/**
* Servlet that enables remote management of the web applications installed within the same virtual host as this web
* application is. Normally, this functionality will be protected by a security constraint in the web application
* deployment descriptor. However, this requirement can be relaxed during testing.
*
* This servlet examines the value returned by getPathInfo() and related query parameters to determine what
* action is being requested. The following actions and parameters (starting after the servlet path) are supported:
*
* - /deploy?config={config-url} - Install and start a new web application, based on the contents of the
* context configuration file found at the specified URL. The
docBase attribute of the context
* configuration file is used to locate the actual WAR or directory containing the application.
* - /deploy?config={config-url}&war={war-url}/ - Install and start a new web application, based on the
* contents of the context configuration file found at
{config-url}, overriding the docBase
* attribute with the contents of the web application archive found at {war-url}.
* - /deploy?path=/xxx&war={war-url} - Install and start a new web application attached to context path
*
/xxx, based on the contents of the web application archive found at the specified URL.
* - /list - List the context paths of all currently installed web applications for this virtual host. Each
* context will be listed with the following format
path:status:sessions. Where path is the context path.
* Status is either running or stopped. Sessions is the number of active Sessions.
* - /reload?path=/xxx - Reload the Java classes and resources for the application at the specified path.
* - /resources?type=xxxx - Enumerate the available global JNDI resources, optionally limited to those of the
* specified type (fully qualified Java class name), if available.
* - /serverinfo - Display system OS and JVM properties.
*
- /sessions - Deprecated. Use expire.
*
- /expire?path=/xxx - List session idle time information about the web application attached to context path
*
/xxx for this virtual host.
* - /expire?path=/xxx&idle=mm - Expire sessions for the context path
/xxx which were idle for
* at least mm minutes.
* - /sslConnectorCiphers - Display diagnostic info on SSL/TLS ciphers that are currently configured for each
* connector.
*
- /start?path=/xxx - Start the web application attached to context path
/xxx for this virtual
* host.
* - /stop?path=/xxx - Stop the web application attached to context path
/xxx for this virtual
* host.
* - /threaddump - Write a JVM thread dump.
* - /undeploy?path=/xxx - Shutdown and remove the web application attached to context path
/xxx
* for this virtual host, and remove the underlying WAR file or document base directory. (NOTE - This is only
* allowed if the WAR file or document base is stored in the appBase directory of this host, typically as a
* result of being placed there via the /deploy command.
* - /vminfo - Write some VM info.
* - /save - Save the current server configuration to server.xml
* - /save?path=/xxx - Save the context configuration for the web application deployed with path
*
/xxx to an appropriately named context.xml file in the xmlBase for the associated
* Host.
*
*
* Use path=/ for the ROOT context.
*
*
* The syntax of the URL for a web application archive must conform to one of the following patterns to be successfully
* deployed:
*
*
* - file:/absolute/path/to/a/directory - You can specify 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.
*
*
* NOTE - Attempting to reload or remove the application containing this servlet itself will not succeed.
* Therefore, this servlet should generally be deployed as a separate web application within the virtual host to be
* managed.
*
* The following servlet initialization parameters are recognized:
*
* - debug - The debugging detail level that controls the amount of information that is logged by this servlet.
* Default is zero.
