Hi anne:

change service base to whatever you want, eg

 <service name="gridftpServer" serviceType="GridFTP" base="gridftp://server:port/"; 
/>

see:

 
http://www.unidata.ucar.edu/projects/THREDDS/tech/catalog/InvCatalogSpec11.html#constructingURLs

You should print out and read that whole spec, then things should be clearer.

Hi Ethan and John,

I just noticed that the access URLs I'm getting all start with http regardless of the methods of access I've determined in my code. I've copied some results from the http rendering below, and attached my code that determines and sets the access methods. Am I doing something wrong?

If either of you are available to help me with this ASAP, that would be especially great, although I know the timing is bad for both of you.

Thanks!

Anne
