[Soot-list] Generating callgraph with a custom entry point

[Zhoulai]

Hi

I guess you should reset your classpath.

You may want to put this line into your java source,

          *  System.out.println( System.getenv("CLASSPATH") ;*

and see whether soot.jimple.toolkits.CallGraph is reachable from the
printed class path ?

You may also want to check your PATH environment, because you used the
"-pp" option.

Hope that helps.

Zell.
