or send one of the doc authors email.</p>
