+
+ <p>The purpose of this specification is to define high level requirements
+ for administrative applications that can be used to manage the operation
+ of a running Tomcat 6 container. A variety of <em>Access Methods</em>
+ to the supported administrative functionality shall be supported, to
+ meet varying requirements:</p>
+ <ul>
+ <li><em>As A Scriptable Web Application</em> - The existing
+ <code>Manager</code> web application provides a simple HTTP-based
+ interface for managing Tomcat through commands that are expressed
+ entirely through a request URI. This is useful in environments
+ where you wish to script administrative commands with tools that
+ can generate HTTP transactions.</li>
+ <li><em>As An HTML-Based Web Application</em> - Use an HTML presentation
+ to provide a GUI-like user interface for humans to interact with the
+ administrative capabilities.</li>
+ <li><em>As SOAP-Based Web Services</em> - The operational commands to
+ administer Tomcat are made available as web services that utilize
+ SOAP message formats.</li>
+ <li><em>As Java Management Extensions (JMX) Commands</em> - The operational
+ commands to administer Tomcat are made available through JMX APIs,
+ for integration into management consoles that utilize them.</li>
+ <li><em>Other Remote Access APIs</em> - Other remote access APIs, such
+ as JINI, RMI, and CORBA can also be utilized to access administrative
+ capabilities.</li>
+ </ul>
+
+ <p>Underlying all of the access methods described above, it is assumed
+ that the actual operations are performed either directly on the
+ corresponding Catalina components (such as calling the
+ <code>Deployer.deploy()</code> method to deploy a new web application),
+ or through a "business logic" layer that can be shared across all of the
+ access methods. This approach minimizes the cost of adding new
+ administrative capabilities later -- it is only necessary to add the
+ corresponding business logic function, and then write adapters to it for
+ all desired access methods.</p>
+
+ <p>The current status of this functional specification is
+ <strong>PROPOSED</strong>. It has not yet been discussed and
+ agreed to on the TOMCAT-DEV mailing list.</p>

+ <li>In a default Tomcat distribution, all administrative capabilities
+ shall be disabled. It shall be necessary for a system
+ administrator to specifically enable the desired access methods
+ (such as by adding a username/password with a specific role to
+ the Tomcat user's database.</li>
+ <li>Administrative functions shall be realized as direct calls to
+ corresponding Catalina APIs, or through a business logic layer
+ that is independent of the access method used to initiate it.</li>
+ <li>The common business logic components shall be implemented in
+ package <code>org.apache.catalina.admin</code>.</li>
+ <li>The common business logic components shall be built as part of the
+ standard Catalina build process, and made visible in the
+ Catalina class loader.</li>
+ <li>The Java components required for each access method shall be
+ implemented in subpackages of <code>org.apache.catalina.admin</code>.
+ </li>
+ <li>The build scripts should treat each access method as optional,
+ so that it will be built only if the corresponding required
+ APIs are present at build time.</li>
+ <li>It shall be possible to save the configured state of the running
+ Tomcat container such that this state can be reproduced when the
+ container is shut down and restarted.</li>
+ <li>Administrative commands to start up and shut down the overall
+ Tomcat container are <strong>out of scope</strong> for the
+ purposes of these applications. It is assumed that other
+ (usually platform-specific) mechanisms will be used for container
+ startup and shutdown.</li>

+ properties are listed <a href="fs-admin-objects.html">here</a>. In general,
+ Administered Objects correspond to components in the Catalina architecture,
+ but these objects are defined separately here for the following reasons:</p>
+ <ul>
+ <li>It is possible that the administrative applications do not expose
+ every possible configurable facet of the underlying components.</li>
+ <li>In some cases, an Administered Object (from the perspective of an
+ administrative operation) is realized by more than one Catalina
+ component, at a finer-grained level of detail.</li>
+ <li>It is necessary to represent the configuration information for a
+ component separately from the component itself (for instance, in
+ order to store that configuration information for later use).</li>
+ <li>It is necessary to represent configuration information (such as
+ a Default Context) when there is no corresponding component instance.
+ </li>
+ <li>Administered Objects, when realized as Java classes, will include
+ methods for administrative operations that have no correspondence
+ to operations performed by the corresponding actual components.</li>
+ </ul>
+
+ <p>It is assumed that the reader is familiar with the overall component
+ architecture of Catalina. For further information, see the corresponding
+ Developer Documentation. To distinguish names that are used as both
+ <em>Administered Objects</em> and <code>Components</code>, different
+ font presentations are utilized. Default values for many properties
