The preliminary good news: I am able to use java events without java
coding (other than one fixed java bit). I have tested the java media
player and once the song is over, the pascal event is fired successfully :)
The fixed bit of java code can handle any event with any signature from
any object. I have some minor but time consuming hurdles/bugs to
overcome, but once done, only pascal coding will be needed for any java
