Hi John,

I have set up a new unidata agg server at
http://www.ferret.noaa.gov:9090/dodsC.
I am receiving an error when I try to access the NcML.xml file:
-----------------
Error { code = 5; message = "CatalogServlet ERROR opening NcDataset

2 parts of the tomcat catalina log show:

The NcML.xml file is an exact copy of what was working before, I simply
changed the name (also in the catalog.xml file).
I have been through the dodsC/debug page.  I have tried to find the
error in TOMCAT documentation  The only difference that I see is that
the version of java on the machine stout is
j2sdk1.4.0
and the version on machine ferret is j2sdk1.4.1_01

I'm stuck, any ideas?

Joe
when i look at the debug "show acccess URLs", i get as the internal access path: 

file://WEB-INF/dodsAS/NDBCstdmetNcML.xml
try using an absolute file path with file:/// ; i dont really understand where tomcat puts the working directory, and i think they have changed it in different versions. once you get that working, you can experiment with reletive paths if you want.
