we have a java application, which is running as windows service. Actually we need to call a batch file to start windows 'calculator' application. But we can't. If we start java application not as a windows service, it is working fine. I have read a post about the same on Calling a batch file from a windows service and done the below configuration.
"first install the service with giving appropriate path to the batch file or exe file then go to run->services.msc->right click on the service ->properties->logon->check enable service to interact with desktop-make it enable "
After that we got a partial success, as it first prompts a permission window as below:
May I suggest that instead of opening a batch file, you just open the calc.exe file instead?
Runtime.getRuntime().exec("c:\\windows\\System32\\calc.exe", null, new File("c:\\windows\\System32\\calc.exe"));
EDIT: If you still want to run it as a batch file, use this:
Runtime.getRuntime().exec("cmd /c start nameOfTheBatchFile.bat");
Please note that the second variable in the exec method is to set up the directory that you want to be calling the program from.

I have created a rest API and executed added the below code in the rest API but when rest API is invoked by the client notepad.exe file is not opened on remote machine.
when we execute the same code using simple java program on remote server its opening the nodepad application. also when this code is invoked using API from client machine, notepad file is opened in background processes but I am not able to see the notepad prompt.
I have to execute some other .exe file in GUI mode, I am facing same issue for that application but I am taking the example of notepad, if I am able to fix this one that will automatically be fixed.
Process process = Runtime.getRuntime().exec(
"cmd /c start notepad.exe",
null,
new File("C:\temp\"));
I have a web application that executes a batch file.
This batch file executes a java class whose output appears in the command window that ran the batch file.
The batch file is written so that any output received from the executed java class is outputted and saved to a text file on the server.
This is performed using the 'Redirecting command output (>)' as discussed here: http://technet.microsoft.com/en-us/library/bb490982.aspx
In Windows Server 2008, this works fine.
We have upgraded our server to Windows Server 2012 and noticed that while the text file is created, the contents are empty.
When we manually click the batch file on the server, the text file has a response written to it. However when we execute the batch file from our web application, the text file is created but has no response text.
Is this a compatibility issue with Windows Server 2012, and if so is there a work around/fix?
For reference we are using a VB.NET web application which calls the batch file by creating an object with CreateObject("WScript.Shell") and then using object.Run(batchfile).
Thank you for any help!
We solved the issue by avoiding batch files altogether.
Instead we call the Java class file directly which fixed our problem.
CMD.exe is the program that implements redirection for command lines. If you want cmd to provide redirection.
cmd /c commandline >> log.file
I find it strange it is created.
I need to write a program which executes
whenever some one logged In to the windows system.
It is for daily report generation purpose.
I have written the program but couldn't get how to execute it on user login.
All the help would really be appreciated.
EDIT most of the people suggesting that I should put file in startup folder, but startup files only execute if 'system started/restarted'... I need to run the program whenever a user login like if the computer is started but locked and then someone unlocks, this program should be executed.
Correct me if I am wrong.
If you are working on a Windows OS then you can create an executable jar file of your java.
In order to make it launch at login you need to include it to the windows startup list.
You can create a batch file (.bat) in which you put:
"<YOUR PATH TO JAVA>/javaw" -jar "YourJar.jar"
Add this .bat file to windows startup check this
Batch/CMD: Adding files to Startup list
Hope it helps !
Setup your java application to run as a windows service.I think this answer will help you.
Answer is here
Create a batch program and put it on startup that should start your target file to run what you want to do.....
batch code :
start java target.java
Must setup the path for startup b4 run....
#happy Dev: hope you already know how to make a .bat in windows, just create a bat file which has line to execute java. or for more help on this you can see:
http://introcs.cs.princeton.edu/java/15inout/windows-cmd.html
Just make sure you have java installed on that machine. and your environment variable is set for java other wise you have to provide the complete java bin path.
Regarding how to run on login. simple way to go:
for windows 7: start menu--> All programs--> find a folder name startup and right click on it. there you can see open for all users open it and place your file there. every time when some user login the bat file will be executed automatically. and remember this wont work on hibernate. or to open that location you can just go to:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup
for Other OS path is almost similar with just a minor difference.
You can use Task Scheduler for Windows Platform and configure which file to call at Login Time.
C:\Windows\system32\taskschd is the location.
Create a basic Task or Create Task...... are the options.!!
You can schedule the time of your task to get executed.
How do I run a Java .jar file as a Windows service on a Windows 2008 server? I have a jar file called SomeJavaFile.jar located under the C:\SomeDirectory directory on a Windows Server 2008 box. I usually just run this jar manually in the command line with: java –cp SomeJavaFile.jar com.ctg.SomeJavaFile and I let it run 24/7.
The problem with our Windows Server is if it restarts I need to run it as a service so it will automatically start as a service upon startup, because our processing for Vistakon runs 24/7. I have Googled around and tried to use a service wrapper and the sc.exe command to create the service.
I put the wrapper service.exe in the C:\SomeDirectory\. I use the following command to create it: sc.exe SomeJavaService binPath= “C:\SomeDirectory\service.exe \”java –jar C:\SomeDirectory\SomeJavaFile.jar\”” type= own start= auto error= ignore. This creates the SomeJavaService service correctly but when I try to start it I get an error that says the service on Local Computer started then stopped.
Some services stop automatically if they are not in use by other services or programs. Do I need to alter my sc.exe command to have the exact previous working command line maybe, by adding in the com.ctg.SomeJavaFile? So should I change This jar should just run in the background and constantly poll/ping the C:/poll directory then if there is data present it processes the data and sends an export file to another directory.
I have used this same .jar file for years successfully and it hasn't changed, but I cannot get it to run as a Windows service. This is the site I use to get the service wrapper http://code.google.com/p/simple-service-wrapper/. Any help would be greatly appreciated!
"winsw" is the standalone version of the Windows Service installer shipping with the Glassfish Java EE reference implementation.
Works well, but is not a fully polished product - I have used it for exactly this purpose for a couple of years. Requires .NET in some recent version on the Windows machine.

I think that the best bet would be wrap your java app with Procrun of Apache Commons Daemon .
Procrun is a set of applications that allow Windows users to wrap
(mostly) Java applications (e.g. Tomcat) as a Windows service.
The service can be set to automatically start when the machine boots
and will continue to run with no user logged onto the machine.
As per my analysis,
The Idle Solution will be writing a VC++ (.net) Windows Service creation program to launch the .bat (that triggers the jar file)/.exe as a System service with all the required call back methods to SCM.
Note : 1. Wrapping the process with sc.exe / srvany.exe would not work as it does not have any call back process to the SCM (Service Control Manager). 2. And java service Wrapper is a third party API (many are LGPL licensed).
If you start your Java code from commandline by using java -j some.jar does it run until you terminate the program, or does it stop by itself?
There needs to be a NON-Deamon Thread, that is running all the time. A JVM will terminate, if there is no thread running, that is not flagged as daemon.
If you have a little budget, buy an installer tool. I use instll4j. With that tool, you can create service launcher and install them during instllation.
The following solution is working fine for me having OpenFire Connection Manager (which is a jar file) running as service on Windows Server.
Download and install the Non-Sucking Service Manager
I didn't use the batch made by OpenFire team, because it didn't work for me (dependencies not found error...) So, make a batch file with the following code :
#ECHO OFF
cd /D "E:\connection_manager\lib"
java -jar startup.jar
and save it as cm_startup.bat in the bin folder of connection manager.
After that you can create the service with NSSM.
So, open a cmd.exe and run the following command :
nssm install ConnManager "E:\connection_manager\lib\cm_startup.bat"
.
Doc & examples
More documentation and examples for the Non-Sucking Service Manager here : https://nssm.cc/usage Actually NSSM as a lot of options available.
Here is a more complexe example :
nssm install solr "%JavaExe%" -Dsolr.solr.home="\"%CD%\solr"\"
-Djetty.home="\"%CD%"\" -Djetty.logs="\"%CD%\logs"\" -cp
"\"%CD%\lib\*.jar"\";"\"%CD%\start.jar"\" -jar "\"%CD%\start.jar"\"
i need to execute a batch file as windows service.
For that i had created a batch file.
In this batch file i just add the below code to run a jar file.
java -jar myTest.jar
When i double click on the batch file..no problem .its working fine. It executes the jar file (a java application).
But the same batch file when i used in a windows service on a windows server, its not working.? Its just getting blinked to show the command window and gets closed. None of my code portion inside the jar file gets executed.
Another thing is i had successfully checked this from another windows server. Its working fine there.
Why this strange issue..??Can anyone help me out to solve the issue..
The service is not executed in the same environment as when you run the batch from an interactive Windows session. Make shure in the .bat file that change into the correct (working) directory, even with absolut path (cd \users\my\java\service), and maybe specify the full path to the java.exe. The other server do you mention could have a totally diferent setup of the environment, installed software, etc.
C:
cd \users\my\java\service
"\program files\java\jre\bin\java" -jar test.jar
