jbox2d

I have view, for example GameView which extends SurfaceView . I have integrated Box2D physics in GameView. I have two widths ,

GameView width, height and Box2D physics world width ,height. I need to get the position of box2d world with the GameView co-ordinates.

For example,

Total width of screen = 240 Total height of screen = 320

Screen points needed to be mapped onto box2d co-ordinates (x,y) = 127, 139

For this i need to get the max width and height of the Box2d physics world. Is there is any way to get the max width and height of Box2d world.

or

Can i limit the width and height of box2d world within the screen resolution.
