Hi eleanora:

it appears that you have a special IOSP loaded at runtime:

org.ninjoworkstation.server.hdf5.Hdf5FileReader

my tests show that the default HDF5 reader is working correctly.

see

http://www.unidata.ucar.edu/software/netcdf-java/reference/RuntimeLoading.html

for how runtime loading works.

Dear John,
I still have problems during the reading of the HDF5 file I sent you yesterday. The current netcdf-4.2 version cannot read the file also. Are you sure it should work? 

Thanks in advance
Eleonora
