Difference in behaviour of a class from executable jar and main method

[anees ahamed]

Hi,
I am attaching a java source here. I have a single question in connection with this class.
As you can see in the main method of this class, I give a username and password as credentials. When I execute this program from the main method I get correct output. ie; 'usrname','pwd' combination gives its corresponding output and 'usrname1','pwd1' give its corresponding output.

But, when I access this class from the application(executable jar), 'usrname','pwd' gives its corresponding output and after that if I give 'usrname1','pwd1' combination, it give the output corresponding to 'usrname','pwd'
Here is my simple Java class.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.Authenticator;
import java.net.MalformedURLException;
import java.net.PasswordAuthentication;
import java.net.URL;
 
public class GetAuthenticatedData
{
public String address;
public GetAuthenticatedData(String address){
this.address = address;
}
public String sendRequestString()
{
    System.out.println("Inside constructor");
Authenticator.setDefault(new MyAuthenticator());
    String str = null;
    try {
        URL url = new URL(address);
        BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
        
        while (( str = in.readLine()) != null) {
        System.out.println("string returned by server is "+str);
        return str;
        }
        in.close();
    } catch (MalformedURLException e) {
    System.out.println("e1"+e);
    } catch (IOException e) {
    System.out.println("e2"+e);
    }
    Authenticator.setDefault(null);
return str;
}
public static void main(String args[]){
GetAuthenticatedData at = new GetAuthenticatedData("https://" + "usrname" +":"+ "pwd" + "@www.mybooo.com/core/Dd002wW.php?data={action:'contacts',args:''}");
at.sendRequestString();
}
}
class MyAuthenticator extends Authenticator {
public MyAuthenticator(){
getPasswordAuthentication();
}
protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication("usrname", "pwd".toCharArray());
}
}

I really wonder how it behaves differenly when used independently and when used from an executable jar.
Please provide some help in this regard.

Hi there,

Can you show us the output of the running program? (I see you have System.out statements there). Also I don't see you validating that the arguments you pass in are really what you expect, it looks like you pass the args[] directly to a PHP call?
