Hi John:
When TDS gets this URL:
http://oos.soest.hawaii.edu/thredds/view/ToolsUI.jnlp?catalog=http://oos.soest.hawaii.edu/thredds/idd/nss_hioos.xml&dataset=NS02agg
It creates a jnlp file which is sent back to your browser. If your
browser has Java webstart installed as a helper application (which
happens when you install Java on your computer), the jnlp file is
handled by the "Java plugin" on your browser, which downloads ToolsUI
from wherever the jnlp file specifies, currently:
"http://www.unidata.ucar.edu/software/netcdf-java/v4.3/webstart";
The jnlp file has been customized to include the command line argument
of the form "{catalog}#{dataset}", and the ToolsUI application looks for
this and uses it to open that catalog and display the named dataset in
the "Catalog Chooser" tab. This UI component gives access to all the
metadata and access protocols of that dataset.
Ok, I just had to write all that down to remind myself how it works.
ToolsUI will also accept a command line consisting of just the dataset
URL, and send it to the Viewer tab. You would have to create a different
Viewer / JNLP file to make this work from TDS, but Im not sure if thats
what you want to do?

Hi all,
By default, many/all TDS catalogs list the "NetCDF-Java ToolsUI
(webstart)" under Viewers. I notice that this is accessed via two URL
parameters: "catalog" and "dataset", for the TDS catalog page URL and
dataset identifier, respectively. e.g.
http://oos.soest.hawaii.edu/thredds/idd/nss_hioos.html?dataset=NS02agg
points to:
http://oos.soest.hawaii.edu/thredds/view/ToolsUI.jnlp?catalog=http://oos.soest.hawaii.edu/thredds/idd/nss_hioos.xml&dataset=NS02agg
I'm wondering if there is a way to access the ToolsUI with other URL
parameters? Specifically, is there a way to pass it an OPeNDAP URL
rather than a TDS catalog and dataset ID. e.g.
http://oos.soest.hawaii.edu/thredds/view/ToolsUI.jnlp?url=http://oos.soest.hawaii.edu/thredds/dodsC/hioos/nss/ns02agg
My tests using "url" or "opendap" parameters pointing to the above
OPeNDAP endpoint were unsuccessful at loading the dataset at startup.
Thanks!,
