Question

I need to execute a batch file (in Java 6) and use following code for this:

final String command = "C:\Ruby191\bin\mygem.bat inputfile.dat";
final File parent = new File(aParentDir);
Process proc;
proc = aRuntime.exec(command, null, parent);

But I get this exception:

...Exception: java.io.IOException: Cannot run program "
C:\Ruby191\bin\mygem.bat" (in directory "src\test\resources\...
"): CreateProcess error=267, Directory name invalid

The batch file in question exists in the specified directory.

What is wrong in my code?

Answer 1

Try using double backslashes \\ or single slashes / instead of single backslashes. Check current directory name too.
