I am using cruise control to trigger a batch deploy script and currently the file executes perfectly BUT cruise control does not see the script end. It just keeps spinning (building) and this goes on forever.
My script launches downloads the build extracts it and then starts tomcat with the application deployed. The script also ends with:
exit /B 0
and yet cruise control does not see the script exiting...
Anyone has an idea
To close the loop on this matter, the tags in the cruise control schedule are dumb when it comes to batch files. If the batch file starts application that are in separate windows the build process will not stop until the windows of those programs are stopped. The script I was using was launching tomcat in its own windows as it was a deployment script. Fortunately if you launch the windows from a vbs file instead of a batch the new window is not considered as a child process which is what we want for cruise control to finish its build.

I'm trying to replicate the behavior of Linux where we create an application launcher using Alacarte providing it the command and file name and Icon using batch
However I have never used batch.
The batch file is in the same directory as the java application.
The Batch contains the command as:
java -javaagent:app1.jar -jar app2.jar
Which does the job but It keeps CMD running in the background which during work I always accidentally close it which turns out closing the java app.
How can I can make it so it will disappear after launching the app and keep the app running
On Windows use javaw, as this will not open the console window. See also java vs javaw
I am running my project as jar using java -jar command in Linux machine. As soon as this program run , It produces logs in another directory. Running my program this way requires me to keep the shell open. Now If I have to see the logs , I can't do that in the same shell. I am forced to do that by either doing the duplicate session or new session. Is there any way I can run the jar as background process and see the logs in the same shell ?
If you don't care about it staying alive, something as simple as nohup java -jar myjar.jar & should work. If you need it to be automatically restarted if it crashes or start automatically at boot, you'll want to look into something like systemd or monit.
How can I make java application start with Windows, without needing user interaction in netbeans ??
Follow the below steps:
Create a *.jar file using Netbeans
Create a batch file with the following contents:
javaw.exe -jar path/to/file/your_jar_file.jar
Create a basic task in the Windows Task Scheduler. Select "When I log on" as the trigger. Set the action to starting a program, and choose your batch file as the program.
I am creating a desktop application. I know how to add program to system tray, that consists of a continuous system process, I need instructions on how to add java code to system configuration startup menu. Like antivirus program which automatically executes on starting the system. would be of great help with example code
Write a batch file(.bat) which executes you java program. Add this batch file into the registry in such a way that it will be executed during system startup.
simply write following into your batch file
java filename
In linux you will hv to create a .sh script(executable) that will execute your java program.
put .sh in /etc/rc0.d using following commands
cp name.sh /etc/rc0.d/
chmod +x /etc/rc0.d/name.sh
I have created a small Java application in which there is some code that executes a batch file. The execution of the batch file leads to the command line window to be opened and to display some output messages. I would like to know if there is some way in Java to call this command line window to be closed from within the program...Thanks!
the command window should close automatically when the batch file completes.
and to run a batch file in background/invisibly, check other questions
Start java by using javaw or javaw.exe.
java (java.exe) runs with an associated console window,
javaw (javaw.exe) is the same but without the console window.
see the documentation for the java command.
On Windows also use start to invoke another shell
start javaw ClassName
I'm not sure for Linux&Co. Try using an & after the command to run it in the background
javaw ClassName &
The other way, closing the window from a batch started by Java:
I don't believe that is possible directly from within Java. You can only close the batch file by itself.
Is hard to help without knowing what that batch file is doing. You may try using the start command on windows or the & in Linux to run the process in the background (start has an option to open the window minimized [/MIN] or in the background [/B]).
Or try some hack like using AutoHotKey or some system functionality (some WinAPI-DLL or equivalent in other systems).
As an addition to NimChimpsky's answer:
If you run a batch file in Windows, Windows will automatically open a command window for the batch file, in case the batch file wants to print output or prompt for input. This also applies if you launch the bat file from a Java process.
Unfortunately, Windows itself apparently provides no way to launch a batch file without such a window. To avoid the window, you will have to run the batch file via some helper program. There are several available; google for "run bat no window" to find some.
If you just want the window to go away after the batch file terminates: That should happen automatically. If it does not, some program launched by the batch file is still running.
start /b [bat file name]
