Ok, I have a Filter
public class CrawlServlet implements Filter{ @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpServletRequest httpRequest = (HttpServletRequest) request; String requestQueryString = httpRequest.getQueryString(); if ((requestQueryString != null) && (requestQueryString.contains("_escaped_fragment_"))) { String str="http://127.0.0.1:8888/Myproject.html?gwt.codesvr=127.0.0.1:9997#!article"; // this url work fine, if i open it it will show article. final WebClient webClient = new WebClient(); HtmlPage page = webClient.getPage(str); PrintWriter out = response.getWriter(); out.println(page.asXml()); } } }Ok, now i ran my app in eclipse, & open the url http://127.0.0.1:8888/Myproject.html?gwt.codesvr=127.0.0.1:9997?_escaped_fragment_=article
Then I got this error in eclipse

Can you fix this issue?
Also, How can we make sure HTMLUnit will work OK in all kind of html code?
Note: I am using htmlunit-2.14
