Minimal BD-J (Java) Devkit for PS3

PS3 - Image 1Okay, FreePlay's been busy putting together a minimal SKD for BD-J development, and he's generously shared it to the rest of the young PS3 homebrew community.

What this release brings you is basically everything you'll need to get started, save for a couple of things:
  1. a working installation of JDK, the Java Development Kit (get that from http://java.sun.com/javase/downloads/index.jsp - 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 FilesCommon FilesNeroNeroBLCBDJjl ib .)
There's also an included sample Hello World application as well as silenoz's RSS reader and a build.bat file for building, packing and signing the programs. He says that the batch script is pretty universal, that is unless you need to add in other JAR files for your compilation.

While this brew is looking pretty good, there have been found some pretty strict limitations on the PS3's implementation of the BD-J:
  • You cannot read or write local files.
  • You cannot list the contents of a directory.
Well, it could be that it just didn't work for him when he tried it, but that's why you'll have to give your feedback when you try this yourself. Maybe you'll have better luck.

Oh, and do take note that 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.

There are more instructions and details to be learned, so make sure  you do read and understand the readme as soon as you download the file, and before you try it out. Thanks, FreePlay!

» *NIX version

I've made a modified version of this devkit for *NIX environments (like Linux). The same rules still apply (requires the Java SDK and "bdj.jar").

» Blu-ray Burner

They are actually coming down in price. I bought a pre-installed external burner off of ebay. The exterior case was from Galaxy Metal Gear, and the drive inside was manufactured by LG. The model of the drive is GGW-H20L. I payed $299.99 + 19.99 for UPS Ground shipping. I own a lot of content which I have on DVD/DVD9 that I would like to have on only one disc. The discs are the part that are still expensive. This is the cheapest place that I have found for disc prices + combined shipping.

Sorry, the link for the site that I buy my BD-R/BD-RE was not submitted into the text. Do a google search for ACCA Products.
