Tomcat service application
Tomcat9 is a service application for running Tomcat 9 as a Windows service.
Tomcat monitor application
Tomcat9w is a GUI application for monitoring and configuring Tomcat services.
The available command line options are:
//ES// | Edit service configuration | This is the default operation. It is called if the no option is provided but the executable is renamed to servicenameW.exe |
//MS// | Monitor service | Put the icon in the system tray |
Command line arguments
Each command line directive is in the form of //XX//ServiceName
The available command line options are:
//TS// | Run the service as console application | This is the default operation. It is called if the no option is provided. The ServiceName is the name of the executable without exe suffix, meaning Tomcat9 |
//RS// | Run the service | Called only from ServiceManager |
//SS// | Stop the service | |
//US// | Update service parameters | |
//IS// | Install service | |
//DS// | Delete service | Stops the service if running |
Command line parameters
Each command line parameter is prefixed with --. If the command line
parameter is prefixed with ++ then it's value will be appended to the
existing option.
If the environment variable with the same name as command line parameter but
prefixed with PR_
exists it will take precedence.
For example:
set PR_CLASSPATH=xx.jar
is equivalent to providing
--Classpath=xx.jar
as command line parameter.

--PidFile | Defines the file name for storing the running process id. Actual file is created in the LogPath directory |
Installing services
The safest way to manually install the service is to use the provided
service.bat script. Administrator privileges are required to run this
script. If necessary, you can use the /user
switch to specify
a user to use for the installation of the service.
NOTE: On Windows Vista or any later operating system with User
Account Control (UAC) enabled you will be asked for additional privileges
when 'Tomcat9.exe' is launched by the script.
If you want to pass additional options to service installer as
PR_*
environment variables, you have to either configure them
globally in OS, or launch the program that sets them with elevated privileges
(e.g. right-click on cmd.exe and select "Run as administrator"; on Windows 8
(or later) or Windows Server 2012 (or later), you can open an elevated command
prompt for the current directory from the Explorer
by clicking on the "File" menu bar). See issue 56143 for details.
Install the service named 'Tomcat9'
C:\> service.bat install
There is a 2nd optional parameter that lets you specify the name of the service, as displayed in Windows services.
Install the service named 'MyService'
C:\> service.bat install MyService
If using tomcat9.exe, you need to use the //IS// parameter.
Install the service named 'Tomcat9'
C:\> tomcat9 //IS//Tomcat9 --DisplayName="Apache Tomcat 9" ^
--Install="C:\Program Files\Tomcat\bin\tomcat9.exe" --Jvm=auto ^
--StartMode=jvm --StopMode=jvm ^
--StartClass=org.apache.catalina.startup.Bootstrap --StartParams=start ^
--StopClass=org.apache.catalina.startup.Bootstrap --StopParams=stop
Updating services
To update the service parameters, you need to use the //US// parameter.
Update the service named 'Tomcat9'
C:\> tomcat9 //US//Tomcat9 --Description="Apache Tomcat Server - http://tomcat.apache.org/ " ^
--Startup=auto --Classpath=%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\bin\bootstrap.jar
If you gave the service an optional name, you need to specify it like this:
Update the service named 'MyService'
C:\> tomcat9 //US//MyService --Description="Apache Tomcat Server - http://tomcat.apache.org/ " ^
--Startup=auto --Classpath=%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\bin\bootstrap.jar
Removing services
To remove the service, you need to use the //DS// parameter.
If the service is running it will be stopped and then deleted.
Remove the service named 'Tomcat9'
C:\> tomcat9 //DS//Tomcat9
If you gave the service an optional name, you need to specify it like this:
Remove the service named 'MyService'
C:\> tomcat9 //DS//MyService
Debugging services
To run the service in console mode, you need to use the //TS// parameter. The service shutdown can be initiated by pressing CTRL+C or CTRL+BREAK. If you rename the tomcat9.exe to testservice.exe then you can just execute the testservice.exe and this command mode will be executed by default.
Run the service named 'Tomcat9' in console mode
C:\> tomcat9 //TS//Tomcat9 [additional arguments]
Or simply execute:
C:\> tomcat9
Multiple Instances
Tomcat supports installation of multiple instances. You can have a single installation of Tomcat with multiple instances running on different IP/port combinations, or multiple Tomcat versions, each running one or more instances on different IP/ports.
Each instance folder will need the following structure:
- conf
- logs
- temp
- webapps
- work
At a minimum, conf should contain a copy of the following files from CATALINA_HOME\conf\. Any files not copied and edited, will be picked up by default from CATALINA_HOME\conf, i.e. CATALINA_BASE\conf files override defaults from CATALINA_HOME\conf.
- server.xml
- web.xml
You must edit CATALINA_BASE\conf\server.xml to specify a unique IP/port for the
instance to listen on. Find the line that contains
<Connector port="8080" ...
and add an address attribute and/or
update the port number so as to specify a unique IP/port combination.
To install an instance, first set the CATALINA_HOME environment variable to the name of the Tomcat installation directory. Then create a second environment variable CATALINA_BASE and point this to the instance folder. Then run "service install" command specifying a service name.
set CATALINA_HOME=c:\tomcat_9
set CATALINA_BASE=c:\tomcat_9\instances\instance1
service install instance1
To modify the service settings, you can run tomcat9w //ES//instance1.
For additional instances, create additional instance folder, update the CATALINA_BASE environment variable, and run the service install again.
set CATALINA_BASE=c:\tomcat_9\instances\instance2
service install instance2
