Re: [thredds] URL pattern to access NetCDF-Java ToolsUI?

Thanks, John. I was looking into this for the purposes of injecting a Tools
UI URL into ncISO's output in TDS. It is my understanding that ncISO does
not have access to the TDS catalog URL, and it sounds like Tools UI needs
that (without extra fiddling with JNLP files, etc.). No biggie. Thanks
anyways.
Cheers,
John Maurer
