'How to do HtmlPage refresh using HTMLUNIT Java?

I am facing an issue while refreshing the page. I am using HTMLUNIT.I am using WebClient and HTMLPAge to access a resource.

com.gargoylesoftware.htmlunit.WebClient
com.gargoylesoftware.htmlunit.HtmlPage


WebClient webClient = new WebClient()
webClient.setJavaScriptEnabled(true)
HtmlPage page = (HtmlPage)webClient.getPage(resource)

I need to refresh the page in order to get the new data from the resource. I tried to clear the cache webClient.getCache().clear(); and also tried to access the resource again with

HtmlPage page = (HtmlPage)webClient.getPage(resource)`.

I am getting the same previous data from the resource. I am beginner, can anyone please guide me how to do that.

Thanks, Naga

Did you try this simple one?

page.refresh();

Should do the work.

I had a similar problem some months ago and I did solve it by clearing the cache. Make sure you're using the appropriate variables. Give this code a try (correct any syntactical errors):

public static HtmlPage myGetPage(WebClient webClient, String url,
  boolean clearCache) throws Exception {
    if (clearCache) {
        webClient.getCache().clear();
    }
    return webClient.getPage(url);
}

public void myMethod() {
    WebClient webClient = new WebClient();
    webClient.setJavaScriptEnabled(true);
    String url = "http://stackoverflow.com/users/268273";
    HtmlPage page = myGetPage(webClient, url, false); // We don't clear de cache
    System.out.println(page.asXml()); // Should return original value
    page = myGetPage(webClient, url, true); // We clear the cache
    System.out.println(page.asXml()); // Should return the new value
}

PS: Of course, use your URL :)
