Hello Pauline,
have you tried the latest TDS 4.3.15 version?
There were some issues in 4.2.10 version handling datasets without time
dimension that were fixed in 4.3.
Cheers!

Hi all,
I'm experiencing problems with a GetFeatureInfo request on THREDDS.
Here's the setup details:
java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.5) (6b24-1.11.5-0ubuntu1~12.04.1)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)
THREDDS Version 4.2.10 - 20120417.2151
Tomcat 7
I'm getting a null pointer exception when I make a GetFeatureInfo request for
the CARS dataset, e.g.
http://thredds.aodn.org.au/thredds/wms/climatology/CARS/2009/silicate_cars2009.nc?LAYERS=mean&ELEVATION=0&TIME=2013-01-22T10%3A48%3A24Z&TRANSPARENT=true&STYLES=boxfill%2Frainbow&CRS=EPSG%3A4326&COLORSCALERANGE=-50%2C50&NUMCOLORBANDS=20&LOGSCALE=false&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetFeatureInfo&EXCEPTIONS=XML&FORMAT=image%2Fpng&BBOX=-180%2C-133.125%2C180%2C148.125&I=228&J=242&INFO_FORMAT=text%2Fxml&QUERY_LAYERS=mean&WIDTH=512&HEIGHT=400&url=http%3A%2F%2Fthredds.aodn.org.au%2Fthredds%2Fwms%2Fclimatology%2FCARS%2F2009%2Fsilicate_cars2009.nc&server=http%3A%2F%2Fthredds.aodn.org.au%2Fthredds%2Fwms%2Fclimatology%2FCARS%2F2009%2Fsilicate_cars2009.nc
I get the following exception in threddsServlet.log (with all *wms debugging
turned on)

Interestingly…. If I downgrade the Java version to 1.6.0, it works fine. Has
anyone else seen this problem? I've searched the mailing list, but failed to come up
with anything useful. Only seems to be an issue with the CARS dataset, and does work
for, maybe one or two variables, but the majority is not working. A fix for this
would be great, but I can run Java 6 for now. The dataset can be downloaded here:
http://thredds.aodn.org.au/thredds/catalog/climatology/CARS/catalog.html
I've tried something else too. If I run ncWMS-1.0, using Tomcat 7 and Java 7
(on laptop, running Mac OS X), GetFeatureInfo works properly!
I'm really stumped for ideas, so any suggestions would be a great help.
Cheers,
-Pauline.
