I am having a similar problem. From a browser I can return ASCII data, so the OPeNDAP is working. http://...../thredds/dodsC/vault/..._cf.nc.ascii?crs,depth[3599:1:3719][19199:1:19319] If I try to access this through code, using http my log file fills up with msgs which suggests I can't use http (or something else needs setting ;-)):
I believe that the only way to do this via the Java API is to open the unconstrained URL (http://...../thredds/dodsC/vault/..._cf.nc) and then use the API to request the hyperslab you want rather than trying to open the constrained URL.
