Hi Ken-ichi,

I use the following code to add points to layers (parts coming from the 
gmap demo).
(with MapServer 3.6.2, it may be a little different with 4.0 ? )
The strange thing is that you have to go by :
$aLine = ms_newLineObj();
to add a point..., but it works.
You should find some help in it.

ps : by the way, are you using MacOs X ? Do you have the Safari web 
browser ?
I am looking for somebody with Safari on MacOs X that could check if the 
Rosa applet
can work (see any MapServer demo with the Rosa Applet), thanks.

code :...

//------ main --------
// $udl = name-of-layer (without 'shp' or 'dbf')
$oClickGeo=ClickGeo($nClickPixX,$dfWidthPix,$dfMinX, 
$dfMaxX,$nClickPixY,$dfHeightPix,$dfMinY, $dfMaxY);
$id=0;
point_add($oClickGeo,$udl,$id);
