Dennis,
Thanks for quick reply. I only did some hacking (I used to work for
Hacker, Peter the Great-:)
here is what I did on DConnect2.java

HttpMethod;
methods.GetMethod;
HttpClient;
MultiThreadedHttpConnectionManager;
HttpMethod;
Header;
auth.AuthScope;
UsernamePasswordCredentials;
methods.HeadMethod;

setCredentials(
user", "passwd"));

MAuthenticator());
197d183
MAuthenticator());

Similar thing to NetcdfDataset.java

Hi John,
Sorry if this is not the right place to post this message.
I have problem to use netcdf java (along with opendap.jar etc) to access
a remote data (via opendap) that requires basic authentication. Basic
authentication does not provide security to the dataset ---but just a
sort of limitation for public access. For example, a group researchers
want to share datasets that are still under QC, and they certainly want
to make sure it is not perceived as data product for all. Anyway popular
data analysis software like GrADS and Ferret can all handle URL like
http://usr:pass@... to read data. And that was the way I set up servers
while I was in Hawaii. Right now, using matlab (if it calls use netCDF
java lib) application and GISS Panoply can not read opendap that requires
basic authentication. It seems to me that opendap-2.2.jar (by OPENDAP
group) and netcdf-4.2.jar (by UNIDATA group) (specifically
opendap.dap.DConnect2 and ucar.nc2.dataset.NetCdfDataset ) need basic
authentication credential enabled.
I have fixed the problem but it is rather ugly -:) for distribution. I
wonder if you developers can put this feature in your development or if
there is any tip to share with me that it can be handled in the main
method (like to create a static httpClient object that can take care all
the authentication challenge all the way down to the lib.
Many thanks..
