simulate form type=button press with java application

[redmoonzer01]

I made a website that uses html and javascript to require log in.
Now i wanted to make a Java application to log in ... instead of using a browser
with a browser you would enter your name in text field and click Login

I use HTTPClient Emulating HTML Forms

now i use NVPair to send the form data for the text field
but it just sits there

i am thinking my problem is: I am not pressing the button
I don't know how to set up a NVPair to simulate the button press

I use InputStream and BufferedReader to read the page
When i do that i seem to get the html code sent to me

When you log in you get to a page that says you are in
If i get the html code that says YOUAREIN i would know it worked

but i am only getting the html code for the login page

so i am thinking i am just filling out the form and not submitting it

ok now i am using apache HttpClient

i am getting same results

i submit the form data
and get response of null

they say something about how you need to check cookie to see if logon worked

but my method of log on is just a html form with javascript that if you log on correct you get directed to a new site
... don't think cookies are even involved

so i was hoping i could send the log on data ... then read the resulting page but what i read is NULL
