[Soot-list] The Commandline of transform J2EE codes used by soot.

[Bernhard Berger]

Hi,

have you checked your class path? The Java front end tries to resolve a class and fails:

>     100         public Dependencies resolveFromJavaFile(SootClass sootclass) {
>     101                 CompilationUnit u = classNameToCU.get(sootclass.getName());
>     102                 HashSet<SootClass> types = new HashSet<SootClass>();
>     103                 for(TypeDecl typeDecl : u.getTypeDecls()) {
>     104                         collectTypeDecl(typeDecl, types);
>     105                 }

The null pointer exeption in line 103 have to be the dereference of u. Perhaps we should add an additional check.

If you have a compiled version of your project you can also try to analyze the byte code.


Regards,

Bernhard
