<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>&lt;ResourceLink&gt;</code> elements
nested in a <code>&lt;Context&gt;</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_HOME/conf/[enginename]/[hostname]</code> folder. Here is an
example:
<pre>
&lt;Context path="/manager" debug="0" privileged="true"
docBase="/usr/local/kinetic/tomcat6/server/webapps/manager"&gt;
&lt;/Context&gt;
</pre>
</p>
<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 <code>Manager</code> web application.
<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>

<blockquote><em>
<p>The description below uses the variable name $CATALINA_HOME
to refer to the directory into which you have installed Tomcat 6,
and is the base directory against which most relative paths are
resolved. However, if you have configured Tomcat 6 for multiple
instances by setting a CATALINA_BASE directory, you should use
$CATALINA_BASE instead of $CATALINA_HOME for each of these
references.</p>
</em></blockquote>
<p>It would be quite unsafe to ship Tomcat with default settings that allowed
anyone on the Internet to execute the Manager application on your server.
Therefore, the Manager application is shipped with the requirement that anyone
who attempts to use it must authenticate themselves, using a username and
password that have the role <strong>manager</strong> associated with them.
Further, there is no username in the default users file
(<conf>$CATALINA_HOME/conf/tomcat-users.xml</conf>) that is assigned this
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 the role name
<strong>manager</strong> with it, or add the <strong>manager</strong> role
to some existing username/password combination. Exactly where this is done
depends on which <code>Realm</code> implementation you are using:</p>
<ul>
<li><em>MemoryRealm</em> - If you have not customized your
<code>$CATALINA_HOME/conf/server.xml</code> to select a different one,
Tomcat 6 defaults to an XML-format file stored at
<code>$CATALINA_HOME/conf/tomcat-users.xml</code>, which can be
edited with any text editor. This file contains an XML
<code>&lt;user&gt;</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 the <strong>manager</strong> role 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 <strong>manager</strong> role
to one or more existing users, and/or create one or more new users
with this role 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 <strong>manager</strong>
role to one or more existing users, and/or create one or more new users
with this role 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 role <strong>manager</strong>.</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:
<pre>
&lt;Context path="/manager" privileged="true"
docBase="/usr/local/kinetic/tomcat6/server/webapps/manager"&gt;
&lt;Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.0\.0\.1"/&gt;

<p>where <code>{host}</code> and <code>{port}</code> represent the hostname
and port number on which Tomcat is running, <code>{command}</code>
represents the Manager command you wish to execute, and
<code>{parameters}</code> represents the query parameters
that are specific to that command. In the illustrations below, customize
the host and port appropriately for your installation.</p>
<p>Most commands accept one or more of the following query parameters:</p>
<ul>
<li><strong>path</strong> - The context path (including the leading slash)
of the web application you are dealing with. To select the ROOT web
application, specify "/". <strong>NOTE</strong> -
It is not possible to perform administrative commands on the
Manager application itself.</li>
<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
applciation 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 wil begin with either
<code>OK</code> or <code>FAIL</code>, indicating whether the requested
command was successful or not. In the case of failure, the rest of the first
line will contain a description of the problem that was encountered. Some
commands include additional lines of information as described below.</p>
<p><em>Internationalization Note</em> - The Manager application looks up
its message strings in resource bundles, so it is possible that the strings
have been translated for your platform. The examples below show the English
version of the messages.</p>
<blockquote><em>
<p><strong>WARNING:</strong> the legacy commands <code>/install</code> and
<code>/remove</code> are deprecated.
They are presently equivalent to <code>/deploy</code> and <code>/undeploy</code>,

<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

<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

<h3>Deploy a Directory or War from the Host appBase</h3>
<p>Deploy a web application directory or ".war" file located in your Host
appBase directory. The directory name or the war file name without the ".war"
extension is used as the path.</p>
<p>In this example the web application located in a sub directory named
<code>foo</code> in the Host appBase directory of the Tomcat server is
deployed as the web application context named <code>/foo</code>. Notice
that the context path used is the name of the web application directory.

<h3>Deploy using a Context configuration ".xml" file</h3>
<p>If the Host deployXML flag is set to true you can deploy a web
application using a Context configuration ".xml" file and an optional
".war" file or web application directory. The context <code>path</code>
is not used when deploying a web application using a context ".xml"
configuration file.</p>
<p>A Context configuration ".xml" file can contain valid XML for a
web application Context just as if it were configured in your
Tomcat <code>server.xml</code> configuration file. Here is an
example:
<div align="left"><table cellspacing="4" cellpadding="0" border="0"><tr><td bgcolor="#023264" width="1" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" width="1" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td></tr><tr><td bgcolor="#023264" width="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#ffffff" height="1"><pre>

debug="0"&gt;
&lt;!-- Link to the user database we will get roles from --&gt;
&lt;ResourceLink name="users" global="UserDatabase"
type="org.apache.catalina.UserDatabase"/&gt;
&lt;/Context&gt;
</pre></td><td bgcolor="#023264" width="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td></tr><tr><td bgcolor="#023264" width="1" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" width="1" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td></tr></table></div>
</p>
<p>When the optional <code>war</code> parameter is set to the URL
for a web application ".war" file or directory it overrides any
docBase configured in the context configuration ".xml" file.</p>
<p>Here is an example of deploying an application using a Context
configuration ".xml" file.
<div align="left"><table cellspacing="4" cellpadding="0" border="0"><tr><td bgcolor="#023264" width="1" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" width="1" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td></tr><tr><td bgcolor="#023264" width="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#ffffff" height="1"><pre>

<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>
<div align="left"><table cellspacing="4" cellpadding="0" border="0"><tr><td bgcolor="#023264" width="1" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" width="1" height="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td></tr><tr><td bgcolor="#023264" width="1"><img src="./images/void.gif" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#ffffff" height="1"><pre>

<p>Otherwise, the response will start with <code>FAIL</code> and include an
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.

<p>In addition to the ability to execute Manager commands via HTTP requests,
as documented above, Tomcat 6 includes a convenient set of Task definitions
for the <em>Ant</em> (version 1.4 or later) build tool. In order to use these
commands, you must perform the following setup operations:</p>
<ul>
<li>Download the binary distribution of Ant from
<a href="http://ant.apache.org">http://ant.apache.org</a>.
You must use version <strong>1.4</strong> or later.</li>
<li>Install the Ant distribution in a convenient directory (called
ANT_HOME in the remainder of these instructions).</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>
environment variable.</li>
<li>Configure at least one username/password combination in your Tomcat
user database that includes the <code>manager</code> role.</li>
</ul>
<p>To use custom tasks within Ant, you must declare them first with a
<code>&lt;taskdef&gt;</code> element. Therefore, your <code>build.xml</code>
file might look something like this:</p>
<table border="1">
<tr><td><pre>
&lt;project name="My Application" default="compile" basedir="."&gt;
&lt;!-- Configure the directory into which the web application is built --&gt;
&lt;property name="build" value="${basedir}/build"/&gt;
&lt;!-- Configure the context path for this application --&gt;
&lt;property name="path" value="/myapp"/&gt;
&lt;!-- Configure properties to access the Manager application --&gt;
&lt;property name="url" value="http://localhost:8080/manager"/&gt;
&lt;property name="username" value="myusername"/&gt;
&lt;property name="password" value="mypassword"/&gt;
&lt;!-- Configure the custom Ant tasks for the Manager application --&gt;
&lt;taskdef name="deploy" classname="org.apache.catalina.ant.DeployTask"/&gt;
&lt;taskdef name="list" classname="org.apache.catalina.ant.ListTask"/&gt;
&lt;taskdef name="reload" classname="org.apache.catalina.ant.ReloadTask"/&gt;
&lt;taskdef name="resources" classname="org.apache.catalina.ant.ResourcesTask"/&gt;
&lt;taskdef name="roles" classname="org.apache.catalina.ant.RolesTask"/&gt;
&lt;taskdef name="start" classname="org.apache.catalina.ant.StartTask"/&gt;
&lt;taskdef name="stop" classname="org.apache.catalina.ant.StopTask"/&gt;
&lt;taskdef name="undeploy" classname="org.apache.catalina.ant.UndeployTask"/&gt;
&lt;!-- Executable Targets --&gt;
&lt;target name="compile" description="Compile web application"&gt;
&lt;!-- ... construct web application in ${build} subdirectory, and

&lt;deploy url="${url}" username="${username}" password="${password}"

&lt;/target&gt;
&lt;target name="reload" description="Reload web application"

&lt;reload url="${url}" username="${username}" password="${password}"

<p>Now, you can execute commands like <code>ant deploy</code> to deploy the
application to a running instance of Tomcat, or <code>ant reload</code> to
tell Tomcat to reload it. Note also that most of the interesting values in
this <code>build.xml</code> file are defined as replaceable properties, so
you can override their values from the command line. For example, you might
consider it a security risk to include the real manager password in your
<code>build.xml</code> file's source code. To avoid this, omit the password
property, and specify it from the command line:</p>
<pre>
ant -Dpassword=secret deploy

<p>Using <em>Ant</em> version <strong>1.6.2</strong> or later,
the Catalina tasks offer the option to capture their output in
properties or external files. They support directly the following subset of the
<code>&lt;redirector&gt;</code> type attributes:

<p>A couple of additional attributes can also be specified:

<table border="1" cellpadding="2" cellspacing="0">

This attribute acts only on manager command execution,
any wrong or missing command attribute will still cause Ant execution termination.
</td>
<td align="center" valign="top">No</td>
</tr>
</tbody>
</table>
<p>They also support the embedded <code>&lt;redirector&gt;</code> element
in which you can specify
its full set of attributes, but <code>input</code>, <code>inputstring</code> and
<code>inputencoding</code> that, even if accepted, are not used because they have
no meaning in this context.
Refer to <a href="http://ant.apache.org">ant manual</a> for details on
<code>&lt;redirector&gt;</code> element attributes.
</p>
<p>
Here is a sample build file extract that shows how this output redirection support
can be used:

<p><strong>WARNING:</strong> even if it doesn't make many sense, and is always a bad idea,
calling a Catalina task more than once,
badly set Ant tasks depends chains may cause that a task be called
more than once in the same Ant run, even if not intended to. A bit of caution should be exercised when you are
capturing output from that task, because this could lead to something unexpected:
<ul>
<li>when capturing in a property you will find in it only the output from the <em>first</em> call, because
Ant properties are immutable and once set they cannot be changed,
</li>
<li>when capturing in a file, each run will overwrite it and you will find in it only the <em>last</em> call
output, unless you are using the <code>append="true"</code> attribute, in which case you will
see the output of each task call appended to the file.
</li>
</ul>

get information and set information. For you to really understand the

Where <code>STUFF</code> is the JMX query you wish to perform. For example,
here are some queries you might wish to run:
<ul>
<li>
<code>qry=*%3Atype%3DRequestProcessor%2C* --&gt;
type=RequestProcessor</code> which will locate all
workers which can process requests and report
their state.
</li>
<li>
<code>qry=*%3Aj2eeType=Servlet%2c* --&gt;
j2eeType=Servlet</code> which return all loaded servlets.
</li>
<li>
<code>qry=Catalina%3Atype%3DEnvironment%2Cresourcetype%3DGlobal%2Cname%3DsimpleValue --&gt;
Catalina:type=Environment,resourcetype=Global,name=simpleValue</code>
which look for a specific MBean by the given name.
</li>
</ul>
You'll need to experiment with this to really understand its capabilites.
If you provide no <code>qry</code> parameter, then all of the MBeans will
be displayed. We really recommend looking at the tomcat source code and
understand the JMX spec to get a better understanding of all the queries
you may run.
