这是我为HtmlUnit编写的代码

final WebClient webClient = new WebClient();
webClient.getOptions().setJavaScriptEnabled(true);
webClient.getOptions().setCssEnabled(false);
webClient.getOptions().setRedirectEnabled(true);
webClient.getOptions().setThrowExceptionOnScriptError(false);
webClient.setThrowExceptionOnFailingStatusCode(false);
webClient.setTimeout(20000);
//webClient.setSSLClientCertificate(certificateUrl,
       certificatePassword, certificateType);
HtmlPage page1 = (HtmlPage)webClient.getPage("http://oneurl");

但我得到了错误像

WARN APOPERATOR "htmlunit.IncorrectnessListenerImpl" Obsolete content type encountered: 'text/javascript'.
ERROR APOPERATOR "javascript.StrictErrorReporter" runtimeError: message=[The data necessary to complete this operation is not yet available.] sourceName=[http://easypay.swisscom.ch/charging-engine-checkout/js/libs/jquery-1.9.1.min.js] line=[3] lineSource=[null] lineOffset=[0]

有没有人可以帮助在HtmlUnit中启用javascript？
