Is Blu-Ray java based?

[Dave]

I saw this:

The only thing of Blu-ray that's clearly inferior to HD DVD is that the software is JAVA-based, which makes the players slower than they could've been (JAVA needs a lot of processing power).

Can someone brake this, i need to reply to this user

Yes Blu Ray is Java based.
Sun Microsystems is going to be devistated by that news. Sun developed Java to be platfrom independant and ideally suited for small dedicated hardware applications - especially microcontroller applications, that are dedicated computers designed as I/O specialists e.g. the controller for a fridge or washing machine and onto more complex functions as external Hard disk drive controllers. They are not very smart or powerful compared to their CPU cousins in the thinking or speed departments but have a host of other redeeming features.
As far as the way it has been implemented in Blu Ray I don't know, but it's initial design was for being small and very efficent.

I believe it is the interactive features that are based on a version of Java designed for Blu-ray. Both HD-DVD and Blu-ray use some form of interactive language to allow for the interactive features that are capable on their discs.

There is no specific justification that anyone has ever had that would ever show justification for the statement that you read. Java is what runs on cel phones to play video games. It is hardly a 'resource' hog. In fact, because it is a fairly well matured interactive technology with strong usage in many types of devices from phones to PCs, it is far more likely to be stable and well used within the Blu-ray platform.

So, it is just as feasible to say "HD-DVD doesn't use Java which is well established, has many of programmers already out there, and has proven itself as a solid language for interactive features. HD-DVD instead chose to go with a far less versatile and proven technology."

I don't believe the above statement either. I think the interactivity of both formats is fine and totally meaningless in the grand scheme of things.

Blu-ray isn't Java-based, but BD-J (the advanced content platform) is. That means discs may include content which makes use of Java, but they don't have to (none of the first release titles do). BD-J is required for accessing the network connection, among other features.

BD-J is based on the same Java Micro Edition (Java ME) platform as OCAP and MHP. OCAP is the cable standard which will be a part of most cable settop boxes and built-in to many televisions starting later this year, and which will provide interactive support for broadcast and cable television (i.e. voting for American Idol through your TV rather than your phone). MHP is similar, and is widespread in Europe and parts of Asia. Java ME is also what is built in to 80% of all new cellphones worldwide.

People referring to Java as "slow" are either uninformed or have an anti-Java agenda. While the early releases of Java were certainly slower than native code, the optimization technology available today has eliminated this problem, and Java applications on PC's and servers generally run as quickly as other high-level languages (i.e. C++). The Blackberry is also a purely-Java based device (the OS and the apps), yet no one complains that it is slow...

BD-J is going to open up some wonderful oppurtunities for content creation.

Yes, like enabling BD authors to rob us of the really fun features we took for granted with our DVD players, like zoom and slow motion.

The only way around this is spend money on software and BD-RE blanks and time and effort to hack the disc, since the BD Association successfully forced all player makers to add Oracle's Java chip. Once again, collectors and enthusiasts get screwed by the profiteers, intentionally or not.
