public class ManagerServlet extends HttpServlet implements ContainerServlet
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
docBaseattribute 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 thedocBaseattribute 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
/xxxfor this virtual host. - /expire?path=/xxx&idle=mm - Expire sessions
for the context path
/xxxwhich 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
/xxxfor this virtual host. - /stop?path=/xxx - Stop the web application attached to
context path
/xxxfor this virtual host. - /threaddump - Write a JVM thread dump.
- /undeploy?path=/xxx - Shutdown and remove the web application
attached to context path
/xxxfor 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 theappBasedirectory of this host, typically as a result of being placed there via the/deploycommand. - /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
/xxxto an appropriately named context.xml file in thexmlBasefor 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.
