Hello!
I have a problem with Mapserver which I am apparently unable to solve. I
have a mapserver installation which is queried by a web component, that
uses virtual earth tile addressing. It works really great. My web
component queries it like this:
http://localhost/MapServ/mapserv.exe?map=mymap.map&mode=tile&tilemode=ve&tile=1202213133323032212&layers=aaa
Until now it worked with ECW files only, and I had no problems. But now
I need to add a shape file, and I just can't get it to work! I googled
extensively the whole morning but I was unable to find any solution.
Ogrinfo says this:

**************************************************************
This map has the same extent as the ecw I am using and it was provided
by the same person, so I just thought to use the same projection as the
ECW. I also thought that the output projection should be the same as the
one I am using with the ECW, to work with the web component.
Unfortunately, all tiles I get are just blank, and calling mapserver in
map mode also renders a blank map.
If I comment out the projection inside the layer, calling mapserver in
map mode, it displays the map. But the tile is still blank.
I am probably using the wrong projection, but I really can't figure out
how to find the correct one, or how to translate the ogrinfo information
to the mapfile!
Here is the mapfile I am using.

Is there a way to display this shape on the tile?
Thanks for any help!!!
