Hi Leakha,
> AS proposed in [another THREDDS inquiry GEC 600533], I'm using
> NetcdfDataset.openDataset, with my url containing the constraints

> 107_rad_b0702.nc.dods?latitude[0:1:680],longitude[0:1:840],rad[0:1:680][
> 0:1:840]). However it is still does not work and generates an error

NetcdfDataset.openDataset() will not accept constrained OPeNDAP URLs. There isn't a method in the netCDF-java API that will open a constrained OPeNDAP URL. The netcdf API can open unconstrained OPeNDAP datasets and when the netCDF API is used to get subsets it will translate that into OPeNDAP constrained requests. Those requests return the subset of data via OPeNDAP and the netCDF library translates that into netCDF API objects in memory.
Hope that helps,
Ethan
