Re: [netcdf-java] [Support] Opendap java



Brian,

The Java implmentation of the DAP is not under active development. It is available through our subversion server here:

   http://scm.opendap.org/svn/trunk/Java-OPeNDAP/

It is available for public checkout:

   svn co http://scm.opendap.org/svn/trunk/Java-OPeNDAP/

If in your endeavors you find that you can improve it we would be happy to look at including your changes/updates.


Thanks,

Nathan

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
