HttpClient (Apache) - online Login

Hi,

I'm trying to login on an internet Page. I've been googeling and trying to find the right way to achieve this. What i got this far is:

I'm using the Apache package (HttpClient, Code, Logging).

import java.io.*;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.cookie.CookiePolicy;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.Header;

public class TestCode {

	static final String loginSite = "****";
	static final String checkSite = "****"; 
	
	public static void main(String[] args) throws Exception{

		HttpClient client = new HttpClient();

              cient.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
		PostMethod post = new PostMethod(loginSite);

		post.setRequestHeader(new Header("User-Agent", "****"));
		
		post.addParameter("name","****");
		post.addParameter("password","****");
		post.addParameter("button_name","****"); //<--Press Button?
		
		client.executeMethod(post);

		
		BufferedReader in = new BufferedReader(
				new InputStreamReader(
						post.getResponseBodyAsStream()));

		String decodedString;
		
		while ((decodedString = in.readLine()) != null) {
			System.out.println(decodedString);
		}
		in.close();
				
		post.releaseConnection();
				 
	}
	
}

This is the Internet Packe i'm trying to log in:

<<pre lang="xml">form method="post" name="post_name" action="TMP.php">
    <table cellpadding="1" cellspacing="1" id="login_form">
        <tbody>
            <tr class="top">
                <th>Enter Name:</th>
                <td>
                    <input class="text" type="text" name="name" value="Login_Name_Here" /> <span class="error"> </span>
                </td>
            </tr>
            <tr class="btm">
                <th>Enter Password:</th>
                <td>
                    <input class="text" type="password" name="password" value=""
                    maxlength="20" /> <span class="error"> </span>
                </td>
            </tr>
        </tbody>
    </table>
    <p class="btn">
                <input type="image" value="login" name="button_name" onclick="xy();" id="btn_login" class="dynamic_img" src="img/x.gif" alt="Login-Button" />
        <input type="hidden" name="w" value="" />
        <input type="hidden" name="login" value="99999999" />
    </p>
</form>

In the response i get, the password & name is fild in.

I'm not sure if i have to "press" the Button or not.

Also wenn i get the response i'm still on the login page (name & password ist fild in the under "value").

Usually when i login on my browser the i-net page sends me to an other page
(Just changed the page: TMP.php).

Anyone has a clue?

Thanks in advance.

Ok, it's me again,

right now i'm trying on an easier example. No login!
But still i don't get the PostMethod...

What works & and what i understand is the GetMethod:
http://hc.apache.org/httpclient-3.x/tutorial.html
-> I get the information of the internet page.

But what doesn't work still is the PostMethod:
http://hc.apache.org/httpclient-3.x/methods/post.html
-> Here I get the same information (like with GetMethod)

Has anybody a working PostMethod example on an excisting internet page??

Any help is appreciated
