How do I run a batch file from my Java Application?

by

Batch files are not an executable. They need an application to run them (i.e. cmd).

On UNIX, the script file has shebang (#!) at the start of a file to specify the program that executes it. Double-clicking in Windows is performed by Windows Explorer. CreateProcess does not know anything about that.

Runtime.
   getRuntime().
   exec("cmd /c start \"\" build.bat");

Note: With the start \"\" command, a separate command window will be opened with a blank title and any output from the batch file will be displayed there. It should also work with just `cmd /c build.bat”, in which case the output can be read from the sub-process in Java if desired.
