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
.GWTUpld .gwt-Button:HOVER,
.GWTUpld .DecoratedFileUpload .gwt-Button-over,
.GWTUpld .DecoratedFileUpload .gwt-Anchor-over,
.GWTUpld .DecoratedFileUpload .gwt-Label-over {
color: #af6b29;
}

Is this cos I have /*** ***/ comment line in css & that is why the HtmlUnit
could not parse?
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
