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

Owner

I see, thanks Jon, I will try
