Running Ruby script from Java

I am trying to run a Ruby script from Java by doing the following:

public static void main(String[] args) {
    try {
        Process process = Runtime.getRuntime().exec("ruby /path/to/file/file.rb");
        process.waitFor();
        System.out.println(process.exitValue()); 
    } 
    catch (Exception e) {
        e.printStackTrace();
    }
}

When I this is run, I get 1 as the exit value. In my Ruby script, I am using Watir and Nokogiri thus a browser should be used. Nothing happens.

If I copy ruby /path/to/file/file.rb into my terminal, it runs correctly. Any reason why this isn't working correctly?

You need to consume the standard output and standard error streams to get output from your process and find out what is wrong. See the answer to "Using a thread to capture process output".
