Determine if Tomcat is running in Windows using the command prompt

Question

Quite simply, how does one determine whether or not Tomcat is running in Windows, using the command prompt?

I am writing a batch script that must do this. This is

Answer 1

If you run Tomcat for Windows not like a service and don't want to exploit JMX the best way is

for /F %%I in ('tasklist /FI "WINDOWTITLE eq Tomcat" /NH') do if %%I==java.exe goto alreadyRun

where:

• Tomcat - the window title of the Tomcat's terminal window by default
• java.exe - the name of the Tomcat's processe. NOT tomcat.exe.

Answer 2

Using WMIC

@echo off
wmic process list brief | find /i "tomcat.exe"
set result=%ERRORLEVEL%
if "%result%"=="1" echo "not running"
if "%result%"=="0" echo "running"

note : /i is to make the find operation case-insensitive.

Answer 3

This is the Windows version of the netstat based UNIX/LINUX solution asked in the question:

@echo off

netstat -na | find "LISTENING" | find /C /I ":8080" > NUL
if %errorlevel%==0 goto :running

echo tomcat is not running
goto :eof

:running
echo tomcat is running

:eof

Answer 4

I check it by calling a vb script from command line

cscript //nologo checkurl.vbs | findstr "200"
IF errorlevel 1 GOTO :not_running 

Save the below script as checkurl.vbs and replace the ip with machines ip

' Create an HTTP object
myURL = "http://10.1.1.1:8080/"
Set objHTTP = CreateObject( "WinHttp.WinHttpRequest.5.1" )

' Download the specified URL
objHTTP.Open "GET", myURL, False
On Error Resume Next
objHTTP.Send
intStatus = objHTTP.Status

If intStatus = 200 Then
    WScript.Echo intStatus
Else
  WScript.Echo "Error Connecting"
End If

I had problems with using sc query command, because even if tomcat crashed, the service would still be shown as running where in actual the port was not accessible

Answer 5

You can try searching for the process and extracting the line

For example:

ps|grep tomcat

Answer 6

Well, I am not very good with scripts but perhaps you could use this as a starting point:

netstat -a -n | findstr :8005

To get if someone is listening in port 8005. That is Tomcat's default port for remote administration, i.e. startup or shutdown.
Alternatively you could use the port that the http server listens to.
Hope this helps
