[mapserver-users] Mapplet

Wed May 8 20:05:17 EDT 2002

I've installed the Mapplet java class. I have managed to get it to the point
where it will draw a box on the map, but that's about it.  It refreshes the
area of interest box but does not update or zoom to the new extent on the
map.  I'm new to java applets and am not sure how to proceed.  Obviously, I
want to link it to the zoom function, but I've either missed a step or just
set it up incorrectly.  Below is my template html.  Any help would be
greatly appreciated.

  document.mapserv.imgxy.value = minx + " " + miny;
}

function mapplet_error(message) {
  alert(message);
