[Soot-list] Exception in thread "main" java.lang.RuntimeException:, There is no main class set!

[Pauline Anthonysamy]

Hi Quentin,

Thank you so much for your response. I am trying to create the call 
graphs for classes without a main method. From previous posts, I 
understand that it we need to define entry points. If you look at my 
Soot driver class (CallGraphExample) I have defined the entry points.

public class CallGraphExample {
  public static void main(String[] args) {
   // create a list from args
  List<String> argsList = new ArrayList<String>(Arrays.asList(args));
   // add on the following arguments
  argsList.addAll(Arrays.asList(new String[]{"-w", "test.CallGraphs"}));

   // PackManager manages the packs containing the various phases and their
options
  PackManager.v().getPack("wjtp")
  .add(new Transform("wjtp.myTransform", new SceneTransformer() {

@Override
  protected void internalTransform(String phaseName, Map options) {
  CHATransformer.v().transform();
  SootMethod src = Scene.v().getMainClass().getMethodByName("doStuff");
  
  ArrayList<SootMethod> entryPoints = new ArrayList<SootMethod>();
  entryPoints.add(src);
  Scene.v().setEntryPoints(entryPoints);

  CallGraph cg = Scene.v().getCallGraph();
  Iterator<MethodOrMethodContext> targets = new Targets(cg.edgesOutOf(src));

  while (targets.hasNext()) {
  SootMethod tgt = (SootMethod)targets.next();
  System.out.println(src + " may call " + tgt);
  }
  }
  }));
   args = argsList.toArray(new String[0]);
  soot.Main.main(args);
  }
}



Do you have any idea on how I can construct a CFG for classes without 
main method?

Thank you so much for your help!

-Pauline
