Run process through java program

Question

I am working in java for Ubuntu environment. I want to execute a script file but through java program. I have tried followings

try{
    Runtime.getRuntime().exec("/usr/lib/flume-ng/bin/flume-ng agent -f /home/c4/Flume/New/ClientAgent.config -n clientAgent");
}
catch(Exception e){
        e.printStackTrace();
    }

And

ProcessBuilder pb = new ProcessBuilder("/usr/lib/flume-ng/bin/flume-ng", "agent", 
               "-f", "/home/c4/Flume/New/ClientAgent.config","-n","clientAgent");
            try{
        pb.start();
    }
    catch(Exception e){
        e.printStackTrace();

    }

But both of these don't start my process named: flume-ng, other are parameters passed to it. Java program compiles successfully but neither gives exception etc nor run process. Please guide me if i am doing something wrong.

Consider Apache Commons Exec

It provides reliable and cross-platform mechanism to launch external processes.

Here is the latest javadoc: http://commons.apache.org/proper/commons-exec/apidocs/index.html

And here is the simple tutorial: http://commons.apache.org/proper/commons-exec/tutorial.html
