Authenticator and logon

Question

Hi everybody:
I have a java problem and i think this forum is better than others so i post it here.
here is my senario:
I have a jsp based web applicaition. It will communicate will mainframe cics program through a cics class. Because cics ports are protected so end users need to input their own username and password. I use HttpUrlConnection to communicate with mainframe program and use Authenticator to logon. I use jsp to pass parameters(username and password) to the cics class.
But it seems only when system starts up, setDefault method will be called once. So system will use only one username to get access.
Am i working in the right direction? I've searched this forum but didn't find any solutions.
Any help is appreciated. Here is part of my code.
package com.lombard.Cics;
import java.net.*;
import java.io.*;
import java.security.*;
* CICS communication servlet.
* Send data to CICS, recieve data from CICS
public class CicsComm extends Thread
public void run()
communicate();
* Talk to cics
public void communicate()
data = new StringBuffer();
try
Authenticator.setDefault(new MyAuthenticator()); //set authenticator
System.out.println("http://" + CICS_ADDRESS + cics_port + CICS_PATH + cics_program + key);
URL u = new URL("http://" + CICS_ADDRESS + cics_port + CICS_PATH + cics_program + key);
HttpURLConnection quoteEngine = (HttpURLConnection) u.openConnection();
System.out.println(quoteEngine.getResponseMessage());
BufferedReader cicsResponse = new BufferedReader(new InputStreamReader(quoteEngine.getInputStream()));
String thisLine;
while ((thisLine = cicsResponse.readLine()) != null)
data.append(thisLine);
catch (Exception e)
data = null;
e.printStackTrace();
return;
class MyAuthenticator extends Authenticator {
protected PasswordAuthentication getPasswordAuthentication() {
System.out.println(username);
return new PasswordAuthentication (username, password.toCharArray());

I've received a couple emails on this, so I'll post the code:
URL url = new URL(myUrl);
URLConnection conn = url.openConnection();
// use the Encode class to base64 encode the username and password
// you can also us the sun.misc.BASE64Encode class if you haven't written your own
conn.setRequestProperty( "Authorization", "Basic " +
  Encode.base64Encode(username + ":" + password));This should get you past BASIC authentication on a URLConnection. I'm pretty sure you need to do this with every request you make.
