Jason/Chris:
First of all I want to thank you for the prompt responses.  Unfortunately, after struggling with MapGuide all day yesterday, I have still been unsuccessful in my attempts to display ECW files in 2.1.  To summarize what I did:

1) I do have my imagery in an alias folder and I did  it reestablish this folder after installing 2.1 then restarted the service.  If I create a data connection from this alias folder using JPG and JGW files, it works fine.  It is with ECW files that it fails.  As a simple test, I go into Maestro, create a data connection pointing to a folder containing JPGs and JGWs, and then if I click the "Preview this item" button.  I then get a webpage which will allow me to see a list of all the JPG files it has recognized.  If I do this with ECWs on 2.0.2 it works the same way, but with 2.1 it returns an empty list every time and does not display those ECWs on a map. 

2) I have placed the files contained within the gdal_wavelet_3.4.zip file into my MapGuide installation in the appropriate bin and fdo directories.
3) I downloaded the ECW Support DLLs and copied in the four NCSxxx.dll files into the fdo directory of the MapGuide installation and then restarted the service.

At this point I am still unable to display ECW files on the map and, in fact, as I mentioned in (1) Maestro does not recognize ECWs as a valid data source through the "Preview this item" function (though this works for JPGs and worked for ECWs in 2.0.2).  I have even gone so far as to completely remove my installation of 2.1, deleting the directories and files left behind, then completely reinstalling from scratch, but to no avail.

I would greatly appreciate any more ideas anyone might have and would like to know if anyone has of yet been able to get ECWs to display through MapGuide 2.1.

If you're using an alias on the server to reference the folder containing the ECW's, is it still correctly configured now that you've upgraded?

It appears that since upgrading to 2.1 (from 2.0.2), the ECW raster images I

was previously using are no longer displayed on my map.  Is this due to the

FDO version changing from 3.3 to 3.4?  I have installed the files found at

that were working with 2.0.2 found at

http://trac.osgeo.org/fdo/wiki/FdoGdalNotes, but to no avail.



Has anyone had success displaying ECW files in 2.1?  I appreciate any help

you can provide.
