[SOLVED] Problem with ProcessBuilder in java

Hi All,

I am trying to invoke a command line script from java using ProcessBuilder. Here is how my code looks like.

ProcessBuilder pb = new ProcessBuilder(commandToRun.trim());
pb.directory(new File(fromproddir));
p = pb.start();

But it is not executing the command and fails with the exception"CreateProcess error=123, The filename, directory name, or volume label syntax is incorrect". However, this same command runs perfectly from commandline. It also works from Runtime.exec as given below.

p=Runtime.getRuntime().exec(commandToRun, null,new File(fromproddir));

Any one has any idea when processbuilder throws this error.

PS: commandToRun invokes 7za script to zip a directory.

Thanks,
Lakshmi

You have to pass the arguments as separate elements in an array/list:

Code:

String directory = getDirectory();
String[] commandToRun = { "7za", "-option", "-option2", directory };
ProcessBuilder pb = new ProcessBuilder(commandToRun);
