}

it should work simple click on submit button:

htmlsubmitinput submit = (htmlsubmitinput) form.getfirstbyxpath("//input[@value='submit']"); htmlpage mypage = submit.click(); 

if not can try doing post request programmatically. example here: https://colinhowe.wordpress.com/2009/06/24/htmlunit-how-to-do-a-post/

final webclient webclient = new webclient();  // instead of requesting page directly create webrequestsettings object webrequestsettings requestsettings = new webrequestsettings(   new url("url goes here"), httpmethod.post);  // set request parameters requestsettings.setrequestparameters(new arraylist()); requestsettings.getrequestparameters().add(new namevaluepair("name of value post", "value"));  // finally, can page htmlpage page = webclient.getpage(requestsettings);
