<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"/> | |

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 | |
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 | |
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> | |

<p>An exception was encountered trying to start the new web application. | |
Check the Tomcat 6 logs for the details, but likely explanations include | |

<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>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:</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> | |
<div align="left"><table cellspacing="4" cellpadding="0" border="0"><tr><td bgcolor="#023264" width="1" height="1"><img src="./images/void.gif" alt="" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" height="1"><img src="./images/void.gif" alt="" width="1" height="1" vspace="0" hspace="0" border="0"></td><td bgcolor="#023264" width="1" height="1"><img src="./images/void.gif" alt="" width="1" height="1" vspace="0" hspace="0" border="0"></td></tr><tr><td bgcolor="#023264" width="1"><img src="./images/void.gif" alt="" 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. | |
</blockquote></li> | |
</ul> | |

<p><strong>The find leaks diagnostic triggers a full garbage collection. It | |
should be used with extreme caution on production systems.</strong></p> | |
<p>The find leaks diagnostic attempts to identify web applications that have | |
caused memory leaks when they were stopped, reloaded or undeployed. Results | |
should always be confirmed | |
with a profiler. The diagnostic uses additional functionality provided by the | |
StandardHost implementation. It will not work if a custom host is used that | |
does not extend StandardHost.</p> | |
<p>Explicitly triggering a full garbage collection from Java code is documented | |
to be unreliable. Furthermore, depending on the JVM used, there are options to | |
disable explicit GC triggering, like <code>-XX:+DisableExplicitGC</code>. | |
If you want to make sure, that the diagnostics were successfully running a full GC, | |
you will need to check using tools like GC logging, JConsole or similar.</p> | |

<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-script</code> role.</li> | |
</ul> | |
<p>To use custom tasks within Ant, you must declare them first with a | |
<code><taskdef></code> element. Therefore, your <code>build.xml</code> | |
file might look something like this:</p> | |
<table border="1"> | |

<p>Note: The definition of the resources task above will override the resources | |
datatype added in Ant 1.7. If you wish to use the resources datatype you will | |
need to use Ant's namespace support to assign the Tomcat tasks to their own | |
namespace.</p> | |
<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> | |

<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:</p> | |
<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. | |

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* --> | |
type=RequestProcessor</code> which will locate all | |
workers which can process requests and report | |
their state. | |
</li> | |
<li> | |
<code>qry=*%3Aj2eeType=Servlet%2c* --> | |
j2eeType=Servlet</code> which return all loaded servlets. | |
</li> | |
<li> | |
<code>qry=Catalina%3Atype%3DEnvironment%2Cresourcetype%3DGlobal%2Cname%3DsimpleValue --> | |
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. | |

Now that you can query an MBean, its time to muck with Tomcat's internals! | |
The general form of the set command is : | |

So you need to provide 3 request parameters: | |
<ol> | |
<li><code>set</code>: The full bean name</li> | |
<li><code>att</code>: The attribute you wish to alter</li> | |
<li><code>val</code>: The new value </li> | |
</ol> | |
If all goes ok, then it will say OK, otherwise an error message will be | |
shown. For example, lets say we wish to turn up debugging on the fly for the | |
<code>ErrorReportValve</code>. The following will set debugging to 10. | |
