any way, I am a Java programmer and I want learn about J2ME but I don't know where to start , MIDP , CLDC .....
just give a point to start (online tutorial, examples,...).

HI

Download Sun's WTK and use it to develop the MIDlets. Rest assure what u find in Sun's WTK will always be there on the devices.

If you want to use the specific libraries that the carriers provide then u can add them to your build process. For eg, Nokia has the Nokia UI library.
I do not know if Samsung has any particular libraries. Sprint provides its own library for all devices on the Sprint network ( including the Samsung that they carry)

As for tutorials... there are several of them on the web... i suggest getting a good book and reading the first 3-4 chapters ... rest you can learn on the way.

Not necessarily. The GCF (network API) and MMAPI (multimedia API) implementation in SUN WTK is often different from devices. Also, the screen resolution, memory requirement and softkey mapping are all different for each device. The WTK is good for learning and prototype development. But to develop real world apps, use a vendor provided SDK. Forum Nokia has many Nokia device SDKs.
