Question

Currently using HtmlUnit.

Getting first login page is no problem, succesfully logging in, getting next page, “clicking” the link to get the “MyDetails” page.

After getting “MyDetails” page, i want to get the same way as im getting the first login form.

Why i need to get the form is that i want to change the password, and the fields are in a form.

When im trying to get the second form, it gives me exception as follows:

com.gargoylesoftware.htmlunit.ElementNotFoundException: elementName=[form] attributeName=[name] attributeValue=[form2]

Gives exception at this line of code:

HtmlForm form2 = page3.getFormByName("form2");

Note: the first form name is “form1” & second form name is “form2”.

Is this a problem with HtmlUnit?

Code:

try {
    WebClient webclient = new WebClient(BrowserVersion.FIREFOX_3_6);
    HtmlPage page1 =   webclient.getPage("http://www.highveld.mobi/pages/clubvip/login.aspx");

    HtmlForm form = page1.getFormByName("form1");
    HtmlSubmitInput buttonLogin = form.getInputByName("cmdLogin");

    HtmlTextInput cellLogin = form.getInputByName("txtCellNumber");
    HtmlPasswordInput passLogin = form.getInputByName("txtLoginPassword");
    cellLogin.setValueAttribute(change);
    passLogin.setValueAttribute(oldPass);

    HtmlPage page2 = buttonLogin.click();

    HtmlAnchor link = page2.getAnchorByHref("updateprofile.aspx");
    HtmlPage page3 = link.click();

    System.out.println(page3.getUrl());
    HtmlForm form2 = page3.getFormByName("form2");


    HtmlPasswordInput pass = form2.getInputByName("txtPassword");
    HtmlPasswordInput passConfirm = form2.getInputByName("txtConfirmPassword");
    HtmlSubmitInput button = form2.getInputByName("cmdUpdate");

    pass.setValueAttribute(newPass);
    passConfirm.setValueAttribute(newPass);

    HtmlPage page4 = button.click();
}

First of all, please update to HtmlUnit 2.9 in case you are using an old version.
Secondly, replace this with this:

System.out.println(page3.getUrl());
HtmlForm form2 = page3.getFormByName("form2");

With this:

System.out.println(page3.getUrl());
System.out.println(page3.asXml());
HtmlForm form2 = page3.getFormByName("form2");

And check for the existance of the form2 element, which I’m pretty sure it shouldn’t be there as it is throwing a ElementNotFoundException.

I usually use XPath instead of getFormByName, you can give it a try too.

Hope this helps!
