Netcdf Java clients as of 4.3.15 now have limited support for pulling group information from DAP2 DDS. It looks for occurrences of '/' in names and uses that to create groups and place variables and attributes into the specified groups. This feature can be disabled by specifying -Ducar.nc2.cdm.useGroups=false to the java VM. =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: SBZ-133456 Department: Support netCDF Java Priority: Critical Status: Closed
