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.
