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 |
---|
30 | installation. When we say, "This information can be found in your |
---|
31 | $CATALINA_HOME/README.txt file" we mean to look at the README.txt file at the |
---|
32 | root of your Tomcat install. Optionally, Tomcat may be configured for multiple |
---|
33 | instances by defining <strong>$CATALINA_BASE</strong> for each instance. If |
---|
34 | multiple instances are not configured, <strong>$CATALINA_BASE</strong> is the |
---|
35 | same as <strong>$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 |
---|
64 | written and easy to understand, we may have missed something. Provided |
---|
65 | below 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 |
---|
68 | issues and solutions vary between the major versions of Tomcat (4.x versus |
---|
69 | 5). As you search around the web, there will be some documentation that |
---|
70 | is not relevant to Tomcat 6, but 3.x, 4.x and 5.x. Doing 3.x or 4.x things to 6 |
---|
71 | will probably not work in most cases as the server.xml files are very |
---|
72 | different.</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> |

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 |
---|
101 | on the TOMCAT-DEV list, or send one of the doc authors email.</p> |
