Thanks for the prompt replies Perry and Bart!
I found part of my problem was that the TNS_ADMIN variable was not being
recognized so mapserver was not finding my tnsnames.ora. Having
corrected that, I now get the correct coordinates in the response, but
it 's not finding any features. This is mapserver 4.8.3 (on RHEL WS4)
running against an Oracle (10.1.0.4) spatial data source.
Here's my current request and response. I expect to find 67 point
features w/in this particular geographic extent, but the
featureCollection is coming back empty. The complete
DescribeFeatureType response is listed at the bottom of the message.
Thanks again for your help!
