The problem is that in this case we need to provide a client
certificate. If we could get a handle to the HttpClient object (which I
think is used to make HTTP calls under the hood?) we could probably set
it up to perform the handshake.
ok, i think this is orthogonal to the https: issue.
Basically you have to make an HttpClient object and pass it in to
various classes. You can use HttpClientManager to create one, or make it
yourself. Here is the standarad init sequence used in ToolsUI (GUI):
CredentialsProvider provider = new
thredds.ui.UrlAuthenticatorDialog(frame);
HttpClient client = HttpClientManager.init(provider, "ToolsUI");
opendap.dap.DConnect2.setHttpClient(client);
HTTPRandomAccessFile.setHttpClient(client);
CdmRemote.setHttpClient(client);
NetcdfDataset.setHttpClient(client);
WmsViewer.setHttpClient(client);
caveats:
1) thredds.ui.UrlAuthenticatorDialog is for GUIs only.
2) we are in the midst of switching to use of HttpClient version 4,
which will affect the API, since the above HttpClient class is from
HttpClient 3.
we are considering how to make this easier to use, so suggestions are
welcome. We also have been waiting for this switch to HttpClient 4 to
tackle some outstanding problems, eg self-signed certificates, proxy
credentials, etc. we expect to switch in CDM release 4.2 (about a month
away). not sure how many issues we will have fixed, but at least we'll
be on the right code base.
I will add this info to the document at:
http://www.unidata.ucar.edu/software/netcdf-java/reference/HTTPauthentication.html
which is still useful as background.
Cheers, Jon

Hi,
I am trying to access an opendap site over https using a certificate.
However, it is not working:

What would you recommend trying?

We are also modifying our code to allow https: in the dataset URLs.
