Ich verwende HtmlUnit, um einige Informationen von einer Website zu erhalten. Es funktioniert, wenn ich nicht hinter einem Proxy bin. Wenn hinter einem Proxy arbeiten, verwende ich diesen Code, um die Konfiguration einzustellen:HtmlUnit hinter Proxy
WebClient webClient = new WebClient(BrowserVersion.FIREFOX_45);
ProxyConfig proxyConfig = new ProxyConfig();
proxyConfig.setProxyAutoConfigUrl(proxyAutoConfigUrl);
webClient.getOptions().setProxyConfig(proxyConfig);
HtmlPage page = webClient.getPage(config.read().getString("homepage.url"));
FrameWindow fw = page.getFrameByName("mainDataIframe");
...
Aber ich immer eine Fehlermeldung erhalten:

Dieser Fehler tritt niemals ohne Proxy oder in einem Browser. Gibt es jemanden mit einer Idee, warum dieser Fehler passiert? Oder vielleicht jemand, der die Unterschiede bei der Arbeit hinter dem Proxy erkennen kann?
