Getting involved with BD-J?

I am interested in delving into BD-J development but I'm not clear on what packages I need ( Java ME? Java TV? BDJ.jar ) or even if all of them are freely available. Does gaining access to the BDJ.jar package require me to buy a license from the BDA? I've been to "http://www.blu-raydisc.com/" and they are talking about massively expensive licensing; is buying a license from them necessary to gain access to the required libraries? Any insight is appreciated. Thanks.

No, the $2500 is for an evaluation license of the full BD-ROM
specification.

The javadocs and the compilation stubs are something we're working
on being able to provide. They'll be free.

Cheers,

Bill

Would I still need to down load the Java ME ( PBP ) package from Sun and add the BDJ.jar package as another dependency in my project? If a big part of the class libraries are coming from the Java ME ( PBP ) couldn't I download that from Sun and start development ( using the Xlet, graphic, etc... objects ) knowing that I wouldn't be able to create a Blu-ray disc until I obtained the BDJ.jar? Does the BDJ.jar contain its extensions and the Java ME ( PBP ) foundation? So many questions.... I've purchased the Cookbook but havn't gotten through it all yet and I am not certain it answers my questions fully but if you can clarify an of these that would b
e great. Thanks Bill.

I was hoping it would win out over the HD-DVD but given the BDA's stingy stance on the libraries I am somewhat disappointed. If they want the best tools they need to just open it up. Having great tools available to develop in will just further entrench their format. Let the free market drive who does or doesn't make money - not who can or can not afford their licensing. Just my 2 cents :)

Right now, the official answer is the $2500 "evaluation" license from
the BDA. We're working on making javadocs for the whole platform
available, and I think we're most of the way through the issues
with various lawyers (and for the record, not Sun lawyers :-) )
We hope to have this out in a month or two.

We're doing our best!

Cheers,

Bill

I've been really excited about the Blu-ray format because of its specs and the Java support being one of those. I was hoping it would win out over the HD-DVD but given the BDA's stingy stance on the libraries I am somewhat disappointed. If they want the best tools they need to just open it up. Having great tools available to develop in will just further entrench their format. Let the free market drive who does or doesn't make money - not who can or can not afford their licensing.

I just want to say that I wholeheartedly agree to every single sentence
in the above paragraph!

Check out latter part of conversation in thread

Apparently some of the guys in the gang agree with this - but it
apparently isn't easy to get things sorted.

Hoping for an exciting Blu future,
Kind regards,
Endre.
