[Soot-list] Trouble Implementing Interprocedural Analysis

[Armand Navabi]

Eric,

Thanks for the response.  It seems I already have rt.jar in my 
classpath.  See below where I print my classpath environment variable.

anavabi at gator /scratch/anavabi/soot/trunk $ java -Xmx512m 
analysis.globalaccesses.GlobalAccesses analysis.examples.Foo
Analysis for analysis.examples.Foo
first class loaded: analysis.examples.Foo
[Call Graph] For information on where the call graph may be incomplete, 
use the verbose option to the cg phase.
Exception in thread "main" java.lang.RuntimeException:

After your suggestion, I also put the following lines in my code:

    String cp = ".:/scratch/anavabi/soot/soot-2.2.2/classes:" +
      "/scratch/anavabi/soot/jasmin-2.2.2/classes:" +
      "/scratch/anavabi/soot/polyglot-1.3.2/classes:" +
      "/scratch/anavabi/soot/polyglot-1.3.2/cup-classes:" +
      "/opt/sun-jdk-1.4.2.10/jre/lib/rt.jar:" +
      "/opt/sun-jdk-1.4.2.10/jre/lib/jce.jar:" +
      "/opt/sun-jdk-1.4.2.10/jre/lib/jsse.jar";
    Scene.v().setSootClassPath(cp);

    SootClass c = Scene.v().loadClassAndSupport(args[0]);
    ... <same code as before>

I am still getting the can't find Version exception.
