Ok, here is the problem of HTMLUnit. I have this code
url_with_hash_fragment= "http://127.0.0.1:8888/Myproject.html?gwt.codesvr=127.0.0.1:9997#!home";; // use the headless browser to obtain an HTML snapshot final WebClient webClient = new WebClient(); HtmlPage page = webClient.getPage(url_with_hash_fragment); // important! Give the headless browser enough time to execute JavaScript // The exact time to wait may depend on your application. webClient.waitForBackgroundJavaScript(2000); // return the snapshot PrintWriter out = response.getWriter(); out.println(page.asXml()); in my eclipse, it first listed css clode like: gwt-ToggleButton-down { background-position: 0 -513px; border: 1px inset #ccc; cursor: pointer; cursor: hand; } .gwt-ToggleButton-down-hovering { background-position: 0 -513px; border: 1px inset; border-color: #9cf #69e #69e #7af; cursor: pointer; cursor: hand; }.... : null java.util.EmptyStackException at java.util.Stack.peek(Unknown Source) Why we got EmptyStackException problem? If I run http://127.0.0.1:8888/Myproject.html?gwt.codesvr=127.0.0.1:9997#!home without HTMLUnit then everything is fine no issue, but if i run that url under HTMLUnit then I got EmptyStackException How can sure 100% that HtmlUnit will never generate any error for any kind of HTML code?
