Re: [Htmlunit-user] java.lang.ClassCastException: com.gargoylesoftware.htmlunit.TextPage cannot be cast to com.gargoylesoftware.htmlunit.html.HtmlPage

Hi

As Sreenadh mentioned not every response is an HtmlPage object however all
of them are Page objects. Thus you have to typecast accordingly.

Check the following code wchich returns the source as String according to
the type of the response.

Page pageSource = webClient.getPage("http://example.com");
String  pageSourceString = getPageSource(pageSource);

public static String getPageSource(Page page)
{
if(page instanceof HtmlPage)
{
return ((HtmlPage)page).asXml();
}
else if(page instanceof JavaScriptPage)
{
return ((JavaScriptPage)page).getContent();
}
else if(page instanceof TextPage)
{
return ((TextPage)page).getContent();
}
else //page instanceof UnexpectedPage
{
return ((UnexpectedPage)page).getWebResponse().getContentAsString();
}
}

>From the above example you can see that there are 4 different types of
Pages that  webClient returns.

The method used here returns the string of the source however you can
modify the code to your needs according to the instance is returned.
