How can I run a Java from windows batch file but hiding the command window?

I have a .bat file include this command java -jar example.jar that runs example.jar.

I don't want cmd.exe to be visible on screen when the file is being executed. Is this possible?

try {
        String[] command = {"cmd.exe", "/C", "Start /B" , "C:\\path\\urbatname.bat"};
        Process p =  Runtime.getRuntime().exec(command);           
    } catch (Exception ex) {
        ex.printStackTrace();
    }

The /B allow you to execute the batch file invisibly. Just have the codes above in your function and it will work.

Start your bat file using the windows "start" command

Start "" /B "c:\myFolder\MyJavaLauncher.bat"

The "/B" option tell to start the program without showing the typical command window.

you can hide it like this:

start javaw -jar example.jar

Or if you call it from inside of another project you can call like like this:

try {
        Process p = Runtime.getRuntime().exec("cmd /c start /B example.bat");
        p.waitFor();
    } catch (InterruptedException ex) {
        Logger.getLogger(OpenFileFromCmd.class.getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(OpenFileFromCmd.class.getName()).log(Level.SEVERE, null, ex);
    }

If you have any question just ask me :))

Use javaw.exe rather than java.exe this should drop the shell
