    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[])
            PackManager.v().getPack("jtp").add(new Transform ("jtp.annotexample",GetStmts4.v()));
        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();
            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);
            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();
                    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++)

    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.
