[OpenLayers-Users] A very simple application doesn't work

Wed Apr 4 11:12:44 EDT 2007

Hi Steve,

I assume it is working with the Layer/Mapserver class, only that the site is
still empty. I looked at the address of the map in the the properties window
- the part of it that as I suspect prevents it from working is the
mapextent, which is set to -180 -90 180 270 (initial maximum extent).
Setting up the extent via OpenLayers didn't bring any success neither over

var wms2 = new OpenLayers.Layer.MapServer("BGL Abschnitte", "
http://localhost:8080/cgi-bin/mapserv.exe?map=/ms4w/apps/test/htdocs/test.map",
{mode: 'map', layers: 'Flaeche', mapext: '2574985.815002 5646323.449916
2587295.900005 5655021.169988'});

nor over

var bounds = new OpenLayers.Bounds(2574985.815002, 5646323.449916,
2587295.900005, 5655021.169988);
map.zoomToExtent(bounds);

Could there be still something I'm doing wrong?

Cheers,
Dmitri
