End javaw.exe process softly with taskkill - java

I encountered a problem closing my javaw.exe process.
I like to do it in a soft way, so taskkill /F won't help.
Trying to close the javaw by taskkill /PID will end up in an "SUCESS" message, but the process still keeps running.
I'm using Windows XP SP 3 and got administrator rights on this machine.
Any ideas?
Thank you very much!

So, finally I found a solution for my problem, but is not solved using taskkill. There is a program written to send a CTRL-BREAK to any process called "SendSignal". I had tried this before, but all my process was responding had been an error-message and it kept running. I changed this program sending CTRL+C. After this I was able to shut my Javaw process gently. Thanks to all, for your help!

You can try:
taskkill /im javaw.exe

How to close java desktop application from .bat file

I have a java stand alone application. I build a jar, and I create a .exe file from this jar file.
Then I can start the application by double click on it. Now I need to create a .bat file to close the exe program. Now I build a .bat file like this:
TASKKILL /F /PID easyManagement.exe
pause
the script is executed without error but the program easyManagement is every time on.
EDIT
In task manager I can display my program like this:
This code:
TASKKILL /IM easyManagement.exe
run without error but the application is on every time.
You are using a wrong parameter for the taskkill command.
The /PID expects a pid and not the name of the program you want to stop.
Use TASKKILL /IM easyManagement.exe
or TASKKILL /F /IM easyManagement.exe to force the program to stop.
The /F might cause problems in the program you want to stop.
The keys Ctrl+C and Ctrl+Z will end the running of a batch file. Check out this link: Is there a way to write Ctrl-C in a batch file?

Socket programing Java ,java.net.BindException: Address already in use: JVM_Bind [duplicate]

In Eclipse, I got this error:
run:
[java] Error creating the server socket.
[java] Oct 04, 2012 5:31:38 PM cascadas.ace.AceFactory bootstrap
[java] SEVERE: Failed to create world : java.net.BindException: Address already in use: JVM_Bind
[java] Java Result: -1
BUILD SUCCESSFUL
Total time: 10 seconds
I'm not sure why it came up now, but it ran fine just a few hours ago. Do I need to restart my machine? How do i get to the bottom of it? I appreciate any tips or advice.
If you know what port the process is running you can type:
lsof -i:<port>.
For instance, lsof -i:8080, to list the process (pid) running on port 8080.
Then kill the process with kill <pid>
Yes you have another process bound to the same port.
TCPView (Windows only) from Windows Sysinternals is my favorite app whenever I have a JVM_BIND error. It shows which processes are listening on which port. It also provides a convenient context menu to either kill the process or close the connection that is getting in the way.
In windows
netstat -ano
will list all the protocols, ports and processes listening .
Use
taskkill -pid "proces to kill" /f
to kill the process listening to the port.
e.g
taskkill -pid 431 /f
In Ubuntu/Unix we can resolve this problem in 2 steps as described below.
Type netstat -plten |grep java
This will give an output similar to:
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 1001 76084 9488/java
Here 8080 is the port number at which the java process is listening and 9488 is its process id (pid).
In order to free the occupied port, we have to kill this process using the kill command.
kill -9 9488
9488 is the process id from earlier. We use -9 to force stop the process.
Your port should now be free and you can restart the server.
In Mac:
Kill process
Terminal: kill <pid>
Find pid:
Terminal: lsof -i:<port>
From Diego Pino answer
(Windows Only)
To kill a process you first need to find the Process Id (pid)
By running the command :
netstat -ano | findstr :yourPortNumber
You will get your Process Id (PID), Now to kill the same process run this command:
taskkill /pid yourid /f
For windows :
Find the process id
netstat -nao | find "8080"
It will show you the process ID as a number.
Example:
TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 18856
Here 18856 is the process ID
Kill that process
taskkill /PID 18856 /F
Output : SUCCESS: The process with PID 18856 has been terminated.
Here using taskkill you are killing the process ID:18856
For linux/Mac:
sudo kill -9 $(sudo lsof -t -i:8080)
Here you find the process by port 8080 using sudo lsof -t -i:8080 and killing it by sudo kill command
You have another process running on the same port.
You could try killing one of the java.exe services running in your task manager - ps make sure you dont kill eclipse since that is listed as java.exe as well. If nothing else works, restarting your machine will fix it anyhow. It looks like youre not shutting down a socket from a previous test. Hope this helps.
For those who are looking for the simplest of the answers (as that is what we usually miss), just stop your running project and start it again.
Most of the time what we do is we forget to stop the project we ran earlier and when we re-run the project it shows such an issue.
I am also attaching a photo to make it clearer (I use 'Spring tool suite').
So what you need to do is either click the button on the extreme right, if you want to relaunch the same project or first click on the button which is 2nd from the right to stop your project and then the button on the extreme left to run your project. I hope this will solve the issue of few of the newer programmers. :)
In Windows CMD line, find out the Process ID that hold a connection on the bind port by entering following command:
C:> netstat -a -o
-a show all connections
-o show process identifier
And then Terminate the process.
You need to close your port
if you are a linux user then type
fuser -k 8080/tcp
This BindException would come when another process is already running in the specified port(8080).
You can use anyone of the following approach.
Change the server port: If you are using Tomcat server and IntelliJ IDE, you can configure the server port by configuring the tomcat server
or
Go to tomcat>conf folder
Edit server.xml
Search "Connector port"
Replace "8080" by your port number
Restart tomcat server.
Kill the existing running process in that port and start the server.
For Linux/Mac
sudo kill -9 $(sudo lsof -t -i:8080)
For Windows
netstat -ano | findstr :8080
taskkill /PID typeyourPIDhere /F
Note: (/F forcefully terminates the process)
Yes, as Guido Simone said it because another process listening to the same port.If you are in Ubuntu You can simply kill that process giving command
sudo kill $(sudo lsof -t -i:[port number])
ex: sudo kill $(sudo lsof -t -i:8080)
But once it didn't work for me.
i gave the command
$ lsof -i:[port]
and it shows nothing.
I checked my docker containers using command
docker ps -a but non of them alive.All containers has stopped
(but i remember ,i stopped one container which was used same port few minutes ago.).To make sure that docker is not the reason,I stop whole docker process using command sudo service docker stop and try again.
Surprisingly eclipse didn't show the error at that time .It run my program perfectly.
Hope my experience will help some one.
The port is already being used by some other process as #Diego Pino said u can use lsof on unix to locate the process and kill the respective one, if you are on windows use netstat -ano to get all the pids of the process and the ports that everyone acquires. search for your intended port and kill.
to be very easy just restart your machine , if thats possible :)
Restart the PC once, I think it will work. It started working in my case. One more thing can be done go to Task Manager and End the process.
In my case Tomcat was running in a background. I've installed it as a external servlet while using Eclipse.
With a Spring Boot in Intellij it has it own server but cannot start while it's already occupied.
In my case Tomcat starts automatically I turn on my OS, that is why I need to shut down him manualy:
$ sudo service tomcat stop
of course "tomcat" depends what version of tomcat you are using.
Hope it might help to someone.
I faced similar issue in Eclipse when two consoles were opened when I started the Server program first and then the Client program. I used to stop the program in the single console thinking that it had closed the server, but it had only closed the client and not the server. I found running Java processes in my Task manager. This problem was solved by closing both Server and Client programs from their individual consoles(Eclipse shows console of latest active program). So when I started the Server program again, the port was again open to be captured.
Your port must be busy in some Other Process. So you can download TCPView on https://technet.microsoft.com/en-us/sysinternals/bb897437 and kill the process for used port.
If you don't know your port, double click on the server that is not starting and click on Open Server Properties Page and click on glassfish from left column. You will find the ports here.
(1) check the port is in use or not, kill that process
$ lsof -i:[port]
(2) another reason is the port is used by ipv6, solution:
edit /etc/sysctl.conf
add this to the file
net.ipv6.conf.all.disable_ipv6 = 1
then make it effect
$ sudo sysctl -p /etc/sysctl.conf
or just reboot
It means some other process is already using the port. In case if this port is being used by some other critical applications and you don't want to close that application, the better way is to choose any other port which is free to use.
Configure your application to use any other port which is free and you will see your application working.
You can close every Java Process and start again your app:
taskkill /F /IM java.exe
start your app again...
I actually just used the Terminate button in Console Tab. It's a small red box. Hope that hepls.

How to save and close the applications using cmd or atleast using java program?

I can kill some applications in cmd using command taskkill /F /IM program_name.exe
But before killing any applications i want to save whatever the work has been done.
EX: kill the Microsoft word, but before that I want to save it. How can I do it through cmd?
Give me an idea. If it is not possible, even through Java also ok for me.
Thanks in advance.
Use this code to terminate the program in Java (in Windows):
try {
Runtime.getRuntime().exec("taskkill /IM word.exe");
} catch (RuntimeException e){
e.printStackTrace();
}
Be note that this can't even save data. Use java.awt.Robot mentioned by Elliott Frisch. (I hadn't use that before)
Taskkill without the /f asks the program to close, like you clicked File - Exit. Most programs will ask if you want to save the current file.
With /f it terminates the program without asking it. Nothing will be saved.
Remove /f from the command.

How To stop an Executed Jar file

It feels like a dumb question to ask, but i cant seem to figure it out. when i run a *.jar file on windows it doesnt apears in the taskmanager processes. how can i terminate it , i have tried TASKKILL but it also doesnt work for me.
On Linux
ps -ef | grep java
It will show u a list of processes out of which one will be your executable jar. Just kill that process by its process id.
sudo kill -9 <pid>
Is there any way to do this from the java code of the same jar file. Like killing itself once process completed.
Find the process id by jps command & and kill them by taskkill command.
Note that "-f" is required with taskkill or it may just send a termination signal not actually terminating it.
You can identify the process in taskmanager by looking for "java" or "javaw" processes. The problem will be in case you are running more than one java processes. If you are able to identify your process, simply kill/end it.
Other way around:
Run
jps -lv
which shows PIDs and command lines of all running Java processes. Determine PID of the task you want to kill. Then use command:
taskkill /PID <pid>
to kill the your jar process.
Did you try to kill the java.exe processes in the taskmanager? It should stop then.
you could open jvisualvm to see the running java-processes. the process-id is displayed there. now open the task-manager go to the processes tab and add the process-id column to be displayed. now you can select the right java.exe or javaw.exe to kill
As everyone stated it is either java or javaw process. The problem is when you're running multiple apps like that. One workaround might be naming the process differently as stated in:
How can I set the process name for a Java-program?
spring boot start/stop sample (on Windows OS).
start.bat
#ECHO OFF
call run.bat start
stop.bat:
#ECHO OFF
call run.bat stop
run.bat
#ECHO OFF
IF "%1"=="start" (
ECHO start your app name
start "yourappname" java -jar -Dspring.profiles.active=prod yourappname-0.0.1.jar
) ELSE IF "%1"=="stop" (
ECHO stop your app name
TASKKILL /FI "WINDOWTITLE eq yourappname"
) ELSE (
ECHO please, use "run.bat start" or "run.bat stop"
)
pause
If you run the JAR file By command line and it is running yet. Press,
In Windows:
• Ctrl+C: shuts down the process, (it might be needed administrator privilege)
In Linux:
• Ctrl+ C : politely ask the process to shut down now.
• Ctrl+ \ : mercilessly kill the process that is currently in the foregroun.
In windows task manager you will see process called "java.exe". Kill that process your application will get stop.
To know the process first go to applications in task manager and then go to process by selecting that application. It will lead you to exact process of that application.

if you are using a jframe and you want your application to stop when you click the "X":
here's a tutorial: http://tips4java.wordpress.com/2009/05/01/closing-an-application/
This is probably the easiest way to kill the process with no external dependencies (jps or anything).

Error running Glassfish 3.1.2.2: Address localhost:4848 is already in use

I have installed my glassfish on port 4848, then I have a test project in IntelliJ IDEA that contains .jsp files which I want to run on glassfish.I've read a tutorial on how to run an application on glassfish via IntelliJ here, but when I do the job I get the following error:
Error running Glassfish 3.1.2.2: Address localhost:4848 is already in use
How to fix this?
From the error you are getting it seems that a glassish instance is already running on that port and IntelliJ is trying to start up a new one. Did you start your glassfish instance via command line? Maybe you could try starting it up with IntelliJ and see if that works better ...
it could be not only glassfish, u could check which application is using port 4848. To do that u should enter "netstat -ao" in your cmd to find that proccess and delete it. Then try again to run glassfish
On S.O. Windows: in console you input netstat -ano and you see the port and service's ID. Then you input taskkill /pid numberIDService or taskkill /f /pid numberIDService
On Linux based OS,
sudo lsof -i:4848
sudo kill <PID>
Open your cmd as administrator
Type Following commands as follows.
netstat -ano | findstr :4848
taskkill /PID 27372 /F
Note: I know the person who put this has already got the answer long time ago. This is for the new comers like me, a clear solution for windows user.
