Hi All,

Is it possible to get the source code for opendap-java? I can't seem to find
it. I'm having some issues with configuring a proxy for opendap when using
netcdf-java and was hoping the source would help me get to the bottom of
it.

Specifically, when I open a opendap url via netcd-java using:
ucar.nc2.dataset.NetcdfDataset.openDataset(url);
I think somewhere along the call chain it's using opendap.dap.DConnect2.
(Please someone correct me if I'm wrong!) The only HTTP method call in
DConnect2 is GET (e.g. org.apache.commons.httpclient.methods.GetMethod).
However it appears to be making a HEAD calls too even though HeadMethod is
not called directly. Also, is HTTP HEAD required for the DAP 2 spec?

Also, is anyone interested in updating opendap-java to use an updated
version of Apace HttpClient  in opendap-java? It's currently using 3.x but
theres a 4.x branch at http://hc.apache.org/ with the admonition of:

Commons HttpClient 3.x codeline is nearing the end of life. All users of
> Commons HttpClient 3.x are strongly encouraged to upgrade to HttpClient 4.0.


Cheers

-- B
