I want to use JRAT profiler for my simple java program which is as below:

public class MainController {

    public static int a=4;

    public static void main(String[] args) {


        for(int i=0;i<30;i++)
        {
            methodA();
            //System.out.println("Hello");
        }

    }

        static void methodA()
        {
            System.out.println("This is Method A");
            methodB();
        }

        static void methodB()
        {
            System.out.println("This is Method B");
            methodC();
        }
        static void methodC()
        {
            System.out.println("This is Method C");

        }


}

I run JRAT command as below:
java -javaagent:shiftone-jrat.jar cased/test/MainController

I run following command to see the output:
java -Xmx256M -jar shiftone-jrat.jar

What I see in outputfile is not so good. I was expecting method signature and method call heirarchy in some of the view. Output looks like below:

viewer="org.shiftone.jrat.ui.viewer.SimpleTextOutputViewBuilder"
JRat:INFO (May/11 12:32:57,613) (main) RuntimeContextImpl - logfile created

JRat:INFO (May/11 12:32:57,619) (JRat-Shutdown) FileOutputRegistry - remove PrintWriter[001_JRat-LOG.jrat]

Does anyone know how to get method call and method signature and also method hierarchy(like call graph) ? Also what is instrumentation and injection options do in the viewer ?
I am new to profiling and JRAT. I would really appreciate any help.

Thanks.
