Default Handset application proxy handling

Please Login to Remove!

Hi guys,

I have an application that makes a http connection to a server, this works fine. The connection now must be made to a server that is behind a proxy. I've read in java you can use the Authenticator class to handle this. There are a few examples here and here.

My Code:
ProxyAuthenticator() { 
this.user = "user"; 
this.password = "test";

  public PasswordAuthentication 
  onAuthenticationChallenge(String description, boolean isUserIdRequired, boolean isFullAccess) {
    return new PasswordAuthentication(user.getBytes(), password.getBytes());
  public byte[] onAuthenticationResponse(byte[] userName) {return null;}
The problem seems to be that in the Blackberry environment, you can't tell the sytem what to do when it is queried by a proxy:
and put these lines of code before your code opens an URLConnection-

Authenticator.setDefault(new ProxyAuthenticator("user", "password"));
System.setProperty("http.proxyHost", "proxy host");
System.setProperty("http.proxyPort", "port"); 

Now all calls will successfully pass through the proxy authentication.
Can anyone tell me what you have to do to 'register' your authenticator implementation with the system?
