Display coordinate upon a mouse click or duing mouse dragging

[Xiaopeng Xiong]

Hello List,

I wonder how to display the world coordinate when a user clicks on the map 
or drags a rectangle using mouse. I am quite ignorant to this type of 
programming.

I am using Mapserver and Rosa applet. But I can change to other 
configurations if necessary.

Your any suggestions or sample codes are appreciated!


Best regards,
Xiaopeng
