|
| 8 | <p>This manual contains reference information about all of the configuration
|
| 9 | directives that can be included in a <code>conf/server.xml</code> file to
|
| 10 | configure the behavior of the Tomcat 6 Servlet/JSP container. It does not
|
| 11 | attempt to describe which configuration directives should be used to perform
|
| 12 | specific tasks - for that, see the various <em>HOW-TO</em> documents on the
|
| 13 | main index page.</p>
|
| 14 |
|
| 15 | <p>Tomcat configuration files are formatted as schemaless XML; elements and
|
| 16 | attributes are case-sensitive. Apache Ant-style variable substitution
|
| 17 | is supported; a system property with the name <code>propname</code> may be
|
| 18 | used in a configuration file using the syntax <code>${propname}</code>. All
|
| 19 | system properties are available including those set using the <code>-D</code>
|
| 20 | syntax, those automatically made available by the JVM and those configured in
|
| 21 | the <code>$CATALINA_BASE/conf/catalina.properties</code> file.
|
| 22 | </p>
|
| 23 |
|
| 24 | <p>The configuration element descriptions are organized into the following
|
| 25 | major categories:</p>
|
| 26 | <ul>
|
| 27 | <li><strong>Top Level Elements</strong> - <code><Server></code> is the
|
| 28 | root element of the entire configuration file, while
|
| 29 | <code><Service></code> represents a group of Connectors that is
|
| 30 | associated with an Engine.</li>
|
| 31 | <li><strong>Connectors</strong> - Represent the interface between external
|
| 32 | clients sending requests to (and receiving responses from) a particular
|
| 33 | Service.</li>
|
| 34 | <li><strong>Containers</strong> - Represent components whose function is to
|
| 35 | process incoming requests, and create the corresponding responses.
|
| 36 | An Engine handles all requests for a Service, a Host handles all requests
|
| 37 | for a particular virtual host, and a Context handles all requests for a
|
| 38 | specific web application.</li>
|
| 39 | <li><strong>Nested Components</strong> - Represent elements that can be
|
| 40 | nested inside the element for a Container. Some elements can be nested
|
| 41 | inside any Container, while others can only be nested inside a
|
| 42 | Context.</li>
|
| 43 | </ul>
|
| 44 |
|
| 45 | <p>For each element, the corresponding documentation follows this general
|
| 46 | outline:</p>
|
| 47 | <ul>
|
| 48 | <li><strong>Introduction</strong> - Overall description of this particular
|
| 49 | component. There will be a corresponding Java <em>interface</em> (in
|
| 50 | the <code>org.apache.catalina</code> package) that is implemented by one
|
| 51 | or more standard implementations.</li>
|
| 52 | <li><strong>Attributes</strong> - The set of attributes that are legal for
|
| 53 | this element. Generally, this will be subdivided into <em>Common</em>
|
| 54 | attributes that are supported by all implementations of the corresponding
|
| 55 | Java interface, and <em>Standard Implementation</em> attributes that are
|
| 56 | specific to a particular Java class that implements this interface.
|
| 57 | The names of required attributes are <strong>bolded</strong>.</li>
|
| 58 | <li><strong>Nested Components</strong> - Enumerates which of the <em>Nested
|
| 59 | Components</em> can be legally nested within this element.</li>
|
| 60 | <li><strong>Special Features</strong> - Describes the configuration of a large
|
| 61 | variety of special features (specific to each element type) that are
|
| 62 | supported by the standard implementation of this interface.</li>
|
| 63 | </ul>
