i am new to cdc, and has many mark ???? now i doubt wheather we can choose jsr184 API as the optional packages when we want to make cvm ?

because i saw many target cpu(OURS-PXA270-EP),can support 3d graphics function , the cdc doesn't have a optional packages of jsr184(M3G), so how can we make the cpu to run 3d graphic function? if we can using the jsr184, so where to download the jsr184 source code ? or if we need middleware , and what ?

if not, why i see many smart phone run 3d game, and using the winCE system ,how can they make it?

Many thanks!

Hi Hinkmond,

I saw in this post you mention MSA subset to be implemented two years ago. Is it ready now? I am also looking forward to having jsr184 and jsr135 for mobile applications.

PS: I am currently using Davy's build for cdc fundation dual stack, which has no jsr135/jsr184 supported now.

Sincerely yours, Vincent

Hi Winson,

You are correct that JSR 184 is not currently part of the current CDC
(phoneME Advanced) supported optional packages (JSRs) or code base, yet.

However, phoneME Advanced has a goal to include the MSA subset for our
in-process MR2 release (currently in development in the trunk).

For more info on the MSA subset, see:

http://developers.sun.com/techtopics/mobility/midp/articles/msaintro/

The MSA subset comprises eight JSRs (including JSR 184):

* JSR 139: J2ME Connected Limited Device Configuration 1.1 is the
configuration, which provides basic application support.

* JSR 118: Mobile Information Device Profile 2.1 is the profile,
which provides capabilities required by most mobile applications, such
as user interface.

* JSR 75: PDA Optional Packages for the J2ME platform specifies two
packages to support functionality often needed in personal digital
assistants, one for access to the device's local file system and other
for personal information management.

* JSR 82: Java APIS for Bluetooth gives you access to Bluetooth
functionality, and the OBEX protocol (conditionally mandatory).

* JSR 135: Mobile Media API provides access to media capabilities
such as audio and video playback.

* JSR 184: Mobile 3D Graphics API supports three-dimensional graphics.

* JSR 205: Wireless Messaging API profiles messaging features such
as SMS and MMS.

* JSR 226: Scalable 2D Vector Graphics API for J2ME supports
two-dimensional scalable vector graphics.

We expect full development of MR2 to complete within a year. Hope this
helps.
