client.executeMethod(get);

System.out.println("Login form get: " + get.getStatusLine().toString());

Cookie[] get_cookies = client.getState().getCookies();

if (get_cookies.length == 0)
{
System.out.println("No cookies after GET Method !");
}
else
{
for (int i = 0; i < get_cookies.length; i++)
{
System.out.println("- " + get_cookies[i].toString());

}
}

post.releaseConnection();

int statuscode = post.getStatusCode();

}


}

}
}


Thanks in advance..

it's possible the contents of the POST are incomplete, for example, some sites now use JavaScript to append additional values to a HTML form after it loads onto the screen (a dynamic html kind of thing). If you have the firebug plugin for and/or "HttpFox" plugins for Firefox, experiment with and observe the cookies and the net activity as you perform a manual login thru Firefox.

Thank you very much for ur reply..I have installed add on for jsp. If I disallow scripts globally then also I am able to login to web.de through mozilla browser. So I guess it is not using any jsp. Also I tried with "tamper" to login from browser. In that i noticed that it sends the same data through POST which I am passing in my code. By this I concluded that parameters I am passing is correct. and as far as cookies are concerned I dont get any cookies in my output. Also if I disable cookies I am able to login to the email account from the browser. Now if u have any other idea regarding this please let me know. I would really appreciate that. I am stucked here and dont know what to try next !!

Regards..
