Java - php / passing parameters

Question

hi,
i am trying to set up a communication between my java app and a php skrip. i've done the following:
try {
URL url =
new URL("http://test.net/" +
"login.php");
URLConnection connection =
url.openConnection();
connection.setDoOutput(true);
PrintStream out =
new PrintStream(connection.getOutputStream());
out.println("username=" + URLEncoder.encode("test"));
out.println("password=" + URLEncoder.encode("9e07480f0e4952926e115f15bc50ec47"));
out.close();
DataInputStream in =
new DataInputStream(connection.getInputStream());
result = in.readLine();
System.out.println("result:" + result.toString());
in.close();
} catch(MalformedURLException mue) {
System.out.println("Illegal URL: " + mue);
} catch(IOException ioe) {
System.out.println("IOException: " + ioe);
} catch(Exception e) {
System.out.println("Error: " + e);
the php gets my request but it doesn't realize the parameters username/passord.
is there a way to set the parameters through the api or do is the only way to do it by adding them to the url like ?username=bla&password=bla. i really would like to do it on a higher level but maybe there is no api support available. thanx for any advice, mischka.

Golden rule of testing: test one thing at a time.
Try it with this (working code) to test that you know that you CAN write a simple *.txt message file from a TextField first before extending it to verification /password whatever conditions.import java.net.*;
import java.io.*;
import java.awt.*;
import java.awt.event.*;
public class write extends java.applet.Applet implements ActionListener {  
    TextArea info = new TextArea(10,60);
     Button Bsend = new Button("SEND");
     String str = "", text="";
     public void init() {
          add(info);
          Bsend.addActionListener(this);
          add(Bsend); 
     public void paint (Graphics g) {
          g.drawString(str, 30, 270);
     public void actionPerformed(ActionEvent evt) {
            if (evt.getSource().equals(Bsend) ) {
            try{
                writePage();
               catch(Exception x){ System.out.print(x); }
          repaint();
    public void writePage() throws Exception {  
        text = info.getText();     
         URL url = new URL("http://"+getCodeBase().getHost()+"login.php");
            URLConnection conn = url.openConnection();
            conn.setDoOutput(true);
            OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
            wr.write(text);
            wr.flush();
        wr.close();
        str = "Information sent to " + getCodeBase().getHost().toString();
}
