[Soot-list] Howto generate a CallGraph?

[Marco Bakera]

Thank you for that hint li xin. Now Soot seems to create the calling graph. 
However I am not able to fetch it from Scene afterwards since soot terminates 
after invocation of soot.Main.main() with a System.exit(). :(

Any suggestions?


I used the following snippet for my tests.

public CallGraphCreator(String clazz) {
		G.reset();

		// setup soot class path
		String cp = System.getProperty("java.class.path");
		String java_home = System.getProperty("java.home");
		Scene.v().setSootClassPath(String.format("%s:%s/lib/rt.jar:%s/lib/jce.jar", 
cp,java_home,java_home));
		
		String opts = "-w " + clazz;
		Main.main(opts.split(" "));
		
		CallGraph callGraph = Scene.v().getCallGraph();
		// The following debug outputs do not appear on console
		LOG.debug("Created call graph");
		LOG.debug(callGraph);
		LOG.debug(new Date());
	}
	
	public static void main(String[] args) {
		new CallGraphCreator(CallGraphCreator.class.getName());
	}
