Microsoft paint..
2) After that two from diffrent mechine(connected by the network) will communicate the same interface of this whiteboard..

From where i can get the reference. How i start this project..?

At a guess I would suggest you need to be look at the Java2D package, and the network package.

you might also want to look into compression, because bitmapped graphics produce large datasets.

An aternative, and probably better suited to your application would be to use vectors, much like corel Draw and Adobe Illostrator.
Vectors are just some "maths" that describe the line between point a and point b, so rather then transmit the whole line you just transmit its start and end point. Of course this is easy for stright lines, but much more difficult for free hand lines.

Just some thoughts
