hello rhino-experts,

i'm still newbie with rhino and this might be a simple question:

i have a quit long javaScript-code stored in an Java-string and want to execute it. as result i need the html-code thats produced by the js-code.

here is my java-method so far:
******************************
	public void runScript(String s)  {  // throws JavaScriptException
		// Creates and enters a Context. The Context stores information
		// about the execution environment of a script.
		Context cx = Context.enter();
		try {
			// Initialize the standard objects (Object, Function, etc.)
			// This must be done before scripts can be executed. Returns
			// a scope object that we use in later calls.
			Scriptable scope = cx.initStandardObjects();
			// Collect the arguments into a single string.
			//        String s = "";
			//        for (int i=0; i < args.length; i++) {
			//            s += args[i];
			//        }
			// Now evaluate the string we've colected.
			Object result = cx.evaluateString(scope, s, "<cmd>", 1, null);
			// Convert the result to a string and print it.
			System.out.println(Context.toString(result)); //s); //
			
		}catch (Exception e){ // SbErrorReporter serr
			System.out.println("runScript:catch: " + e.toString());
		}
		
		finally {
			// Exit from the context.
			Context.exit();
		}
	}
******************************
first question:
is this the way to execute js? will i get my html with this method?


by now the console return this:
runScript:catch: ReferenceError: "window" is not defined. (<cmd>; line 57)

i need to jump over such errors, because i have no control over the stored js.

second question: 
how can rhino ignore such js-errors?


thanks for helping
