[OpenLayers-Users] How can I display a map with a position
changing marker.

In my case it is stored in WGS84 in separate columns.
To help geoserver a bit I created an extra column with a SDO_GEOMETRY
(using Oracle Spatial db) with EPSG:4326 projection and an extra column
with Dutch RD projection (filled with a trigger) because the rest of
the map is in Dutch RD projection and this way no reprojection needs to
take place.
Cheers Kris

There is another thing I want to know.
Which format is the Lon&Lat information stored in the mysql database? Is
this a standard?
