[udig-devel] Re : Integrating Mapserver and uDIG.

[Jesse Eichar]

A couple of points about the browser catalog:
The issue where clicking on a WMS URL brings up a save dialog is fixed.
PostGIS URLS, WMS and WFS URLS are currently the only accepted URLS.   
But is is easy to add more.

Let me know if you have more questions.
