Works great.   Only a few comments:

The WMS service emits more error messages if you try to feed it bad
arguments (ie. REQUEST=GetMap) vs. the WCS service.   The WCS service
silently fails by not emitting an error message or file.  Do something
bold like changing the version number from 1.0.0 to 9.0.0:

http://localhost:8080/thredds/wcs/testAll/2004050300_eta_211.nc?request=GetCoverage&version=9.0.0&service=WCS&format=GeoTIFF&coverage=Z_sfc&bbox=-134,11,-47,57

This causes a silent failure.  This makes for rough debugging of clients.

Changing the version in WMS from 1.3.0 to 4.3.0 causes a 404 error.

http://localhost:8080/thredds/wms/testAll/2004050300_eta_211.nc?service=WMS&version=4.3.0&request=GetCapabilities

This generates the desired error message:

http://localhost:8080/thredds/wms/testAll/2004050300_eta_211.nc?service=WMS&version=1.3.0&request=GetMap&layers=Z_sfc&crs=EPSG:4326&bbox=-135,19,-31,60&width=-50&height=400&styles=&format=image%2Fpng

<ServiceExceptionReport version="1.3.0"
xsi:schemaLocation="http://www.opengis.net/ogc
http://schemas.opengis.net/wms/1.3.0/exceptions_1_3_0.xsd";>

<ServiceException>

        Parameter WIDTH must be a valid positive integer

</ServiceException>
</ServiceExceptionReport>

Can still get a map if you change the service name to something arbitrary:

http://localhost:8080/thredds/wms/testAll/2004050300_eta_211.nc?service=YES&version=1.3.0&request=GetMap&layers=Z_sfc&crs=EPSG:4326&bbox=-135,19,-31,60&width=600&height=400&styles=&format=image%2Fpng

Anyways- using a well behaving client, this is all moot.  Unfortunately,
there is much variation between clients and versions they support.

The THREDDS Data Server version 4.0.06 is now released for testing. We
expect
to rapidly promote it
to be our stable release, but for now, do not replace your mission-critical
servers.  It has many
bug fixes and improvements "under the covers" that are not in the 3.17
stable
release.

Besides using the netcdf-java 4.0 library, the main new feature is the
addition
of an OGC WMS
service, thanks to our collaborators Jon Blower (Univ. Reading UK) and
Pauline
Mak (Australian
Research Collaboration Service) who did the hard work.


Get the new war file at:

  http://www.unidata.ucar.edu/projects/THREDDS/tech/TDS.html

There's a bit of learning to upgrade your configuration. Please see

 http://www.unidata.ucar.edu/projects/THREDDS/tech/tds4.0/UpgradingTo4.0.html

for more info.

We also have a 4.0 test server running on motherlode, which serves the NCEP
model data through WMS, at:

  http://motherlode.ucar.edu:8081/thredds/

this is (almost) a duplicate of our 3.17 production server at

  http://motherlode.ucar.edu:8080/thredds/


We would appreciate you trying this new version out and giving us feedback.

Thanks!
