Minimal BD-J SDK

Post Original
With the recent news of being able to launch Java games from PS3, FreePlay has stepped up released a minimal BD-J SDK for all you homebrew enthusiast.

In lieu of this we have also opened up a new BD-J section, we urge anyone that is cerating a BD-J homebrew to upload and post it here. We will front page all the BD-J apps created weekly (they must be however uploaded to downloads section).

There are many homebrew possiblites with BD-J, silenoz has already coded a very small and quick RSS reader for NY Times using the PS3's internet connection. You can download that here.


README:
BD-J for PS3 minimal devkit by FreePlay

NOTE: For this to work properly, you *MUST* copy it to the root of your C: drive - that is, to C:\bdj-ps3. DO NOT rename the folder.

Included is everything you'll need to get started except for:
1. a working installation of JDK, the Java Development Kit (get that from Java SE Downloads - currently, the latest version is JDK 6 Update 7)
2. a copy of bdj.jar, the BD-J API. I can't provide this, since you need a license to use it; however, if you have a PC program capable of making or playing Blu-Ray discs - like Nero or PowerDVD - you can get this file from there. (In Nero 8, the file is located in C:\program Files\Common Files\Nero\NeroBLC\BDJ\jl ib .)

I don't have any real documentation on BD-J, though I'm sure you can find some on the HDCookBook website. In the 'docs' folder is some basic info on BD-J on a very high level.

So far as I can tell, there are some pretty strict limitations on the PS3's implementation of BD-J:
1. You cannot read or write local files.
2. You cannot list the contents of a directory.

I may be wrong, so feel free to correct me, but I ran a few tests and couldn't do those things.

I've also included a sample Hello World application and silenoz's RSS reader, as well as a build.bat file for building, packing, and signing the programs. This batch script is pretty much universal, unless you need to add in other JAR files for your compilation.

Source files for each project should go in a folder called root\org\homebrew. For example, if you make a project called "Test App", in your "Test App" folder you'll place the universal build.bat , then make a root\org\homebrew folder and place your .java files in there. The 'root' folder will become the root of your JAR file; any files you place in that structure will become part of the JAR.

The 'disc files' folder contains the file structure for what you'll copy to your storage device. Once you've built your 00000.jar file, copy it to 'AVCHD\BDMV\JAR\' and you'll be ready to test it.

Good luck!

Finalmente han decidido en lanzar un SDK para que todo el mundo pueda crear aplicaciones java para la PS3:

Aquí os dejo el articulo oficial de PS3 Hax:

Con las ultimas noticias sobre ejecutar juegos java desde la PS3, FreePlay a lanzado un SDK del BD-J para poder programar aplicaciones java compatibles con nuestra PS3.

Con razón a esto hemos abierto una nueva sección para que postees las aplicaciones que has creado para PS3 (nosotros no, si no los de PS3 Hax)

Con el BD-J se nos abre un mundo de possibilidades a la hora de crear Homebrew, silenoz a programado un pequeño y rapido lector RSS del NY usando la conexión de Internet de PS3.Lo puedes descargar aquí: http://www.megaupload.com/?d=4ALH2RU0

BD-J for PS3 minimal devkit by FreePlay

NOTA: Para que esto funcione correctamente, debes copiar la carpeta a la raiz del disco duro C. Quedaría una cosa así: C:\bdj-PS3. NO renombres la carpeta

Se incluyen todas las cosas necesarias para que empiezes a programar excepto:
1. El Java Development Kit (JDK) que lo puedes conseguir en la pagina principal de JAVA.

2. Una copia del bdj.jar, el BD-J API. No os puedo proporcionar esto, ya que necesitas una licencia para poder usarlo; sin embargo, si tu tienes un programa capaz de grabar o reproducir discos

Blu-Ray - como el Nero o el PowerDVD - Puedes conseguir estos archivos de aquí (En Nero 8, el archivo está en C:\program Files\Common Files\Nero\NeroBLC\BDJ\jl ib .)

I don't have any real documentation on BD-J, though I'm sure you can find some on the HDCookBook website. In the 'docs' folder is some basic info on BD-J on a very high level.


Hay unas cuantas limitaciones a la hora de usar la funcionalidad BD-J:
1. No puedes leer o escribir archivos locales.
2. No puedes ver los archivos de un directorio.

Quizás me equivoque,así que sois libres de corregirme, he hecho unos cuantos tests y no he podido hacer esas cosas

I've also included a sample Hello World application and silenoz's RSS reader, as well as a build.bat file for building, packing, and signing the programs. This batch script is pretty much universal, unless you need to add in other JAR files for your compilation.

Source files for each project should go in a folder called root\org\

Homebrew. For example, if you make a project called "Test App", in your "Test App" folder you'll place the universal build.bat , then make a root\org\

Homebrew folder and place your .java files in there. The 'root' folder will become the root of your JAR file; any files you place in that structure will become part of the JAR.

The 'disc files' folder contains the file structure for what you'll copy to your storage device. Once you've built your 00000.jar file, copy it to 'AVCHD\BDMV\JAR\' and you'll be ready to test it.

Buena Suerte!!
