I am trying to log into this website with the latest version of commons 4.0.1
and can't seem to get it to work. I checked the forum and all the posts seem
to reference the older version. Here is my code please help me out .
First the form on the page I am trying to log into
<div class="loginPanel">
<div class="container">
<div class="title">Login</div>
<form id="loginForm" class="loginForm" method="POST"
action="/path/to/main/page/login">
<table>
<tr>
<td class="label">USERNAME:</td>
<td><input
value=""
class="edit"
id="txtUsernameLogin"
name="txtUserName"
type="text"/></td>
</tr>
<tr>
<td class="label">PASSWORD:</td>
<td><input
value=""
class="edit"
name="txtPassword"
type="password"/></td>
</tr>
<tr>
<td colspan="2" align="center">
<input type="checkbox" name="txtRemember"
value="true" align="middle"/>
Remember me on this computer
</td>
</tr>
<tr>
<td></td>
<td class=""><input type="submit"
class="submit"
value="Login"
alt="Login"/></td>
</tr>
</table>
</form>
</div>
</div>'
Now the code I am using to try and log in.

if (cookies.isEmpty()) {
System.out.println("None");
} else {

}
}

}
} catch (URISyntaxException e) {

} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return pageSource;
}
}
For some reason I can't seem to login. No matter what I do it takes me right
back to the login page. Any help will be greatly appreciated. Also please
note that I don't have control over the login form as it is on a third party
site that I am trying to pull some data off once I get logged in.
Thanks,
