Re: soot createclass tutorial

Yes, that was the problem.  I though it was there, but it wasn't.  Thanks, Chris.

Hi!

Is the runtime library included in the SootClassPath? The easiest way to
do that is to include "rt.jar" in your JRE lib folder.

Cheers,

Hi,

I'm trying to do the first lesson in the second half of the soot 
tutorial.  I can get CreateClassExample.java to compile with 
Sun's SDK 
1.4.1, but I can't get CreateClassExample.class to execute without 
throwing the following exception:

Exception in thread "main" java.lang.RuntimeException: tried to get 
nonexistent field!
        at soot.Scene.getField(Scene.java:329)
        at CreateClassExample.main(CreateClassExample.java:98)

In CreateClassExample:

// add "tmpRef = java.lang.System.out"
units.add(
  Jimple.v().newAssignStmt(
    tmpRef, Jimple.v().newStaticFieldRef(
      Scene.v().getField(
        "<java.lang.System: java.io.PrintStream out>"))));

In Scene.java:
 
public SootField getField(String fieldSignature)
    {
        SootField f = (SootField) 
fieldSignatureToField.get(fieldSignature);
        if (f != null)
            return f;

        throw new RuntimeException("tried to get nonexistent field!");
    }

Also, in the tutorial, r0 and r1 in the sample Jimple output 
need to be 
updated to l0 and tmpRef respectively.

Cheers,
Chris
