Summary: Using HtmlImageInput

Initial Comment:
Hello,

Can any one tell me how to use the HtmlImageInput to 
submit the form?

I can read the form from the web. e.g
final HtmlForm form = page1.getFormByName
("loginform");

final HtmlTextInput userName = (HtmlTextInput) 
form.getInputByName("txtLoginName");

userName.setValueAttribute("my name");

but the following i'm not sure is it the right way to get the 
object instance?

assumption the image name called "Login"
form method = post, action='login.asp"

the image tag like <input type="image" name="Login" 
src="../images/content/login_button.gif" value="Login" 
border="0" WIDTH="56" HEIGHT="16"> 

when click it will submit the form. In general the web 
page is host on 3rd party location and they will not give 
any support for this instance.

final HtmlImageInput login = (HtmlImageInput) 
form.getInputByName("Login");

Since the login is a image.

and i try to get the response from the page.

final HtmlPage page2 = (HtmlPage)login.click();
WebResponse resp1 = page2.getWebResponse();

it will throw the exception but the error message is null.

Can anyone help me?

Many thanks.....
Jeff

The exception is occuring inside commons-httpclient.  The
version of httpclient that shipped with HtmlUnit 1.2.2 was
2.0alpha3.  They have just released 2.0beta1 which fixes a
large number of bugs.  Please try beta1 to see if this fixes
your problem.
