+
+<p>In many production environments, it is very useful to have the capability
+to deploy a new web application, or undeploy an existing one, without having
+to shut down and restart the entire container. In addition, you can request
+an existing application to reload itself, even if you have not declared it
+to be <code>reloadable</code> in the Tomcat 6 server
+configuration file.</p>
+
+<p>To support these capabilities, Tomcat 6 includes a web application
+(installed by default on context path <code>/manager</code>) that supports
+the following functions:</p>
+<ul>
+<li>Deploy a new web application from the uploaded contents of a WAR file.</li>
+<li>Deploy a new web application, on a specified context path, from the
+ server file system.</li>
+<li>List the currently deployed web applications, as well as the
+ sessions that are currently active for those web apps.</li>
+<li>Reload an existing web application, to reflect changes in the
+ contents of <code>/WEB-INF/classes</code> or <code>/WEB-INF/lib</code>.
+ </li>
+<li>List the OS and JVM property values.</li>
+<li>List the available global JNDI resources, for use in deployment
+ tools that are preparing <code><ResourceLink></code> elements
+ nested in a <code><Context></code> deployment description.</li>
+<li>List the available security roles defined in the user database.</li>
+<li>Start a stopped application (thus making it available again).</li>
+<li>Stop an existing application (so that it becomes unavailable), but
+ do not undeploy it.</li>
+<li>Undeploy a deployed web application and delete its document base
+ directory (unless it was deployed from file system).</li>
+</ul>
+
+<p>A default Tomcat installation includes the manager. To add an instance of the
+Manager web application <code>Context</code> to a new host install the
+<code>manager.xml</code> context configuration file in the
+<code>$CATALINA_BASE/conf/[enginename]/[hostname]</code> folder. Here is an
+example:</p>
+<pre>
+<Context
+ docBase="/usr/local/tomcat6/webapps/manager"
+ antiResourceLocking="false" privileged="true" useHttpOnly="true">
+ <Valve className="org.apache.catalina.valves.RemoteAddrValve"
+ allow="127\.0\.0\.1" />
+</Context>
+</pre>
+
+<p>If you have Tomcat configured to support multiple virtual hosts
+(websites) you would need to configure a Manager for each.</p>
+
+<p>There are three ways to use the <strong>Manager</strong> web application.</p>
+<ul>
+<li>As an application with a user interface you use in your browser.
+Here is an example URL where you can replace <code>localhost</code> with
+your website host name: <code>http://localhost/manager/html/</code> .</li>
+<li>A minimal version using HTTP requests only which is suitable for use
+by scripts setup by system administrators. Commands are given as part of the
+request URI, and responses are in the form of simple text that can be easily
+parsed and processed. See <a href="#Supported Manager Commands">
+Supported Manager Commands</a> for more information.</li>
+<li>A convenient set of task definitions for the <em>Ant</em>
+(version 1.4 or later) build tool. See
+<a href="#Executing Manager Commands With Ant">Executing Manager Commands
+With Ant</a> for more information.</li>
+</ul>

+ <p><em>The description below uses the variable name $CATALINA_BASE to refer the
+ base directory against which most relative paths are resolved. If you have
+ not configured Tomcat 6 for multiple instances by setting a CATALINA_BASE
+ directory, then $CATALINA_BASE will be set to the value of $CATALINA_HOME,
+ the directory into which you have installed Tomcat 6.</em></p>
+ </blockquote>
+
+<p>It would be quite unsafe to ship Tomcat with default settings that allowed
+anyone on the Internet to execute the Manager application on your server.
+Therefore, the Manager application is shipped with the requirement that anyone
+who attempts to use it must authenticate themselves, using a username and
+password that have the appropriate role associated with them.
+Further, there is no username in the default users file
+(<code>$CATALINA_BASE/conf/tomcat-users.xml</code>) that is assigned an
+appropriate role. Therefore, access to the Manager application is completely
+disabled by default.</p>
+
+<p>To enable access to the Manager web application, you must either create
+a new username/password combination and associate one of the manager roles with
+it, or add a manager role to some existing username/password combination. There
+are four roles defined by the manager application:</p>
+<ul>
+<li><em>manager-gui</em> - Allows access to the html interface</li>
+<li><em>manager-script</em> - Allows access to the plain text interface</li>
+<li><em>manager-jmx</em> - Allows access to the JMX proxy interface</li>
+<li><em>manager-status</em> - Allows access to the read-only status pages</li>
+</ul>
+<p>The manager application is configured to use the CSRF prevention filter. For
+this filter to be effective, any user assigned the <code>manager-gui</code> role
+must not be assigned the <code>manager-script</code> nor the
+<code>manager-jmx</code> roles.</p>
+
+<p>Exactly where roles are associated to users depends on which
+<code>Realm</code> implementation you are using:</p>
+<ul>
+<li><em>MemoryRealm</em> - If you have not customized your
+ <code>$CATALINA_BASE/conf/server.xml</code> to select a different one,
+ Tomcat 6 defaults to an XML-format file stored at
+ <code>$CATALINA_BASE/conf/tomcat-users.xml</code>, which can be
+ edited with any text editor. This file contains an XML
+ <code><user></code> for each individual user, which might
+ look something like this:

+ which defines the username and password used by this individual to
+ log on, and the role names he or she is associated with. You can
+ add a role, e.g. <strong>manager-gui</strong>, to the comma-delimited
+ <code>roles</code> attribute for one or more existing users, and/or
+ create new users with that assigned role.</li>
+<li><em>JDBCRealm</em> - Your user and role information is stored in
+ a database accessed via JDBC. Add the required role(s) to one or more
+ existing users, and/or create one or more new users with the required
+ role(s) assigned, following the standard procedures for your
+ environment.</li>
+<li><em>JNDIRealm</em> - Your user and role information is stored in
+ a directory server accessed via LDAP. Add the required role(s) to one or
+ more existing users, and/or create one or more new users with the required
+ role(s) assigned, following the standard procedures for your
+ environment.</li>
+</ul>
+
+<p>The first time you attempt to issue one of the Manager commands
+described in the next section, you will be challenged to log on using
+BASIC authentication. The username and password you enter do not matter,
+as long as they identify a valid user in the users database who possesses
+the appropriate role.</p>
+
+<p>In addition to the password restrictions the manager web application
+could be restricted by the remote IP address or host by adding a
+<code>RemoteAddrValve</code> or <code>RemoteHostValve</code>. Here is
+an example of restricting access to the localhost by IP address:</p>
+<pre>
+<Context antiResourceLocking="false" privileged="true" useHttpOnly="true">
+ <Valve className="org.apache.catalina.valves.RemoteAddrValve"
+ allow="127\.0\.0\.1"/>

+

+<li><strong>war</strong> - URL of a web application archive (WAR) file,
+ pathname of a directory which contains the web application, or a
+ Context configuration ".xml" file. You can use URLs in any of the
+ following formats:
+ <ul>
+ <li><strong>file:/absolute/path/to/a/directory</strong> - The absolute
+ path of a directory that contains the unpacked version of a web
+ application. This directory will be attached to the context path
+ you specify without any changes.</li>
+ <li><strong>file:/absolute/path/to/a/webapp.war</strong> - The absolute
+ path of a web application archive (WAR) file. This is valid
+ <strong>only</strong> for the <code>/deploy</code> command, and is
+ the only acceptable format to that command.</li>
+ <li><strong>jar:file:/absolute/path/to/a/warfile.war!/</strong> - The
+ URL to a local web application archive (WAR) file. You can use any
+ syntax that is valid for the <code>JarURLConnection</code> class
+ for reference to an entire JAR file.</li>
+ <li><strong>file:/absolute/path/to/a/context.xml</strong> - The
+ absolute path of a web application Context configuration ".xml"
+ file which contains the Context configuration element.</li>
+ <li><strong>directory</strong> - The directory name for the web
+ application context in the Host's application base directory.</li>
+ <li><strong>webapp.war</strong> - The name of a web application war file
+ located in the Host's application base directory.</li>
+ </ul></li>
+</ul>
+
+<p>Each command will return a response in <code>text/plain</code> format
+(i.e. plain ASCII with no HTML markup), making it easy for both humans and
+programs to read). The first line of the response will begin with either
+<code>OK</code> or <code>FAIL</code>, indicating whether the requested

+<h3>Deploy a Directory or WAR by URL</h3>
+
+<p>Deploy a web application directory or ".war" file located on the Tomcat
+server. If no <code>path</code> is specified, the directory name or the war file
+name without the ".war" extension is used as the path. The <code>war</code>
+parameter specifies a URL (including the <code>file:</code> scheme) for either
+a directory or a web application archive (WAR) file. The supported syntax for
+a URL referring to a WAR file is described on the Javadocs page for the
+<code>java.net.JarURLConnection</code> class. Use only URLs that refer to
+the entire WAR file.</p>
+
+<p>In this example the web application located in the directory
+<code>/path/to/foo</code> on the Tomcat server is deployed as the
+web application context named <code>/footoo</code>.</p>

+<h3>Deployment Notes</h3>
+
+<p>If the Host is configured with unpackWARs=true and you deploy a war
+file, the war will be unpacked into a directory in your Host appBase
+directory.</p>
+
+<p>If the application war or directory is installed in your Host appBase
+directory and either the Host is configured with autoDeploy=true or
+liveDeploy=true, the Context path must match the directory name or
+war file name without the ".war" extension.</p>
+
+<p>For security when untrusted users can manage web applications, the
+Host deployXML flag can be set to false. This prevents untrusted users
+from deploying web applications using a configuration XML file and
+also prevents them from deploying application directories or ".war"
+files located outside of their Host appBase.</p>
+
+
+<h3>Deploy Response</h3>
+
+<p>If installation and startup is successful, you will receive a response
+like this:</p>

+error message. Possible causes for problems include:</p>
+<ul>
+<li><em>Application already exists at path /foo</em>
+ <blockquote>
+ <p>The context paths for all currently running web applications must be
+ unique. Therefore, you must undeploy the existing web
+ application using this context path, or choose a different context path
+ for the new one. The <code>update</code> parameter may be specified as
+ a parameter on the URL, with a value of <code>true</code> to avoid this
+ error. In that case, an undeploy will be performed on an existing
+ application before performing the deployment.</p>
+ </blockquote></li>
+<li><em>Document base does not exist or is not a readable directory</em>
+ <blockquote>
+ <p>The URL specified by the <code>war</code> parameter must identify a
+ directory on this server that contains the "unpacked" version of a
+ web application, or the absolute URL of a web application archive (WAR)
+ file that contains this application. Correct the value specified by
+ the <code>war</code> parameter.</p>
+ </blockquote></li>
+<li><em>Encountered exception</em>
+ <blockquote>
+ <p>An exception was encountered trying to start the new web application.
+ Check the Tomcat 6 logs for the details, but likely explanations include
+ problems parsing your <code>/WEB-INF/web.xml</code> file, or missing
+ classes encountered when initializing application event listeners and
+ filters.</p>
+ </blockquote></li>
+<li><em>Invalid application URL was specified</em>
+ <blockquote>
+ <p>The URL for the directory or web application that you specified
+ was not valid. Such URLs must start with <code>file:</code>, and URLs
+ for a WAR file must end in ".war".</p>
+ </blockquote></li>
+<li><em>Invalid context path was specified</em>
+ <blockquote>
+ <p>The context path must start with a slash character. To reference the
+ ROOT web application use "/".</p>
+ </blockquote></li>
+<li><em>Context path must match the directory or WAR file name:</em>
+ <blockquote>
+ If the application war or directory is installed in your Host appBase
+ directory and either the Host is configured with autoDeploy=true or
+ liveDeploy=true, the Context path must match the directory name or
+ war file name without the ".war" extension.
+ </blockquote></li>
+<li><em>Only web applications in the Host web application directory can
+ be installed</em>
+ <blockquote>
+ If the Host deployXML flag is set to false this error will happen
+ if an attempt is made to deploy a web application directory or
+ ".war" file outside of the Host appBase directory.

+<li>Download the binary distribution of Ant from

+ You must use version <strong>1.4</strong> or later.</li>

+<li>Copy the file <code>server/lib/catalina-ant.jar</code> from your Tomcat 6
+ installation into Ant's library directory (<code>$ANT_HOME/lib</code>).
+ </li>
+<li>Add the <code>$ANT_HOME/bin</code> directory to your <code>PATH</code>
