processbuilder

I have a UNIX native executable that requires the arguments to be fed in like this prog.exe < foo.txt.

foo.txt has two lines: bar baz

I am using java.lang.ProcessBuilder to execute this command. Unfortunately, prog.exe will only work using the redirect from a file. Is there some way I can mimic this behavior in Java?

Of course, ProcessBuilder pb = new ProcessBuilder("prog.exe", "bar", "baz"); does not work.

Thanks!
