This is a little rough around the edges but it works.

Hey Jon... do you know if this works with 2.2.4? I've gotten as far as:

accessToken = createObject( 'java', 'twitter4j.auth.AccessToken' ).init( 'myConsumerKey', 'myConsumerSecret' );

But get ->
Error: Invalid access token format
Type: java.lang.IllegalArgumentException

Fairly certain I've got twitter4j set up properly, as I can do a writedump( createObject( 'java', 'twitter4j.auth.AccessToken' ) );, which does dump me an object.

Thx!

Hello Jon, have the same question as Charlie.
I even tried to use javacast to be sure I'm passing java.lang.String keys as parameters, but still have the problem - "Invalid access token format"
Any ideas?
Thanks

No, I'm pretty sure it doesn't work with 2.4 and that's why you're getting that error. Try 2.1 and see how that works. I'd love to get around to fixing this but I haven't had the time.
