It's not the task scheduler. It's so that the JVM's "current directory" is the one you want it to be.

Alternatively, rather than specifying "start in", you could use a full path to the file, rather than a relative one. You could either hardcode that path (not generally a good idea) or provide it as an argument to the command you set up in Task Scheduler. I would prefer this over the "Start In" option because Java programs generally don't need to know or care what the JVM's current directory is.

I would say it depends on what problem you are deal with. In my case, my *.jar file has a separated configuration file (not in the jar). You probably would want to use “Start in (optional)”. The reason we have a separated configuration file is that non-java programmer people can just edit the file if something changes instead of coming to you and asking you to modify the java code.

I would like to schedule a jar file to run which uses IO.
Can someone help?

Did you specify where your *.jar is?

When we call a .jar file using task scheduler, it runs fine if we don’t use file IO.
However, in my case, I was trying to save a file, I have to specify the ‘Start in (optional)’ in the task scheduler so that the task scheduler knows where to store the file.

The setting is:
Program/script: "C:\Program Files\Java\jre7\bin\javaw.exe"
Arguments: -jar C:\Users\admin\Desktop\TestTask.jar
Start in (optional): C:\Users\admin\Desktop ---- added

Problem solved!

Hi.

I have an executable jar file and am trying to create a scheduled task using windows 7 Task Scheduler.
It runs fine as a .jar file when I double click it. But when I tell task scheduler to run it, it comes up with nothing.

Here is how I create tasks in the scheduler:

Program/script: "C:\Program Files\Java\jre7\bin\javaw.exe"
Arguments: -jar C:\Users\admin\Desktop\TestTask.jar

I have also tried using batch file but it doesn't work either, here is my script in bat file.

start "" "C:\Program Files\Java\jre7\bin\javaw.exe" -jar C:\Users\admin\Desktop\TestTask.jar

It also works fine when I double click the bat file.

How does task scheduler not run .jar files? Or I did something wrong?

My code:

import java.io.BufferedWriter; import java.io.FileWriter; import java.io.IOException; public class Run { public static void main(String[] args) throws IOException { String fileName = "log.txt"; String fileContent = "hello world"; FileWriter fw = new FileWriter(fileName, true); BufferedWriter out = new BufferedWriter(fw); out.write(fileContent+"\n"); out.close(); } }


Can someone please help?
