Ok, thanks for clarifying this.

WMS-connetion is now working, but results are...hm...something I did not expect.

This is an example map I get when using OpenLayers client on PC, the figure of Finland when using epsg:3067:

And this is what I get with MaemoMapper:

Could this be a problem between MaemoMapper and Proj? Or should I just change some parameters somewhere?

Oh, I just found this from http://hoohol.ath.cx/public/index.ph...eMM-Extensions

"Tiles don't seem to fit exactly, what can I do?

Not much, sorry. In this case the projection is sufficiently different from the mercator projection and one would need real warping for a fix. Lower zoom levels usually decrease the errors. (For warping look at gdal)"

If this is true, which epsg code correspods mercator projection that Maemo Mapper uses? I can use gdal and proj on server side and hopefully create MM compatible WMS-service.
