java.lang.Object javax.servlet.GenericServlet javax.servlet.http.HttpServlet org.apache.catalina.manager.ManagerServlet
public class ManagerServlet
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:
docBase
attribute
of the context configuration file is used to locate the actual
WAR or directory containing the application.{config-url}
, overriding the
docBase
attribute with the contents of the web
application archive found at {war-url}
./xxx
, based
on the contents of the web application archive found at the
specified URL.path:status:sessions
.
Where path is the context path. Status is either running or stopped.
Sessions is the number of active Sessions.users
resource reference.
/xxx
for this
virtual host./xxx
which were idle for at
least mm minutes./xxx
for this virtual host./xxx
for this virtual host./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.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:
JarURLConnection
class for a
reference to an entire JAR file.JarURLConnection
class for a reference to an entire
JAR file.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.
NOTE - For security reasons, this application will not operate when accessed via the invoker servlet. You must explicitly map this servlet with a servlet mapping, and you will always want to protect it with appropriate security constraints as well.
The following servlet initialization parameters are recognized:
