//		JavaScriptEngine sriptEngine = (JavaScriptEngine) webClient.getJavaScriptEngine();
//		HtmlUnitContextFactory factory = sriptEngine.getContextFactory();
//		Context context = factory.enterContext();
//		context.setOptimizationLevel(10);
		System.out.println("ok"+((JavaScriptEngine) webClient.getJavaScriptEngine()).getContextFactory().enterContext().getOptimizationLevel());
		HtmlPage pronote = webClient.getPage("http://92.154.35.11/pronote/eleve.html");
		
		System.out.println("wait");
		while(pronote.getElementById("id_53") == null);
		System.out.println("ok2");
		
		pronote.getElementById("id_53").setAttribute("value", "SecretUsername");
		pronote.getElementById("id_54").setAttribute("value", "*********");
		pronote.getElementById("id_43").click();
		
		System.out.println("wait2");
		while(pronote.getElementById("id_86id_4") == null); // Got the error here
		
		System.out.println(pronote.getDocumentElement().asText());
		
		webClient.close();
