[Soot-list] This operation requires resolving level BODIES but java.lang.Object is at resolving level SIGNATURES

[Nicholas Irving]

Hi
I am trying to get the example @
http://www.sable.mcgill.ca/listarchives/soot-list/msg01169.html
working but when I run it from the command line I am getting

D:\java\workspaces\soot\CallGraph\bin>java com.darkedges.soot.SootTest
Number of methods in HelloWorld: 2
Set Application classes
Set options to the static main class

I am not sure what I am missing. Any ideas would be gratefully appreciated.
