John,
I'm getting this error when my program tries to access a file over the network:

Looking at the NetCDF-Java User's Manual it would seem I have to "configure the server to set the Content-Length and Accept-Ranges:Bytes headers". It's not obvious (to me) how I do this. Can you point me to some documentation? I'm using Tomcat 5.5. 

Thanks,

Sheila
