HI,

I need to create Route maps dynamically, the data available
is in GIS format, i am trying to create it using servlets,
I am planning to createImage of map and then draw on that image getting the x, y coordinates from Gis...dbf file.

I tried to draw the Image first using toolkit to getImage and getGraphics to draw line on the map.... but i am getting error ...

Error:
getGraphics() only valid for images created with createImage(w, h)

can someone suggest the right way to do this


Thanks,

Hema
