    Default java - soot issue...counting the jimple line numbers??

    Hello everybody,

    I am trying to write a program that takes a java class file...converts it into corresponding jimple code and prints out the jimple statements along with their line numbers. Then I would like to pick out those lines from the jimple code which have a "virtual invoke". The code that I have written looks like below:

    import soot.*;
    import java.util.*;
    import soot.util.*;
    import soot.jimple.Stmt;
    import soot.tagkit.LineNumberTag;
    import soot.baf.*;
    import java.io.*;
     
    public class GetStmts4 extends BodyTransformer implements RetInst
    {
        private static GetStmts4 instance = new GetStmts4();
     
        private GetStmts4() {};
     
        public static GetStmts4 v()
        {
        return instance;
        }
     
        public static void main(String args[])
        {
        soot.options.Options.v().set_keep_line_number(true);
        //soot.options.Options.v().set_whole_program(true);
        //soot.options.Options.v().setPhaseOption("cg","verbose:true");
            PackManager.v().getPack("jtp").add(new Transform ("jtp.annotexample",GetStmts4.v()));
        soot.Main.main(args);
     
        }
     
        protected void internalTransform(Body b, String phaseName, Map options)
        {
        int linenum = 0;
        int count = 0;
        int array[] = new int[20];
        PatchingChain units = b.getUnits();
        Iterator unitsIt = units.iterator();
     
        while(unitsIt.hasNext())
            {
            Unit unit = (Unit)unitsIt.next();
            LineNumberTag tag = (LineNumberTag) unit.getTag("LineNumberTag");
            int index = rt.getIndex();  //to get the index of the jimple line??is this correct??
            System.out.println("Index is :" + index);
           System.out.println(unit);
            if (tag != null)
     
    //wrote the following piece of code but it gives me the line number in the source code...and not the jimple line number
                {
                System.out.println("java line number:"+tag.getLineNumber());
                //System.out.println("tag name:"+tag.getName());
                String string = unit.toString();
                if(string.matches("\\s*.*virtualinvoke.*"))
                    {
                    count++;
                    System.out.println("line number with virtualinvoke:"+tag.getLineNumber());
                    array[count] = tag.getLineNumber();
                    System.out.println("the " +count+ " element in array is : " +array[count]);
                    }
                }
            }
        for(int k = 1;k <= count; k++)
            {
            System.out.println(array[k]);
            }
          }
       }

    I am getting the following error:
    GetStmts4.java:9: GetStmts4 is not abstract and does not override abstract method setIndex(int) in soot.baf.RetInst
    public class GetStmts4 extends BodyTransformer implements RetInst
    ^

    Would be really grateful if somebody could help me out with this.
    Thanks!!!
