I need to do a http get to download files on a server that is using authentication so I am trying to use the [setDefaultAuthenticator](http://docs.oracle.com/javase/7/docs/api/java/net/Authenticator.html#setDefault(java.net.Authenticator)) method of java.net.Authneticator. To do this I will need to override the [getPasswordAuthentication](http://docs.oracle.com/javase/7/docs/api/java/net/Authenticator.html#getPasswordAuthentication()) method of the Authenticator class.

My problem is that I have no idea of how to do that in script. Can anyone provide a simple example of overriding a method using scripting within Ignition?

This seems to have done the trick:

```auto
username = "someuser"
password = "apassword"

class MyAuthenticator(Authenticator):
    def getPasswordAuthentication():
        return PasswordAuthentication(username, password.toCharArray())

m = MyAuthenticator()
```

The way to override a method apparently is to subclass the existing class with the original method in it; add a method to your subclass with the name of the method that you want to override. And then of course instantiate an instance of your subclass.
